4.  Introduction
Senator 25 Aspirating High
sensitivity Smoke Detector is
Designed to provide very Sensitive
Detection of Smoke. HSSD use a
Aspirating Fan to draw air from
Protected Area via Sampling Pipe.
Then the Sampled air is Passed
through a high sensitive detector
and Detector Analyses the sampled
air and generate a warning signal.
HSSD demands an external Power
Source. We use I/O card to connect
HSSD on Loop.

6. There are Three Types of Detector used in HSSD
*
 Light Scatter Detector
 Cloud Chamber Detector
 Particles Counting Detector

7. HSSD Work on Light
Scattering Principle. In
Normal Situation the
Sampling Air Continuous
Pass Through a Detection
Chamber in which IR Pulsed.
The IR rays Scattered by
Smoke Particles in Sample
Air. The Distortion in IR Rays
is Detected by IR Receiver.
The Scattered Rays
Proportional to the Level of
Solid Smoke Particles in
Sample Air.

9.  LED Indicator on HSSD
Three LED indicate
the current status
of HSSD .
1)Red = Fire
2)Yellow = Fault
3)Green = Normal

10.  Internal Parts of HSSD
1 ) Removable Terminal
Blocks
2 ) Dust Separator Filter
3 ) RS-232 Serial Port
4 ) Detector Addresses
Dip Switches
5 ) Addressable
Programmable
Interface card ( Relay
Card)
6 ) Internal Protection
Cover

11.  HSSD Terminal Block Connection
1)Fault Relay
Contacts
2)Fire Relay
Contacts
3)APIC Connection
Terminal
4)Sense Net
Connection
5)Power Connection
Terminal

13. The HSSD have Two Relay
Connection for Fire and
Faults.
Fire Alarm Relay NO (
Which Closes on Alarm.
Fault Relay NC ( Which
Open on any Fault I
Detector )
*
FIREFAULT

14.  Docking station or HSSD Base
We Install HSSD
on this Base.
