2. 2
This presentation is designed to give you a technical overview of the HCVR-3
Conventional Releasing control panel.
Always refer to the HCVR-3 Installation and Operation Manual for details
regarding the installation, programming, operation and servicing of the
Product (HA-06-294).
The HCVR-3 is a three-zone conventional releasing fire alarm control panel.
The HCVR-3 provides connections for Zones,
NACs, a Releasing Circuit, Relay Outputs and
more. Indicators and control buttons provide an
effective user interface to the system.
The HCVR-3 is UL 864, 9th Edition Listed.
Introduction

3. 3
There are various models of the HCVR-3 control panel:
o HCVR-3-R (115V)
o HCVR-3-R (230V)
o HCVR-3-C (115V)
o HCVR-3-C (230V)
HCVR-3 accessories include*:
 HCVR-SDU Status Display Unit
 HCVR-AS Abort Switch

Some additional features include:
 Cross-Zone operation for releasing verification
 Releasing Delay up to 60 seconds
 Abort function using the HCVR-AS Abort Switch
 Disable Zones function
 500mA of auxiliary power available
 1 amp of releasing power available
 1 amp of NAC power available on NACs 1 and 2
Additional Features
Diagnostic LEDs assist with troubleshooting.
Programming is easily and quickly accomplished using front panel controls.

5. 5
The HCVR-3 has three conventional zones and three NACs.
 NAC 3 is designed to indicate pre-release and release conditions. You will
only connect releasing notification appliances to this circuit.
This suggests that the HCVR-3 is intended for smaller areas and, ideally,
should be installed nearby where the extinguishing agent is to be discharged.
A Manual Release switch is located on the front of the HCVR-3.
System Planning

6. 6
If you are using cross-zoned smoke detectors for the purpose of automatic
releasing be aware of the following:
23.8.5.4.5 (NFPA 72, 2013 Edition) For systems that require the operation of two
automatic detectors to actuate public mode notification, the detectors shall be
installed at a linear spacing not more than 0.7 times the linear spacing determined
in accordance with Chapter 17.
90.19 (UL 864, 9th Edition) Units employing the multiple detector operation
described in 55.3.1 and 55.3.2 shall include guidelines for installing of a minimum
of two detectors in each protected space and to reduce the detector installation
spacing to 0.7 times the linear spacing in accordance with National Fire Alarm
Code, NFPA 72.
23.8.5.4.3 (NFPA 72, 2013 Edition) Systems that require the operation of two
automatic detectors to initiate the alarm response shall be permitted, provided
that the following conditions are satisfied:
(1) The systems are not prohibited by the authority having jurisdiction.
(2) At least two automatic detectors are in each protected space.
(3) The alarm verification feature is not used.
System Planning

7. 7
What does this mean to us?
1. You must install at least two detectors in the protected space (two
different zones of the HCVR-3 panel)
2. The detector spacing must be no more than 0.7 times the linear
spacing (if public mode notification is used).
System Planning

8. 8
 If you are using FireNET Xtinguish, additional codes and requirements
will be involved!
You must install the HCVR-3 in accordance with NFPA 72, NFPA 70 and all
local codes.
See Appendix C of the HCVR-3 I&O for battery and maximum wire length
calculations.
To comply with NFPA 72 and NFPA 2010 requirements, you must install a
supervised disconnect switch on the releasing circuit.
System Planning (almost done)
Do you need:
An Abort switch?
A Manual Release switch other than the one on the panel?

9. 9
The minimum required documentation (Chapter 7) includes the following:
 Written narrative providing intent and system description
 Riser diagram
 Floor plan layout showing location of all devices and control equipment
 Sequence of operation in either an input/output matrix or narrative form
 Equipment technical data sheets
 Battery calculations
 Voltage drop calculations (NACs and releasing circuit)
 And there is more…
System Planning (almost done)
Thorough planning is important.
It can help avoid problems later in the process.

10. 10
Section 3 of the HCVR-3 I&O explains the steps to install the panel.
To mount the panel, remove the fascia and securely mount the cabinet to the
wall.
Installation
Local codes may require that a licensed
electrician connect the AC power for you.
For convenience, the 24V DC terminal block is removable.
Next, connect the AC power, re-attach the
fascia, and make the other connections.
Use one of the knockouts on the left-hand
side of the enclosure for the AC power
wires.

11. 11
All circuits of the HCVR-3 Releasing Fire Control Panel are power limited
except the AC input circuit, transformer input and output, bridge rectifier
input and output, and the battery.
Installation
For proper operation and compliance with the National Electrical Code,
you must maintain a minimum ¼ inch spacing between power-limited
and non power-limited circuits.

12. 12
Installation
Two 7Ah sealed lead-acid batteries
provide standby power for the panel.
The batteries must be connected in
series, as shown here -
The panel should be mounted in a clean, dry area where it will not be subject
to shock or vibration.
The circuit board of the HCVR-3 is vulnerable to damage caused by
electrostatic discharge. Use a ground strap when handling the board to
prevent such damage.
Tip: Be sure the batteries are marked
with the date (month/year) of manufacture.

13. 13
Installation
The HCVR-3 has connections for the detection zones, supervised inputs,
NACs, releasing circuit, relay outputs, 24VDC aux power and status units
24VDC AUX Power
500 mA maximum
Remote Control Inputs
NOT USED
Status Units
For HCVR-3 accessories
NAC 1 and 2
Zones 1 - 3
NAC 3
1st / 2nd Stage relays
Supervised Inputs
EXTING Circuit
Relays

14. 14
Installation
The AUX 24V connection is a common special application output. The
output is supervised for short-circuits and ground faults. The output is not
supervised for open circuit conditions. Terminals of the Aux 24V
supply are labeled ( + ) and ROV. ROV is the negative terminal.
The AUX 24V supply is protected by an electronic, self resetting
fuse. Devices connected to this output must not draw current
in excess of 500 mA.
Status Unit terminals of the HCVR-3 panel contain connections for Data and
Power. The Data terminals provide RS485 communication.
The Power output of these terminals is designed to
operate the Status Unit and the Ancillary Board only.
A common earth ground is required between
all Status Units and the panel.

15. 15
Installation
The output of NACs 1 and 2 provide a steady voltage during alarm.
Listed NAC boosters may be used on NACs 1 and 2 as long as they operate
in the range of 18 – 28 VDC and draw less than 500 mA.
NAC 3 may only be used for releasing notification. The output is pulsing
during the delay phase, and continuous after the extinguishing agent has
been released.
Each NAC is terminated with a 10K ohm end of line resistor (EOLR).
Zones provide a nominal 24 VDC for
powering conventional two-wire
detectors. Each class B zone requires
a 6.8K ohm EOLR.
Zones may be configured Style B or Style C.

16. 16
Installation
The supervised inputs of the HCVR-3 are Class B Style C circuits*. The
inputs generally used are Abort and Manual Release.
This is the circuit configuration:
A 470 ohm trigger resistor
is installed in series with
the switch, as shown here.
For correct operation, the
supervised inputs must be
wired in this manner.
The relays are rated 30VDC @ 1 amp maximum.
*A Class B Style C circuit is no longer identified in NFPA 72. However, this circuit is still referenced in UL 864.

17. 17
Installation
Some additional facts:
The terminal blocks accept wire sizes from 14 to 18 AWG.
The AC fuse is 1.6 amp slow-blow. The battery fuse is 3.0 amp, slow-blow.
The maximum line impedance for the initiating circuits is 20 ohms. See
Appendix C for instructions on how to calculate the maximum wire length
for the NACs.
The maximum power supply current is 2.0 amps. You must manage the
available power to ensure that the total current draw of the system –
including the panel itself – does not exceed 2 amps.
The total resistance of the EXTING circuit must be no more than 9.7 ohms.

18. 18
Let’s take a look at the indicators on the HCVR-3 panel.
The manual refers to these as the ‘Upper Indicators’. Most of them are self-
explanatory.
Panel Indicators
If part of the system is disabled, the General Disablement LED will illuminate
along with an LED that describes what is disabled.
For example, if the EXTING output is disabled, the General Disablement and
Extinguishant LEDs will be illuminated.

19. 19
1st Stage Activated indicates that the first cross-zone is in alarm.
Panel Indicators
Release Imminent indicates that both cross-zones are in alarm and the panel
is preparing to release the extinguishing agent.
The Low Pressure LED is illuminated in response to the LOW P. SWITCH
input.

20. 20
When the key is set to Manual Only, the EXTING circuit will not operate in
response to alarms from the zones.
Panel Indicators
Additional information is contained in the HCVR-3 I&O manual.

21. 21
How about the lower indicators on the panel?
These indicators are all reasonably self-explanatory,
with the possible exception of “Tell Tale”.
Panel Indicators
When illuminated, this means that a manual release took place!
These provide greater detail about panel conditions. When the front door to
the panel is closed, these indicators are not visible.

22. 22
The Central Indicator is an LED display. It is used for programming
and to identify status conditions.
Panel Indicators
We will discuss this in greater
detail when we review
programming.
As with the indicators, there are upper, central and lower controls. The
upper and central controls are visible when the panel door is closed.

23. 23
The Mode, Select and Enter buttons are used for
level 2 and 3 configuration and programming.
Controls
Terminate Release – resets the EXTING circuit back to the non-alarm state.
There are five lower controls. These can only be seen when the front
door to the panel is open.
Note: Pressing the Reset button while the EXTING circuit is activated will not
cause the circuit to shut off. You must press the Terminate Release button if you
wish to shut off the activated EXTING circuit prior to the auto-shutoff time.
If you wait for the EXTING circuit to automatically shut off, the Reset button will
clear the alarm and return the panel to normal standby when pressed.
To illustrate…

24. 24
The zone alarms will be cleared when the Reset button is pressed.
Controls
If the Reset button is pressed anytime during “A”, the EXTING output will
remain on. It will automatically shut off at the end of the auto-shutoff time.
The Extinguishant Released, Release Imminent and 1st Stage Activated
indicators will remain illuminated. To clear them, press the Reset button
again anytime during “B” (after the EXTING output has shut off)

25. 25
All LED indicators will remain illuminated. Only the System Mode display will
clear.
Controls
If the Terminate Release button is pressed anytime during “A”, the EXTING
output will turn OFF immediately*.
Reset the panel to return it to normal condition.
* The Enable Access key does not need to be ON for the Terminate Release button to work.

26. 26
The Watchdog Reset button is used to clear a Watchdog event. These
events occur if the panel
fails to execute its
program properly. Such
events are uncommon.
Controls
EXTING. Mon. – used to calibrate the releasing circuit on the panel.
The Processor Reset button reboots the HCVR-3 processor. This button is
also used to clear the “Tell Tale” LED after a manual release event has
occurred.
Write Enable – used to access the programming options

27. 27
How do I calibrate the EXTING Releasing Circuit?
Controls
You should calibrate the EXTING circuit every time you install a HCVR-3 panel.
…and when should I do so?
1 – With everything connected to the EXTING circuit, does the panel
show a Releasing Trouble? If it does, turn the Exting Mon.
adjustment clockwise until the trouble clears.
2 – Disconnect the EXTING circuit wiring. Does the panel show a
Releasing Trouble? If it does not, turn the Exting Mon. adjustment
counter-clockwise until the trouble appears.
3 – Reconnect the circuit and turn the Exting Mon. adjustment one full turn clockwise.
Three easy steps:

28. 28
An HCVR-AS Abort Switch may be connected to the
ABORT input of the panel.
Other Installation Notes
As long as the Abort button is depressed, the countdown will remain at 10
seconds and the EXTING circuit will not activate.
When the releasing conditions have been satisfied and the panel is
counting down to activate the EXTING circuit, the Abort switch will halt the
countdown at 10 seconds.
If the button is released, the countdown will continue
from 10 seconds to 0. The button may not be used a
second time! To stop the release, the panel must be
reset before the 10-second timer expires!

29. 29
The Abort switch is a normally-open momentary push button.
Other Installation Notes
The connections on the switch look like this -
A 470 ohm trigger resistor must be used for the Abort circuit.
The circuit is wired like this - - - - - - - - - ->
The Status Display Unit also has connections
for an Abort switch. The circuit is labeled
“Hold”. You must use a
470 ohm trigger resistor,
as with the panel’s Abort
circuit.

30. 30
Other Installation Notes
The HCVR-3 panel already has a Manual Release switch.
All you have to do is pull the cover down and push
the button. No wiring or programming required.
For Manual Release stations, use the
MAN. RELEASE supervised input

31. 31
Other Installation Notes
The Manual Release circuit is
wired like the Abort circuit,
using a 470 ohm trigger resistor.
Here are two things to know about Manual Release:
1 – If abort is activated first, the manual release will override the abort function.
2 – If the manual release is activated first, the abort function will override the
manual release*.
* Activation delay must be enabled for the manual release, otherwise the release is immediate with no time to operate the abort switch.

32. 32
Other Installation Notes
NFPA 2010 requires a supervised disconnect switch. The purpose of this
switch is to prevent unwanted discharge of the system during maintenance.
The disconnect switch must electrically open the releasing circuit.
The HCVR-DS disconnect switch* may be used for this purpose. The switch
is wired into the EXTING circuit. When the switch is operated to disable the
circuit, the panel will indicate a trouble condition.
*Formerly SOM-R-DS

33. 33
Sequence of Operation
General sequence of operation*:
1 - One of the cross-zones goes into alarm.
* Operation may differ from this based on programming. There are several programmable options for the HCVR-3.
The Fire and Fire In Zone indicators will illuminate. NACs 1 & 2 will activate, as will
the relays. The 1st Stage Activated indicator will illuminate and the panel buzzer will
sound.
2 – The other cross-zone goes into alarm.
The Fire and (2) Fire In Zone indicators will illuminate. If the NACs had been
silenced they will resound. The Release Imminent indicator will illuminate and
relays will operate. The LED display will indicate the time remaining until release,
counting down to 0. NAC 3 will operate in a pulsing pattern to indicate the pre-
release condition. An Abort will halt the countdown at 10 seconds.
After the delay timer expires the EXTING circuit will activate. NAC 3 will change to a
continuous pattern. The Extinguishant Released indicator will be illuminated.

34. 34
Operation and Programming
Operating the HCVR-3
There are basically two access levels – Level 2 and Level 3.
Technically there are 3 access levels. Access
Level 1 allows you to use the Lamp Test and
Manual Release buttons. You may also use
remote Abort and Manual Release switches.
Level 2 allows some access to the controls and limited programming.
Level 3 allows full access to the controls and all programmable options.

35. 35
Operation and Programming
To enable Level 2, turn the Enable Access key to the right.
The display will show “Ad”. Like this:
The System Mode display will indicate
the function that is being set.
Let’s try an example…
You will use:
 The Mode button to move to the desired function;
 The Select button to scroll to the desired zone;
 The Enter button to select or de-select a function
Got it?
Uh…

36. 36

 The HCVR-3 manual says that it is “dE”.
Step 2 – find the code to disable the EXTING circuit.
Step 3 – Press the Mode button until the display shows dE
Step 4 – Press the Enter button. The dot on the display
indicates that this function is set. The panel will
indicate trouble as well.

38. 38
Operation and Programming
While we are on the subject of disabling the EXTING circuit…
NFPA does not allow this circuit to be disabled solely by software.
23.11.5.2 The disconnect (for the releasing circuit) shall be a physical switch and
not be accomplished by using software. (NFPA 72, 2013 Edition)
23.11.5.3 Software disconnects, even if activated by dedicated buttons or key
switches, shall not be permitted as a method to secure a suppression system from
inadvertent discharge. (NFPA 72, 2013 Edition)

39. 39

How about putting zone 3 in Test mode?
To cancel a function and return the panel to normal, simply select the
function and press the Enter button again so that the dot is not displayed.
 The code for this function is “t3”
Turn on the key and press Mode until you see “t1”.
Press Enter. Test mode is now active for zone 3.
Press the Select button until you see “t3”

40. 40
Operation and Programming
Let’s look at the programming options. How do we enable Level 3?
Let’s look at the programmable options…
Turn on the Enable Access key and slide the
Write Enable switch to the right.
The display will show “U##”. The number (##) indicates the number of
times that the level 3 configuration has changed.
You will use the Mode, Select and Enter buttons along with the System
Mode display to configure the programmable parameters.
The programming procedure is the same as setting the level 2 options.

41. 41
Operation and Programming
NAC Delay Time – sets a time delay before NACs operate. Only one may be
selected.
C00 = 30 seconds C05 = 5 minutes
C01 = 1 minute C06 = 6 minutes
C02 = 2 minutes C07 = 7 minutes
C03 = 3 minutes C08 = 8 minutes
C04 = 4 minutes C09 = 9 minutes
Note: delays are activated by the “Ad” option in Access Level 2.
For UL 864 9th Edition compliance, this setting may not be used.

42. 42
Operation and Programming
Coincidence detection options. Only one may be selected.
C11 – Zone 1 & Zone 2 starts the automatic release
C12 – Zone 2 & Zone 3 starts the automatic release
C13 – Zone 1 & Zone 3 starts the automatic release
C14 – Zone 1 & Zone 2 or Zone 2 & Zone 3 or Zone 1 & Zone 3 starts the

C21 – Disable Fire Buzzer (not permitted by UL 864, must be enabled)
C22 – Disable Fire Relay (not permitted by UL864, must be enabled)
C23 – Disable Trouble Relay
C24 – Disable Ground Fault (not permitted by UL 864, must be enabled)
C25 – Pulse R0V Output
C26 – Remove 24VDC aux power on system reset
C27 – Indicate “Extinguishant Released” when EXTING circuit is active

44. 44
Operation and Programming
C28 – No activation delay upon manual release
C29 – Release can be cleared by panel reset during imminent phase
C2A – Local Fire relay operates with Extinguishant Released indication
C2b – EXTING output on until panel is reset (no auto shutoff)
C2C – LOW P. SWITCH input uses N/C contacts

45. 45
Operation and Programming
C31 – Zone 1 alarm delay enabled
C32 – Zone 2 alarm delay enabled
C33 – Zone 3 alarm delay enabled
When the “Ad” option is set and the C31 – C33 options are set, the NACs (1
and 2) will follow the delay time set in C00 – C09.
Remember, UL does not allow delayed NAC operation!
For UL-compliant installations you may not use any of the
C31 – C33 options.

46. 46
Operation and Programming
C41 – Zone 1 pull station alarm delay enabled
C42 – Zone 2 pull station alarm delay enabled
C43 – Zone 3 pull station alarm delay enabled
These are similar to the C31 – C33 options. And they are not permitted for
UL compliance. Leave these options disabled.
C61 – Zone 1 operates through I.S. barrier
C62 – Zone 2 operates through I.S. barrier
C63 – Zone 3 operates through I.S. barrier
Not used. Leave these options disabled.

47. 47
Operation and Programming
C71 – Zone 1 short circuit causes an alarm
C72 – Zone 2 short circuit causes an alarm
C73 – Zone 3 short circuit causes an alarm
If these options are disabled a 470 ohm trigger resistor must be used with
the zone. A short-circuit will be indicated as a zone trouble.
If you find that the panel shows a trouble during alarm, check these options
to be sure that they are enabled.

48. 48
Operation and Programming
C81 – Zone 1 is non-latching
C82 – Zone 2 is non-latching
C83 – Zone 3 is non-latching
As you may have suspected, non-latching zone operation does not comply
with UL 864 9th Edition requirements.
Leave these options disabled (latching).
CA1 – Zone 1 input delay (30 seconds)
CA2 – Zone 2 input delay (30 seconds)
CA3 – Zone 3 input delay (30 seconds)
Do you think that UL will permit us to delay the indication of a fire alarm?
Leave these options disabled for UL 864 9th Edition compliance.

49. 49
Operation and Programming
These modes are accessed by pressing the Lamp Test button.
E00 – Panel can be reset immediately after discharge output has operated*
E01 – E30 – panel can be reset 1 to 30 minutes after discharge output has
operated.
* Note: auto-shutoff of the EXTING circuit will supersede this setting
-00 – No delay between alarm activation and EXTING circuit operation.
-05 to -60 – Delay time (in seconds) between alarm activation and EXTING
circuit operation. This is the time that will be seen on the panel display
during the Release imminent phase.
Use the Mode button to set the 10s and the
Select button to set the 5s.

50. 50
Operation and Programming
060 – Sets the duration time for the EXTING circuit to 60 seconds.
The C2b option must not be set to use EXTING duration time.
065 to 300 - Sets the duration time for the EXTING circuit. 5-second intervals.
That’s all of the programmable options for the panel.
As you probably noted, many of them may not be used for UL-compliant
systems. Here is a review of the options that you can use:
C11 – C19 Determine how automatic release is
started (cross-zone, all-zones, single-zone)
C23 Disable trouble relay
C25 Pulse R0V output
C26 Aux power is resettable
C27 Extinguishant Released LED operation
C28 Manual Release delay
C29 Panel reset possible during imminent phase
C2A Local fire relay operation
C2b EXTING output ON until reset
C2C LOW P. SWITCH is N/C
C71 – C73 Short circuit causes alarm
E00 – E30 Panel reset delay time
-00 – -60 Delay until release
060 – 300 EXTING circuit activation time

51. 51
Operation and Programming
After the programming is completed, be sure to move the Write Enable
switch back to the OFF position (to the left).
If you forget, the panel buzzer will sound and the General Trouble LED
will be illuminated.
Some Programming Tips:
Keep your eye on the dot!

52. 52
Operation and Programming
Record the configuration update count when finished programming.
Be sure that the EXTING circuit is disabled when
making and testing your programming changes!
This number changes each time L3
programming is changed.
Remember the HCVR-DS Disable Switch?

53. 53
Troubleshooting
First step is to test the system for proper operation.
Be sure that the EXTING disconnect switch is activated. Alternately,
you can disconnect the circuit at the panel and install the EOL diode
to clear the open circuit trouble.
 Confirm the proper operation of all inputs and outputs.
 Ensure that the EXTING circuit activates as expected.
 Check the operation of Abort and Manual Release switches.
Carefully follow all local and national requirements to check for proper
system operation.
The EXTING circuit uses an EOL diode (not used with FireNET Xtinguish)
The NACs use a 10K EOL resistor
All other supervised circuits use a 6.8K EOL resistor
Testing & Troubleshooting

54. 54
Troubleshooting
Problems such as low battery, ground fault and wiring trouble are indicated.
The diagnostic LEDs are an excellent troubleshooting tool.
If the Tell Tale LED is lit it means that the Manual Release was activated.
Be sure to clear this after the testing and user training is complete.
Most problems are quickly identified by using the indicators on the HCVR-3
panel.

55. 56
Maintenance
Chapter 14 of NFPA 72 (2013 Edition) provides direction on test frequency
and test methods that apply to the FACP and its devices.
Follow the inspection, testing and maintenance requirements of local and
national authorities.
The releasing system inspection, testing and maintenance will be covered by other standards.
Don’t forget to keep records of all inspections, testing and maintenance.
