1.2 EST3 Self Study Course
Introduction to module 1
GE Security’s EST3 is a multiplexed fire alarm network that can
link up to 64 panel controllers (nodes) together to form a peer-
to-peer token ring network. EST3 is designed with modular
hardware and software components to ensure rapid
configuration, installation, and testing. Most of the network
components are quick connect, plug-in assemblies that
provide data processing, inter-panel communications,
response data, audio signal processing, and power
distribution. In addition, each module provides standoffs to
support a variety of operator layer control/display
(Switch/LED) modules. The control/display modules operate
independently from the modules to which they are attached.
As you begin this study of GE Security’s EST3, it is important to
understand that your education has four parts.
Part 1 is this EST3 Self-Study Course. This course introduces
the components of the system, their function and features,
and their installation procedures. This self-study also
introduces you to some basis prerequisite programming
knowledge you will need to learn prior to attending factory
training. Upon completing this course, you will be able to
identify each EST3 component, discuss its function and
features, demonstrate the ability to install it properly and
discuss the basis configuration and programming aspects of
the EST3 system’s 3-SDU configuration applications software.
Part 2 is the EST3 Programming and Network Course, which is
instructor led, factory-based training that takes place at the
GE Security Training Center in Bradenton, Florida. Here you will
receive instruction on state-of-the-art programming
techniques for the EST3 data entry program, called the System
Definition Utility, (3-SDU). This course is application-driven and
is designed to provide you with the most effective means of
programming the integrated EST3 system for fire applications.
For this reason, advanced programming of an EST3 network is
not discussed in this self-study course.
Part 3 is the EST3 Synergy Enabled
3-MODCOM self-study
Course. This course describes the features and capabilities of
the 3-MODCOM and 3-MODCOMP, which are modem and
dialer local rail modules used in integrated EST3 system
environments. This course describes MODCOM operations,
installation considerations and introduces you to the basic
MODCOM configuration and programming process required
to incorporate the MODCOM into an integrated EST3
environment for fire applications.

This self-study course is designed for those who are EST3
certified for fire alarm systems and is the prerequisite training
for the EST3 Synergy Enabled
integrated system certification
course. The MODCOM does not require factory training and
successful completion of this self-study enables your
organization to purchase the MODCOM products and
incorporate them into your EST3 application for fire using the
3-SDU, release 3.0 or greater. The more sophisticated
integrated fire, security and access control MODCOM
applications are discussed in detail in the EST3 Synergy
Enabled
integrated system certification course
Part 4 is the EST3 Synergy Enabled
Course, which is instructor
led, factory-based training that takes place at the GE Security
Training Center in Bradenton, Florida. Here you will receive
instruction on state-of-the-art programming techniques for
the EST3 Synergy Enabled
integrated dialer/modem, fire,
security and access control applications.. This course is
application-driven and is designed to provide you with the
most effective means of programming the fully integrated
EST3 system. This course introduces the components of the
Synergy Enabled
integrated system, their function, and their
installation procedures. Upon completing this course, you will
be able to identify each EST3 Synergy
component, discuss
their function and features, demonstrate the ability to install
them properly, discuss the configuration and programming
aspects of the EST3 system’s advanced integrated dialer, fire,
security and access control applications and perform the
configuration and programming tasks of the EST3 system’s
advanced integrated dialer, fire, security and access control
applications
This enclosures and major components module discusses the
cabinets available for EST3 components. In addition, we
discuss the fundamental components that every EST3 system
cabinet must have. These are each EST3 panel’s 3-CPU central
processing unit, the 3-PPS primary power supply heat sync
assembly, and the 3-PSMON primary power supply monitor
module.
When discussing cabinets, it is important to remember that
the integrated EST3 fire alarm system is modular by design. As
a result, the cabinets you encounter here will be somewhat
different than those you may have encountered in the past.

Associated study
Use the following technical reference manuals and installation
sheets as associated study material for this module:
• EST3 Installation and Service Manual, (P/N 270380, Rev 8.0, or
later)
• EST3 System Operations Manual, (P/N 270382, Rev 8.0, or later)
• EST3 Fire Alarm Support Tools, Online Support System CD
(P/N 270395, Rev 6.0 or later)
The EST3 component installation sheets, Signature Series
component, installation sheets, and other related manuals are
available for your reference on this CD.
All of the required EST3 manuals, installation sheets and
related literature are contained on this CD. However, the
documents published on this CD may not be current to the
release level of the components. The most current EST3
system and Signature literature is available to you via our web
site at www.GE.com. All that’s required in your student PIN
number given you when you received your EST3 self-study kits
and a password you establish when you first login. Refer to
the EST3 Self-Study Course – getting started description in the
front matter of this manual for instructions on using the CD or
connecting to our web site.
This Online Support System CD and our web site are a useful
tools. The minimum system requirements for your PC or
laptop are:
• IBM compatible Pentium computer
• SVGA monitor (800 x 600 pixel at 256 color)
• Windows 2000 or greater
• 2X CD-ROM Drive
• Acrobat Reader software version 7.0 or later
The installation of this CD is easy, simply put CD in your drive
and follow screen prompts to install Acrobat and then start
using the support tools. If Acrobat is already installed simply
put CD in the drive and start using the support tools. It may
be a good idea to install the CD, keep its window open and
minimize/maximize this window to reference literature during
this course.
As stated above, it would be impossible for GE Training to
maintain these installation sheets to their current revisions
levels on the CD, which is updated when major changes to the
EST3 system are made. The actual installation sheets, shipped
with the product components and those posted on our web
site, reflect the current revision levels. It would be good
practice to maintain a current set of these installation sheets
on site and/or at your office.

EST3 Cabinet installation
Read: EST3 Installation and Service Manual > Chapter 1:
System Overview.
Read: related EST3 Installation Sheets (P/N 3100051, Rev. 3.0).
Chapter 1 and the related installation sheets provide an
overview of the EST3 system, its structure and relevant design
and application requirements. This chapter is an excellent
way to get started on this self-study course. In this lesson,
pay particular attention to the physical structure of an EST3
cabinet and the Class A and B wiring considerations for the
Data Network and Audio Risers considerations.
Installation.
In this lesson, pay particular attention to the topic System
installation sequence. In Chapter 5, (Figure 1-1) which
describes the recommended installation sequence. The steps
shown are an excellent example of the sequence of events
that should take place for the successful installation of an
EST3 fire alarm network.
When practical, it is most efficient to develop a startup version
of your project’s application, where you have configured only
the cabinets and modules, minus the field devices (i.e.
Signature devices). This startup version is then downloaded
into each cabinet before the field wiring is connected (i.e.
signature devices). This startup version is used to establish the
cabinet address identity of each node and to limit
troubleshooting to the module level of each node (Local
Troubles). After this phase you will then connect field wiring
and download the full application version and resolve any
field troubles (System Troubles) that may occur.
When a large multi-node system is involved, another labor
saver would be to select a staging area. Each cabinet node
would then be built in the staging area and the startup version
of the applications would be downloaded, into it establishing
its identity. All local troubles would then be resolved. After all
local troubles have been eliminated the cabinet would then be
installed at its final location within the facility and the field
devices connected. After the system has been preconfigured
in this manner, the full application is downloaded via the
network and any system troubles are resolved.

Verify the field wiring per Chapter 5, Preliminary field wiring testing,
Table 5-3

Figure 1-1: System installation sequence.

When you begin this chapter, note the power-limited and non-
power-limited wiring requirements in a typical cabinet,
described in the 3-CAB Series Enclosure Equipment Backboxes
installation sheets (P/N 387557) and 3-CAB-E Series
Equipment Enclosure Doors (P/N 270488 and P/N 387549). In
addition, closely read the cabinet installation instructions in
the 3-CAB and 3-CHAS7 (P/N 270484) installation sheets. Here
you will find step-by-step instructions on assembling the EST3
cabinets.
Pay particular attention to the description of the layers
involved in a full cabinet assembly in Chapter 1, under the
heading System construction. Observe the relationship
between the chassis/rail assembly, local rail modules (LRMs),
and the control/display modules.
As shown in its installation sheet (P/N 270487), the 3-CAB5
cabinet enclosures are different from the 3-CAB7, 3-CAB14
and 3-CAB21 cabinets used for EST3 panels because it is
made for small installations. The 3-CAB5 consists of a
backbox, inner door, and an outer door with a viewing
window. It holds up to 5 modules and two 10 Ah, 12 Vdc
batteries. The modules are plugged into a built-in assembly of
two rails, upper and lower, which are attached to the
sidewalls of the back box. The rails are removable to permit
ready mounting the power supply assembly on the backbox
footprint.
Note: If the battery requirements exceed the battery size
permitted in any cabinet, a remote closet cabinet (install sheet
P/N 270488) may be used. In standard form, these can store
up to two 50 Ah batteries. Optionally, with the 3-BATS battery
shelves installed (install sheet 387338), they can store up to
two 65 Ah batteries. Any battery size larger than this would
require an external battery cabinet.
The remaining EST3 cabinets are the 3-CAB7, 3-CAB14, and
3-CAB21. Each of these cabinets consists of a backbox, an
inner door, and an outer door with a viewing window. The last
digits in the cabinet model number indicate the number of
rail-slots where mounted modules may be installed in each
cabinet type. In these cabinets the rail assemblies are
preinstalled in one of three assembly types called a 3-CHAS7,
3-ASU/CHAS4, or 3-ASU/FT chassis.
Chassis: The chassis assembly is a large, horizontally
mounted U-shaped plate that is mounted to the cabinet’s
backbox. Each of the 3-CHAS7 chassis assemblies contains
one pair of rails. The chassis is best understood as a three
layer-mounting frame.

The 3-CHAS7 chassis, described in 3-CHAS7 Seven Local Rail
Module Chassis installation sheets (P/N 270848), consists of
three layers. Where:
• The first is the inner layer, which is the rear of the chassis
assembly and is attached to the back box. It contains
mounting spaces (footprints) for the non-rail mounted
components which include primary and booster power
supply heat sink assemblies, audio source unit cards, and
firefighters telephone control unit cards. There is a 1/2
footprint used for special application cards such as the rail
chassis expansion card and the CDR-3 Zone Coder card.
• The second is the middle layer of the 3-CHAS7, which is
the upper and lower rail assemblies which allows for the
mounting of up to seven local rail modules (LRMs). The
hardware layer’s LRMs are considered part of this layer.
• The last is the outer layer, which is composed of the
operator layer control/LED panels for each custom
installation.

The 3-ASU/3-CHAS4 chassis is described in the 3-ASU Audio
Source Unit installation sheets (P/N 270482) This description
covers the 3-ASU audio source unit, which consists of the
footprint-mounted 3-ASU controller board, associated cover
assembly (paging microphone and controls), 3-RCIC Rail
Chassis Interface Card, and a 3-CHAS4 rail assembly that
supports four additional optional LRMs.

of the 3-ASU controller board, associated cover assembly
(paging microphone and controls), the 3-FTCU controller
board and associated firefighter’s telephone cover assembly,
and the 3-RCIC Rail Chassis Interface Card.
Figure 1-4: 3-ASU/FT Assembly.

Read: EST3 Installation and Service Manual > Chapter 5: Local
rail module installation.
Local rail module (LRM): Those EST3 components or modules
designed to plug into the rail assemblies are grouped together
as local rail modules (LRMs). They may be dual or single LRMs.
For example, the 3-CPU1, 3-CPU3 and 3-ZA95 LRMs use two
plug-in slot positions, while the other LRMs use a single slot.
As shown in Figure 1-5, each single LRM has a set of hinged
standoffs, permitting control/display modules to be attached.
The 3-ZA90 LRM has two sets of hinged standoffs to supports
two control/display modules. These components are on the
outer layer of the chassis and may be viewed through a lobby
enclosure cabinet with a window on the outer door. Each of
the 3-CPU1 and 3-CPU3 have two sets of hinged standoffs to
attach the 3-LCD or 3-LCDXL front control panels. The 3-LCD
front panel can only be installed on the 3-CPU1 or 3-CPU3.
The 3-LCDXL front panels are installed on the 3-CPU1 or 3-
CPU3 and the next two subsequent slot positions to the right.
Figure 1-5: Hinged Standoff.

The most current information on the EST3 products is
provided in the installation sheets shipped with these
products or on our web site. Always use the sheets shipped
with the product or obtained from our web site for the most
current information.
Note: The control/display modules are not related to the LRM
modules to which they are attached. For example, an LED
annunciator panel attached to the front of a power supply
monitor LRM would operate completely independent of the
power supply monitor. The control/display module is installed
electrically onto the rails through its ribbon cable.
Control/display module operation is determined during the
configuration and programming process.
Figure 1-6 shows the layout of the chassis and it’s associated
layers.
Figure 1-6: 3-CHAS7 chassis views.
The side view in Figure 1-6 shows the ends of the rails
attached to the sides of the chassis. A local rail module card is
plugged into the rails. A control/display module card is
attached to (snap onto) the standoffs on the local rail module.
The front view shows the upper and lower rails without any
modules installed on them. Notice that both the upper and
lower rails contain seven plug-in positions called slots. When a
local rail module is plugged into the rails, it will occupy at least
one upper and one lower slot position, depending on the size
of the LRM module.

Figure 1-7 depicts a detailed look at the rails.
Figure 1-7: Seven-module rail assembly.
As you can see, the upper and lower rails are almost identical.
Each set of rails provides an upper and lower assembly to
mount up to seven modules.
There is a set of four plugs at the right end of each rail. The
two larger outer plugs are for Data In and Data Out. The
smaller inner plugs are for Power In and Power Out. These
plugs are where the connections are made from one chassis
assembly to another within a cabinet.
Details on LRM installation to rails are provided in the EST3
Installation Sheets Manual and the respective LRM’s install
sheets.
In Figure 1-8, a 3-CPU1 or 3-CPU3 panel controller LRM is
installed on the rail assembly. This card is a dual local rail
module; therefore it requires two module spaces or slots on
the rail assembly.

Figure 1-9 shows the typical data and power line connections
between chassis installed within the same cabinet. Since three
sets of rails are shown, it follows that the cabinet of this
example has three chassis installed and must be a 3-CAB21.
Figure 1-9: Inter-rail data and power connections.

This section traces out the wiring paths in Figure 1-9 to
familiarize you with the wiring routes. As you study Figure 1-9,
there are several important points to understand and
remember:
• Each cabinet (panel or node) within a EST3 fire alarm
system network requires one 3-CPU1 or 3-CPU3 panel
controller.
• In standard applications, the 3-CPU1 or 3-CPU3 panel
controller must always be installed in the top chassis
assembly and in the left most, first two module spaces on
the rails.
• Optionally, the 3-CPU1 or 3-CPU3 panel controller can be
physically installed in the middle or bottom chassis
assembly (still in the left most, first two module spaces on
the rails). In this case, you must use the optional 3-CBL-
KIT1 data and power cables. In this cabinet configuration,
even through the chassis’ 3-CPU1 or 3-CPU3 is physically
not in the top chassis it electrically and logically is still in
the first two slots on the rails.
• The chassis rails on which 3-CPU1 or 3-CPU3 is installed
must have Data Out and Power Out connections made
only to the rail connectors.
• Chassis rails on which the 3-CPU1 or 3-CPU3 is installed
cannot have connections to any of the chassis rail Data In
or Power In connectors.
• Based on the proceeding wiring requirements, the top set
of rails in Figure 1-9 is wired for the 3-CPU1 or3-CPU3.
• Based upon the associated cable part numbers, the rail
power and data cables are manufactured with the
required connectors and cable lengths. The data cable is a
ribbon cable, while the power cables are large, three- or
four-bundled wire cables.
Now review the 3-CAB7, 3-CAB14 and 3-CAB21 specifications
in the installation sheets. Notice the following information
about each cabinet:
• Each holds up to two 17 Ah 12 Vdc batteries.
• Each comes in enamel gray or red.

• 3-RCC Series Remote Closet
Cabinet P/N 270486
• 3-RCC-E Series Remote Closet

The RCC series cabinets are designed for distant locations
where visual displays, such as the 3-LCD displays or
control/display modules, are not desired or needed. The back
box is the same as the CAB series models, but the outer door
is solid metal without a viewing glass. This series does not
include an inner door.
There are three models:
• 3-RCC7: One chassis, 7 module spaces
• 3-RCC14: Two chassis, 14 module spaces
• 3-RCC21: Three chassis, 21 module spaces

3-CPU3 panel controllers: These 3-CPU1 or 3-CPU3 central
processor units, or panel controllers, are the control element
for all other modules and operator interface panels installed
within a cabinet enclosure.
Figure 1-10: 3-CPU1 and 3-CPU3.

These CPUs process all information from the modules installed
on the chassis rails within a cabinet as well as processing
data received form the network via the network data circuit
Older panels may be equipped with the 3-CPU or 3-CPU1
central processing units. The 3-CPU3 is a replacement for the
3-CPU and 3-CPU1. The 3-CPU has configuration limitations
of Class B audio only, which are discussed in this module.
There are four types of CPUs you may come across in the field:
• 3-CPU – Older applications, Class B audio only.
• 3-ANNCPU - remote annunciator applications, with out
audio.
• 3-CPU1 - Class A or B Audio.
• 3-CPU3 - Class A or B Audio.
Let’s review what you have already learned about the
installation of the EST3 CPUs:
• One CPU must be installed in every cabinet (node) within a
system.
• The CPU occupies the first two left-most, electrical module
positions on the top rail assembly.
• Only Power Out and Data Out connections are made on
the rail assembly in which the CPU resides.
As you read through this section, note the following CPU
parameters:
• Available EEPROM and RAM capacity.
• 3-RS485 communication for data network and audio
risers, Class A or Class B.
• Available ports, circuit length.
• Each CPU automatically identifies (addresses) and
supervises all modules within its cabinet (network node).
• Provides Form C alarm, supervisory, and trouble contacts
that react to conditions within the network specified by
network routing configuration process as described in the
Help utility of the 3-SDU System Definition Utility.
• Contacts may react to all cabinets or a subset of cabinets
specified during the configuration process for network
routing for each CPU within the system.
• Provides 3-RS485 communications (Class A or B) with
other CPUs on a data network riser.
• Provides command and control for the 8-channel audio
network riser.

• Supports a Class A or B audio riser for 3-CPU1 and 3-CPU3
applications and a Class B only audio riser for older 3-CPU
applications.
• Supports two optional RS232 ports, which can be
configured for auxiliary, printer, zone-coder or graphic
front-end operation.
• Supports both 3-LCD and 3-LCDXL main control panel
installation. Where these LCDs can only be installed on
the 3-CPU1 and 3-CPU3 and these CPUs will not support
the other control/display modules.
Caution: The 3-CPU1 and 3-CPU3 are shipped from the
factory with the most current microcode versions installed.
During the periods when new software is being released it is
critical that you verify that the microcode onboard your CPUs
matches the microcode you are using in your System
Development Utility (3-SDU) programming environment.
This is easily accomplished by performing a version request
prior to downloading your applications software into the your
systems CPU’s.
Now let’s take a closer look at the 3-CPU1 and 3-CPU3 LRM
modules illustrated in Figure 1-11.
On the front of the 3-CPU1 and 3-CPU3 LRM modules you will
find:
• (J5) RJ-11 jack. The (J5) RJ-11 jack on the front top left
corner is used for downloading from the data entry
program (SDU).
• TB-1 terminal block. TB-1 is the connection point for the
alarm, supervisory, and trouble contacts. These are used
primarily for off-premises notification.
• J1 ribbon connector. J1 accepts the ribbon cable from
either a 3-LCD or 3-LCDXL Display panel when used.
Note: From a field techs point of view the difference
between the 3-CPU1 and 3-CPU3 is the placement of the
J1 ribbon connector. The new placement for this
connector on the 3-CPU3 provides greater integrity and
stability for the ribbon cable from the 3-LCD or 3-LCDXL
main control panels.
Note: Also note that the 3-CPU3 is the replacement part
for 3-CPU1 LRM modules. The 3-CPU3 is the replacement
for older 3-CPU and 3-CPU1 LRM modules.

• Communication LEDs.
• TB2 terminal block.
TB1 and TB2 are detailed in the 3-CPU3 installation sheet and
Chapter 1 the EST3 Installation and Service Manual. TB2
provides connections for the:
• Network data risers (CPU to CPU communications).
• Network audio riser.
• Two auxiliary 3-RS232 ports.
Caution: Downloading 3-CPU microcode versions earlier than
1.33 into a 3-CPU1 or 3-CPU3 will disable connector J5 (RJ-11).
The 3-CPU1 and 3-CPU3 are shipped with the most recent
microcode installed.
For networks where older 3-CPU’s are present with earlier
than 1.33 microcode versions; EST strongly recommends
updating the program and microcode. Where existing CPUs
have been downloaded with an earlier version which disables
connector J5, downloads may still be accomplished through
the TB2 RS-232 port when the 3-RS232 option card is installed.
Programmers can verify the version of existing CPUs by
performing a version request using the 3-SDU.
On the back of the CPU LRM modules you will find:
• P1A, P1B, P2A, and P2B rail connectors. P1A, P1B, P2A, and
P2B plug into the corresponding upper and lower rail
assembly connectors.
• J2 daughter board connector. J2 is used for 3-RS485 or
3-FIB fiber optic network communication cards.
• J3 daughter board connector. J3 is for an ancillary 3-
RS232 communication card, which supports the two RS-
232 ports.
• J4A/J4B daughter board connectors. J4A/J4B are for the
memory expansion card (not used for 3-CPU3
applications).
The 3-RS485 Card is required for 3-ANNCPU remote
annunciator applications. It is part of a daughter card factory
mounted on standoffs on the 3-ANNCPU modules. The other
options cards are not available for 3-ANNCPU applications.
The 3-CPU1 and 3-CPU3 operating power is from the rail
assembly. Power for the rails comes from the 3-PPS/M primary
power supply and optionally from the 3-BPS/M booster power
supplies, discussed later.

The 3-ANNCPU LRM modules power must be supplied from an
external +24 Vdc source (e.g., +24 Vdc AUX power from TB1 on
the 3-PSMON or 3-BSMON modules).
The EST3 system network supports up to 64 3-CPU1, 3-CPU3
and/or 3-ANNCPU panel controllers (nodes).
TB1 and TB2: The components that are attached to each of
the 3-CPU1 or 3-CPU3 circuit boards, labeled as TB1 or TB2,
are part of a two-piece termination block assembly, which
supports the EST3 snap fit construction. In Figure 1-12 the
board section is called the header termination block and is the
male plug part of the assembly.
Figure 1-12: Header termination block.
The other part of the block assembly, called the connector
termination block shown in Figure 1-13, is where all field
wiring is connected. The connector termination block provides
the female plug part of the assembly.
LABEL

Figure 1-13: Connector termination block.

As you can see in Figure 1-13, field wiring is attached to the
connector termination block. One advantage of this is that
field wiring can be connected without requiring the prior
installation of the local rail module (LRM). When ready, the
connector termination block is plugged into the header
termination block on the appropriate module. A second
advantage to using the connector terminal block is during
local rail module replacement. In this case, you simply unplug
the connector termination blocks from the old module,
remove the old module from the rail assembly, install the new
module on the rail assembly, and plug the connector
termination blocks into the new one.
As stated at the beginning of this module, an EST3 integrated
fire alarm panel may operate in standalone mode or as part of
a network. In standalone mode, the system consists of one
cabinet with one 3-CPU1 or 3-CPU3 controlling all the
modules and communication within the single cabinet.
In network applications there are multiple cabinets, each with
its own 3-CPU1 or 3-CPU3 and each communicating with the
others. EST3 uses a unique, state-of-the-art communications
protocol to provide rapid, accurate communication between
these CPU panels.

Network theory
Read: EST3 Installation and Service Manual, Chapter 1: System
Overview:
• Digital Network Subsystem
• Network Applications
Multi-priority, peer-to-peer, token passing network is a
microprocessor communication network where electronically
there is no master panel. Each panel in the network must
contain a 3-CPU1or 3-CPU3 with RS-485 or 3-FIB network
card and is equally capable and provides what is termed
peer-to-peer communication. A token passing network
operates differently from a traditional multi-drop network.
Where, in a token passing network, the panel having the
‘token’ is temporarily in charge of the network and there is no
master panel.
GE Security’s EST3 token network is logically sequenced.
Message traffic depends upon the priority of the message, the
alarms having the highest priority, supervisory next, and then
troubles. Monitor messages have the lowest priority.
Each panel is given permission to send its messages by the
token being passed to it. If a panel receives the token and it is
not in alarm, its first action is to send out a high priority
invitation to speak. If any panel in the network has an alarm
message, which is a high priority, the token is immediately
passed to that panel. The panel in alarm then transmits its
alarm message, followed immediately by a high priority
invitation for any other panel in alarm.
This process continues until all alarm messages have been
transmitted. The last panel with an alarm message will
transmit any other low priority messages and then pass the
token to the next panel in the network.
If the panel having the token receives no response to its high
priority invitation, it transmits any low priority messages it has
and passes the token to the next panel on the network. If the
panel receives no response to the high priority invitation and
has no messages, it passes the token immediately to the next
panel on the network.
This may seem to be very time consuming, but the token is
electronically passed through the network approximately 20
times a second in a fully configured 64 node EST3 network
with no alarms. Alarm conditions in this network report to the
panel within 3 seconds.

3-CPU1 and 3-CPU3 option cards
Read: The following EST3 Installation Sheet::
Figure 1-14: CPU Option Cards..
3-RS485 network communications card
Figure 1-15: 3-RS485 network (A/B/R) communications card.

The 3-RS485 network communications card shown in Figure
1-15 is inserted into J2 on the back of the 3-CPU1 and 3-CPU3
modules. It provides two independent, RS-485 communication
circuits (Class A or Class B). One is used for the CPU-to-CPU
data network communications. The other is used for the
network audio riser (Class A or Class B).
Note: The older 3-CPU provides Class B audio only. The newer
3-CPU1 and 3-CPU3 audio riser can be Class A or B.
This card is required on every 3-CPU1 or 3-CPU3 in an EST3
network using RS-485 communication protocol. This card
supports the two Data Network RS-485 circuit connections on
TB2 of these CPUs (Network OUT A and Network IN B).
The 3-RS485 Card is required in 3-ANNCPU applications and is
part of a daughter card mounted on the 3-ANNCPU module
as shown in 3-ANNCPU Annunciator Controller Module
installation sheet (P/N 3100650).
There are four versions of the 3-RS485 option card that you
may encounter in the field:
• For older 3-CPU based systems there is a 3-RS485 card,
which provides for Class A and B data network risers and
Class B only audio network riser. This card has been
discontinued.
• For older 3-CPU based systems there is a 3-RS485R card,
which provides Class A and Class B data network risers
and Class B only audio network riser. This card is currently
available for use on 3-CPU systems. This card is used to
replace the original RS-485 cards that may have failed.
This card is also used to replace the older 3-CPU’s which
have failed with 3-CPU1’s or 3-COU3’s. Using the 3-
RS485R cards enables you to use the 3-CPU1 or 3-CPU3
as a replacement card in 3-CPU systems. This card
enables 3-CPUs, 3-CPU1s and 3-CPU3s to exist and
communicate over the same data network riser.
• For 3-CPU1 and 3-CPU3 systems there is a 3-RS485B card,
which provides Class A and Class B data network and
Class B only audio network risers only. This card is used for
3-CPU1 and 3-CPU3 systems applications only.
• For 3-CPU1 and 3-CPU3 systems there is a 3-RS485A card,
which provides Class A and Class B data network and
Class A and Class B audio network risers. This card is also
used for 3-CPU1 and 3-CPU3 systems applications only.

Caution: Option cards may be damaged or their operation
compromised when installed on the incorrect processing unit.
Amplifier firmware (PAL Chips) must be compatible with the
processing unit as listed in Table 1-1. Existing 3-CPU’s cannot
accept the 3-RS485A or 3-RS485B cards. The newer 3-CPU1
and 3-CPU3 cannot use the older 3-CPU 3-RS485 option card.
When using 3-RS485A or 3-RS485B option cards you must
upgrade the 3-ZA15 and 3-ZA30 amplifier firmware, if these
amps exist in your system, using the improved algorithm. The
firmware for the newer 3-ZA20 (A or B) and 3-ZA40 (A or B) is
already current. In all cases, refer to the related TECH FAXes
and 3-SDU release notes for firmware requirements.

Before we look at the other options cards, let’s take a few
minutes to review network wiring. To start, notice TB2 located
on the bottom of the 3-CPU1 and 3-CPU3, which is shown in
Figure 1-16. On the top of this figure, the portion of TB2 that is
mounted on the 3-CPU1 or 3-CPU3 modules is shown. Notice
the label that indicates terminal block connections.
Where:
• Network data connections are made to plugs 17 through
20.
• Network audio connections are made to plugs 9 through
16.
• 2 optional RS-232 port connections are plugs 1 through 8.
A front view of the TB2 snap-fit plug, where field-wiring
connections are made, is shown in the middle of this figure.
Existing 3-CPU modules have TB2 audio-in polarity reversed
from current 3-CPU1 and 3-CPU3 modules
A bottom view of this snap-fit plug is illustrated at the bottom
of this figure.

Figure 1-16: TB2 on the 3-CPU1 and 3-CPU3 modules
The network connections for the 3-ANNCPU of the remote
annunciators are made at TB1 at the top of this module. These
connections will be covered later in this course.
In a standalone configuration there is no need for 3-RS485
cards, since no network data connections are made.
In standalone application where the 3-RS485 card is not
present, the Primary Audio Out from the 3-ASU card is
connected to the Audio A Out (plugs 13 and 14) on the 3-
CPU1’s or 3-CPU3’s TB2.

In Figure 1-17, you can see network data connections are
easy to make. Network data input from the previous panel
(node) within a system are made to TB2 terminals 20 and 19
(A+ and A-). The Figures given in Chapter 1 of the EST3
Installation and Service Manual and the 3-CPU3 installation
sheet (P/N 3100648 provide additional information. Network
data output to the next panel within a system are to TB2
terminals 17 and 18 (B+ and B-).
Figure 1-17: 3-CPU1 and 3-CPU3 network data
connections.
Figure 1-18 illustrates Class A and Class B network
interconnections. A 3-CPU1 or 3-CPU3 panel controller has
two bi-directional terminal connections for wiring the panel to
the network data riser (A and B terminals). The correct method
for wiring a Class B network data riser is to connect the
isolated network B terminal connections on one panel
controller to the non-isolated network A terminal connections
on the next, as shown in Figure 1-17. Up to 64 3-CPU1s, 3-
CPU3’s or 3-ANNCPUs may be connected in this way.
Class A is wired in the same way, however the B terminals of
the last 3-CPU1 or 3-CPU3 on the network are wired to the A
terminals on the first 3-CPU1 or 3-CPU3 as the Class A return.
Caution: When downloading to a 3-CPU1’s J5 RJ11 connector,
the set of A network terminals are disables on that CPU. As
shown in Figure 1-18, when performing a network download
in a Class B configuration, always connect to the node without
network connections to the A terminals.
Also, when performing a network download to a Class A
configured system the panel will indicate a Class A Network
Failure during the download process. This is normal.

Use this panel’s CPU (no connection to it's A port) for downloading to

CPU in a Class B network will prevent the downloading of all data to
those CPUs connected to a CPU’s A port.
Figure 1-18: Class A and B network node interconnections.
Now let’s look at network audio wiring. There are two methods
for wiring network audio, based on the type of CPU used in
your system. In the older 3-CPU systems network, audio is
limited to Class B only. In the 3-CPU1 and 3-CPU3 systems,
network audio can be configured Class A or B.
Figure 1-19 shows the 3-CPU1 and 3-CPU3 TB2 audio
connections for standalone operation, where the 3-ASU TB1
terminals 1 and 2 for primary audio data, are connected to
the 3-CPU1 TB2 terminals 14 and 13, which are for Audio Out.
Because there is no 3-RS485 option card for standalone
applications the audio connections are made to the Audio Out
for these systems.
Connecting the ASU primary audio to the Audio In terminals in
a standalone configuration will cause a configuration fault
within the system. If it is desired to connect to the Audio In
terminals, a 3-RS485 option card must be added to the
standalone application.

Only one 3-ASU can control a network audio riser in the three
types of CPU applications. The 3-CPU network node
interconnection uses the RS-485R, while the 3-CPU1 or 3-
CPU3 network node utilizes the RS-485B. When more than one
firefighter telephone panel and riser are required in a 3-CPU1

installed with the additional 3-FTCU. However, this ASU cannot
be connected to the existing network audio riser.

3-FIB fiber optic communications cards
• 3-FIB/3-FIBA Fiber Optic Communications
Interface Module P/N 378333
Figure 1-23: 3-FIB/A Fiber optic communications cards
The fiber optic communications card (3-FIB/A) provides a Class
A and Class B data network riser and a Class A and Class B
audio network riser, used for 3-CPU1 and 3-CPU3 applications
The 3-FIB/A fiber optic interface consists of two cards
connected by a ribbon cable:
• The fiber optics communication electronics card which
mounts into J2 on the back of the 3-CPU1 or 3-CPU3
module
• The fiber optics communication interface card which
mounts onto a 3-MPFIB mounting plate that is installed
onto the bottom of the chassis assembly
The 3-FIB/A interface provides two independent fiber optic
circuits (Class A or Class B). One is used to connect network
data riser of two CPU panel controllers together. The other
provides the network fiber optic audio riser for older 3-CPU
Class B only and for 3-CPU1and 3-CPU3 Class A and B
applications. The 2-card interface is required on each 3-
CPU1or 3-CPU3 that is using the fiber optic communications
protocol. The 3-FIB/A electronics card supports using fiber
optics within a copper wire network. In that, fiber optic links
can be used in portions of the network where fiber is desired

and standard copper wire links can be used in the remainder
of the network.
Figure 1-24: 3-FIB/A Fiber optic 3-CHAS7 installation.
Figure 1-25: 3-FIB/A Fiber optic 3-CAB5 installation.
The 3-FIB/A interface card provides ST fiber optic connectors
and a secondary power option. This permits communications
to flow through this module even with panel power
disconnected.
Using the 3-FIB/A fiber optic interface and fiber optic cables to
transmit network data and audio offers the following
advantages:
• Electrical isolation.
• Lightening surge current and transient immunity.
• EMI/RFI noise immunity.
• No spark or fire hazard.
• No radiation or noise emissions.
• Short circuit protection (i.e. no current flow).
• Low maintenance.
• Lightweight, small diameter fiber optic cables.
• Cost effective.

3-RS232 ancillary communications card
Read: EST3 Installation and Service Manual > Chapter 6: Power
up and testing:
• 3-RS232 Card installed in CPU.
Figure 1-26: 3-RS232 ancillary communications card.
This option card is used to add two RS-232 ports to the 3-
CPU1 or 3-CPU3. The 3-RS232 communications card plugs
into J3 on the back of the 3-CPU1or 3-CPU3 module. This card
adds two program configurable serial ports at TB2 for the
connection of printers, PCs, CDR-3 coder and/or a gateway
graphics front-end.
Refer to Figure 1-27 for the TB2 terminals used for 3-RS232
connections. The 3-RS232 Port 1 is an isolated port on TB2
terminals 5 through 8 and the 3-RS232 Port 2 is on TB2
terminals 1 through 4.
These ports are configurable for supervised or unsupervised
operation. When a port is configured using the EST3
applications software and the port is configured for
unsupervised operation, when nothing is connected to it, it
does not report to the control panel.

EST3 power supplies
Installation:
• AC power and DC battery wiring.
Power-up and testing:
• Cabinet power-up procedures.
• Power Supply P/N 270495
Figure 1-28: EST3 Power Supply and Monitor Module.
Two types of power supply are available for EST3 system
applications. The first, called a primary power supply (PPS), is
used in every cabinet. The second, called a booster power
supply (BPS), is used when additional power is required on a
cabinet-by-cabinet basis. Depending upon the cabinet size
and power requirements, a primary power supply and up to
three booster power supplies may be used in one cabinet.
Each type power supply consists of two parts:
• A power supply heat sink assembly mounted on the
chassis footprint.
• A monitor module mounted on the chassis rail assembly.

Primary power supply, 3-PPS/M or 3-PPS/M-230
3-PPS/M primary power supply: The 3-PPS/M provides the
required power and related supervision functions for the
panel (cabinet) in which it is installed. The power supply
consists of two major components. The first is the heat sink
assembly (3-PPS), which mounts on the rear of the top chassis
assembly behind the rails on the left-most footprint.
The second component is the power supply monitor module
(3-PSMON). The 3-PSMON is a single local rail module installed
into the third rail slot next to the 3-CPU1 or 3-CPU3 module.
This module is often called the driver module because it
monitors the primary power supply.
The 3-PPS/M requires 120 Vac at 50-60 Hz, while the 3-PPS/M-
230 requires 230 Vac at 50-60 Hz.
In your review of the installation manual, look for the following
power supply specifications:
• Provides filtered regulated power to the rail assemblies.
• Rated at 24 Vdc at 7.0 A for all outputs.
• Provides two independent, power limited, supervised
auxiliary 24 Vdc outputs. Current output may be up to 3.5
Amps each, depending on the amount of current being
supplied to the rail and control/display modules.
• Terminal connections for these outputs are located on TB1
of the 3-PSMON monitor module.
• Supervises and charges 10 to 65 Ah batteries.
• Features a dual rate, constant current battery charger
with automatic temperature compensation.
• Incoming ac power and battery charger connections are
made on the 3-PPS heat sink assembly, which separates
these connections from the panel’s power limited wiring.
• Battery monitor circuit disconnects the batteries when
battery voltage drops to 20 Vdc or below
• Automatically transfers to batteries when input ac power
drops to 102 Vac or below
Note: The maximum output current of the primary power
supply is 7.0 Amps. This limitation also applies to the booster
power supply. The total current supplied to the rail assembly
and the two output terminals on the monitor modules cannot
exceed 7.0 Amps.

When the primary power supply is operating with a group of
booster power supplies (up to three in the 3-CAB14 or
3-CAB21), and one of the boosters fails, the primary power
supply determines the ability of the remaining booster power
supplies and itself to maintain the load demand. Should it
determine that the load has exceeded the ability of the
remaining power supplies, the standby batteries are
automatically switched in.
3-PPS heat sink assembly: The 3-PPS heat-sink assembly is
too large and heavy to mount on the rails. As previously
stated, the chassis assembly is connected directly to the back
box. The 3-PPS heat-sink assembly is mounted on threaded
studs (left-most footprint) located on the rear of the chassis.
Let’s take a closer look at the 3-PPS in Figure 1-29.

• TB2: provides the terminal points for the battery charger
and temperature risers.
• P2: connection point for the power cable that runs to P6

• P3: connection for the 16-pin data ribbon cable that runs
to P4 on the back of the 3-PSMON.
The 3-PPS/M specifications of the installation sheets provide
details about 3-PPS/M mounting and termination.
3-PSMON monitor module: The 3-PSMON monitor module
provides the interface between the 3-PPS heat sink and the
chassis rail assembly. The 3-PSMON provides the required
data and power connections to the chassis rails. As previously
stated, the monitor module is a single local rail module. This
module has hinged standoffs, which support mounting an
independent control/LED panel or protective blank faceplate.

Note: The 3-PSMON monitor module must be mounted in the
rail space (slot 3) immediately adjacent to the 3-CPU1 or 3-
CPU3 panel controller module.
When additional power beyond the capacity of the 3-PPS/M is
required, the 3-BPS/M booster power supply is used.

Booster power supply, 3-BPS/M or 3-BPS/M-230
3-BPS/M booster power supply: The 3-BPS/M is used to
provide power over and above that of the 3-PPS/M primary
power supply. Up to three 3-BPS/M power supplies may be
added to a cabinet, depending on cabinet size. Each chassis
can hold up to two supplies. Up to 28 Amps is available per
cabinet for internal and external applications with a full
compliment of one 3-PPS and three 3-BPS.
Like the 3-PPS/M, the 3-BPS/M booster power supply consists
of two major components:
• The 3-BPS heat sink assembly, which mounts on the
footprints on the rear of the chassis.
• The 3-BPMON booster monitor module, which is a local rail
module.
Due to cable lengths, the 3-BPMON booster monitor module
can only be installed into slots 3 and/or 5 on the rail assembly.
In Figure 1-33, look for the following 3-BPS heat sink assembly
connections:
• TB1 terminal connections for primary ac voltage, 120 Vac
or 230 Vac.
• TB2 terminal points for the supervised battery riser.
• P2 connection point for the power cable that runs to P6 on
the back of the 3-BPMON monitor module.
• P3 connection for the 14-pin data ribbon cable that runs
to P4 on the back of the 3-BPMON.
In Figure 1-33, it would appear that the 3-BPS looks exactly
like the 3-PPS. Actually, there are three distinctive exceptions.
The transformer in the top center of the board below TB1, the
battery terminal block has only two terminals and the P3 data
connector has only 14 pins.. These make it easy to distinguish
between the primary and booster power supplies.
In this section, you will see some similarities between the
primary and booster power supplies:
• Each provides filtered, regulated power to the rail
assemblies.
• Each 3-BPS is rated at 24 Vdc at 7.0 A for all outputs.

• Two independent, power limited, supervised 24 Vdc
outputs. (Current output may be up to 3.5 A each,
depending on the amount of current being supplied to the
rail and control/display modules).
• Terminal connections for these outputs are located on the
3-BPMON Monitor Module, TB1.
• Incoming ac power and battery connections are made on
the 3-BPS heat sink assembly, which separates these
connections from the panel’s power limited wiring.
• Automatically transfers to batteries when input ac power
drops to 102 Vac or below.

The differences between booster and primary power supplies
are that boosters:
• Do not have a constant current battery charger.
• Do not monitor battery circuit.
• Do not have battery-charging capability, but supervises its
own connection to the standby batteries.
Note: The primary power supply and booster power supplies
in a cabinet share a common set of standby batteries.
However, only the primary power supply charges and
monitors the batteries. The 3-BPS only supervises its leads
going to the battery.
In the event of a 3-BPS failure, a trouble is annunciated at the
front panel and the panel load is redistributed among the
remaining power supplies. Should the required power exceed
the capabilities of the remaining power supplies, the system
automatically transfers to the batteries.
The 3-BPMON monitor module is the interface between 3-BPS
heat sink assembly and the rail assembly. It is a local rail
module, which uses one module position on the rails and has
standoffs to mount a control/display module or blank cover
on its front.
The 3-BPMON looks almost exactly like the 3-PSMON, except
for the number of IC chips on the front of the module board.
Also, the P4 connector on the 3-PSMON has 16 pins, while the
P4 connector on the 3-BPMON has 14 pins. The only way to
insure you are installing the correct monitor module is to
double-check the part numbers of the components.
3-BPMON monitor module: The 3-BPMON monitor module
provides the interface between the 3-BPS heat sink and the
chassis rail assembly. The 3-BPMON provides the required
data and power connections to the chassis rails. As previously
stated, the monitor module is a single local rail module. This
module has hinged standoffs, which support mounting an
independent control/LED panel or protective blank faceplate.
Using Figure 1-34 look for the following details on the front of
the monitor module:
• J1 is the terminal connection for the ribbon cable from
any control/LED module occupying the hinged standoffs.
• TB1 is the terminal point for the two independent auxiliary
24 Vdc outputs. The current output may be up to 3.5 A for
each, depending on the amount of current being supplied
to the rail and control/display modules.

EST3 component installation
As you have learned, GE Security’s EST3 system components
are modular in construction and specifically designed for
installation into its unique chassis rail assembly. The figures
on the following pages should help in understanding how all
of this comes together. We will start with an empty chassis rail
assembly, shown below:

Figure 1-36: Empty 3-CHAS7 chassis assembly.
The first step in the installation of components into the chassis
is to install the ones that are mounted at the rear of the
chassis, beneath the rail assembly. Let’s begin by installing a
3-PPS power supply heat sink assembly on the threaded studs
of the rear chassis, left-most footprint, as shown below:

Due to the size of the 3-PPS and 3-BPS assemblies, there is a
limit of two per chassis. In cases where you require the full
cabinet load of one 3-PPS and three 3-BPS power supplies,
you must mount them on at least two chassis assemblies.
Remember, that the 3-PSMON will always be mounted
immediately adjacent to the 3-CPU1 or 3-CPU3 in slot 3 and
the 3-BPMONs will be mounted in slots 3 and 5. The 3-BPS/M
power supplies should be located in the vicinity of the heaviest
loads. Review the instructions on the location of booster
supplies and the maximum allowable chassis assembly
current.
The next step in panel configuration would be to connect the
power supply-to-monitor cables to the 3-PPS and 3-BPS
assemblies. These are connected to the corresponding
monitor modules later.
Now you are ready to install the 3-CPU1 or 3-CPU3 panel
controller module on the rail assembly. Prior to doing this,
ensure that the desired network communication cards (3-
RS485 or 3-FIB) and 3-RS232 communications cards are
installed on the back.
If the fiber optic option is used, you’ll need to install the 3-FIB
fiber optics communications card into J2 on the back of the
respective CPU module. For 3-CAB5 applications the fiber
optics communications interface card and mounting plate are
installed on the half-footprint on the back of the chassis.
For 3-CAB7, 3-CAB14 and 3-CAB21 applications the fiber
optics communications interface card and mounting plate are
installed on the bottom rail assembly of the chassis containing
the CPU module.

The 3-CPU1 or 3-CPU3 take the first two module (left-most)
slots on the first (top) chassis in the cabinet.
Figure 1-38: 3-CPU1 (shown) or 3-CPU3 module installed in the first
two module spaces or slots
With the CPU Controller module now installed on the rail
assembly, you are ready to install the 3-PSMON in slot 3,
immediately adjacent to the 3-CPU1 or 3-CPU3. Connect the
power and data cables you installed with the 3-PPS assembly,
to the appropriate plugs on the 3-PSMON and then plug it
onto rail assembly.
Figure 1-39: 3-PSMON Monitor module installed on rail assembly
The 3-CPU1 and 3-CPU3 modules have hinged standoffs that
are designed to take the 3-LCD or 3-LCDXL display panels.
These LCD displays will be discussed later. Let’s install one
here to demonstrate the use of the hinged standoffs.

As you will learn later, these LCD displays provide the operator
interface with the EST3 network. It is important to remember
that this component is optional. While you are required to
install a LCD in the cabinet where operator interface is desired
(at least one in the system), it is not required with any other
CPU in the networked system. If the LCD display is not needed
for this cabinet, two blank plates may be installed on the
CPU’s standoffs.
To install the LCD Display panel (3-LCD shown), simply connect
the ribbon cable between the respective LCD and J1 on the
respective CPU module and snap the LCD into the left-most
standoffs. Remember, to route the ribbon cable so it goes into
the module to the right.
Figure 1-40: Chassis with 3-LCD display panel installed
Note: When installing the 3-LCDXL (not shown) this display
take up four module slots (1 through 4). This 3-LCDXL should
not be installed until the optional LRM for your applications is
installed into slot 4.

You have learned that all of the single slot local rail modules
(i.e. 3-PSMON) have hinged standoffs for installing
control/display modules. For the example of this lesson let’s
install a 12 switch, 24 LED annunciator panel (3-12/Sx) on the
hinged standoffs of the 3-PSMON.
Figure 1-41: 3-12/Sxx Control/display module installed
We have installed a 3-PPS heat sink assembly on the rear of
the chassis, the 3-CPU1 panel controller and 3-PSMON
monitor modules on the rail assembly, and a 3-LCD display
and a 12-switch, 24-LED control/display module on top of
these. There are four local rail module spaces left for use.
These can be used for optional LRMs that will be covered later
in this course.
The inner door of the cabinet is cut out so only those
components on the hinged standoffs may be seen. In this
way, the same components may be viewed through the
window of the outer door.
This lesson demonstrates the typical method of installation, in
three layers, that should be repeated for all the systems
cabinets.

System power-up and testing > Cabinet power-up procedure
Read this topic carefully, it makes some substantially
important points including:
• Connect ac power prior to connecting the batteries.
• The CPU fail light is not an uncommon occurrence when
the 3-CPU1 is initializing on power up.
• The CPU fail light will clear when the power up sequence
has completed.
• Chapter 5 lists the program initial turn on downloading
procedure. On the initial download of a network (either
Class A or Class B), you must download to each 3-CPU1 or
3-CPU3 individually to establish its identity.
Note: This enables you to establish the identity of each node
within the system network. Chapter 5 in the installation
manual recommends that a start-up version of your project’s
application be downloaded for this purpose.
On subsequent downloads:
• In Class A or B the entire network may be downloaded
from any cabinet at either the 3-RS485 RJ45 plug or the 3-
RS232 TB2 serial port.
• If an audio source unit (ASU) is part of the network, its
database may be downloaded directly into the ASU or via
the network CPU.
• If a 3-SSDC or 3-SDDC signature driver controller is
installed, specific Signature device data may be

3-LCD and 3-LCDXL displays
Introduction to module 2
The 3-LCD and 3-LCDXL are special EST3 control/display
modules. These display modules mount on the hinged
standoffs of the 3-CPU1or 3-CPU3 Central Processor modules
and provides the operator interface for standalone or network
system configurations.
Only one 3-LCD or 3-LCDXL1 display is required for an entire
network, located at the point (node) of control. However,
additional LCD displays can be added to any CPU in the
network to provide remote control and annunciation. These
LCD displays are also provided with the 3-ANNCPU for EST-3
remote annunciator applications.
This module of the self-study course describes the 3-LCD and
3-LCDXL1 features, their basic operation, and the special
functions they can perform. We also discuss the other
control/LED display panels available for EST3 fire alarm
networks. These control/LED display panels are installed on
the hinged standoffs of typical local rail modules.
Finally, we will look at the addressing scheme used in EST3
systems. This will help you to understand how a system is laid
out and permit you to read address information on these LCD
displays effectively.

Introduction.
The 3-LCD and 3-LCDXL1 control/display modules contain a
group of features and functions in the form of an LCD, LEDs
and switches. The LEDs and switches are programmed to
respond to or to activate functions for a specific group of EST3
cabinets within the EST3 system network.

Feature/function domain: A domain is the specific cabinet or
group of EST3 cabinets affected when a feature or function is
activated at the 3-LCD or 3-LCDXL1 display module.
Three domains are available:
• Local: Only the cabinet in which the 3-LCD or 3-LCDXL1
display is installed responds to the function that is
activated.
• Group: A predefined group of cabinets respond to the
function activated.
• Global: All the cabinets in the network respond to the
activated function.
Creating a domain is accomplished in the system definition
utility (SDU) by configuring network and message routing.
Through the configure network or message routing process
you can select the panel or group of panels that respond to
the following specific features:
• State: Specifies panel or group of panels that alarm,
supervisory, trouble, and monitor off-normal event status
messages are accepted from.
• Reset switch: Specifies panel or group of panels to which
reset commands are sent.
• Alarm silence switch: Specifies panel or group of panels to
which alarm silence commands are sent.
• Trouble silence switch: Specifies panel or group of panels
to which trouble silence commands are sent.
• Drill switch: Specifies panel or group of panels to which
drill commands are sent.
• Acknowledge switches: Specifies panel or group of panels
to which acknowledge commands are sent.
Network routing (3-LCD or 3-LCDXL1) domain) is established
during the system configuration process using the 3-SDU. The
EST3 system default is global. This means that the configured
network routing defaults to ALL CABINETS.
In this case if you press the Reset switch on any 3-LCD or 3-
LCDXL1 within a network, every cabinet in that network will
reset. Additionally, all changes of state within the entire
network are reported to and displayed by all LCD display
panels.

Actually, these conditions are what you might normally expect
and want. Nevertheless, let’s look at an example, where this
might not be the case.
A B
Figure 2-4: Network example.
Figure 2-4 shows two large buildings separated by a large
parking lot. One EST3 fire alarm network protects both
buildings. The network consists of five EST3 cabinets (nodes) in
Building A (1 through 5) and five EST3 cabinets (nodes) in
Building B (6 through 10). Cabinets 1 and 6 are located on the
ground floor of their respective buildings and each has a LCD
Display module.
If we left the system in its default configuration of global, a fire
alarm in building A would cause both displays to show the
alarm. Consequently, someone in Building B could silence all
the alarms in Building A. This may not be a desirable situation.
However, we may want the drill switch on either panel to set
off the required annunciation devices in both buildings.
During the configuration and programming process we could
configure network routing for Cabinet 1’s LCD (located in
Building A) to receive changes of state only from cabinets 1, 2,
3, 4, and 5. Additionally, we would configure network routing
so that the Reset, Alarm Silence, Trouble Silence, and
Acknowledge switches on Cabinet 1’s LCD would affect only
cabinets 1, 2, 3, 4, and 5. The Drill function for the entire
system would be configured to activate from either Cabinet 1
or Cabinet 6 (all cabinets).

For Building B, Cabinet 6’s LCD display module would be
configured to receive changes of state from cabinets 6, 7, 8, 9,
and 10 only. We would specify that the Reset, Alarm Silence,
Trouble Silence and Message Acknowledge switches affect
only Cabinets 6, 7, 8, 9, and 10. Again, the drill function would
be activated from Cabinet 1 or Cabinet 6 (all cabinets).
In this way, an alarm or any other change of state would
affect and be displayed only in the building in which it
occurred. Furthermore, the Reset, Alarm Silence, Trouble
Silence, and Acknowledge Switches would be configured to
affect only their respective building’s cabinets. On the other
hand, if a fire drill were desired, pressing the switches on
either building LCD would result in a drill for both buildings.
Note: The EST3 also supports the configuration of alternate
network message routing for any object within its database.
