3.10 Gaseous Extinguishing Control Module
3.10.1
Overview
The Gaseous Extinguishing System Control Module is provided for use as an option in FT420
15
. The
gas module is comprised of the following:
•
Control Board SUB928, software is configured to interface with CIE
•
Display Board SUB929
•
CIE interface board SUB943
•
Front panel decal with interconnection cable
In addition to the control module, system ancillaries may include:
•
A combination of Brooks Warning Signs
•
Brooks Local Control Station (LCS)
•
Voice / Tone Electronic sounder
•
Dual Strobe Module
The Gas Control Module combined with other Brooks system components have been designed to
provide monitoring and control functions of a complete gaseous extinguishing system that meets the
requirements of clause 7.1 to 7.16 of the Australian Standard AS4214-2002 (including amendment 1).
For more details, refer to FT2GAS Operation / Technical Manual MA400.
The Gas Control Module have the following inputs / outputs:
•
Three fully supervised external input circuits, Gas Lock-Off Valve input, Manual Release input
and Gas Discharged Sensor input.
•
Fully Supervised System Inoperative Warning Sign 24V
DC
output rated @ 0.5A maximum.
•
Fully supervised 2 wire system, 24V
DC
output for level 1 and level 2 alarm to Brooks Warning
Signs (alarm 1 [+/-] & alarm 2 [-/+]) rated @ 3A maximum.
•
Fully Supervised 24V
DC
Gas Release output rated @ 5A maximum.
•
Gas Release Clean-Contact Relay output rated @ 2A maximum.
•
Gas Fault Clean-Contact Relay output rated @ 2A maximum.
•
Gas Isolate Clean-Contact Relay output rated @ 2A maximum.
•
One four-wire Local Control Station (LCS) interface. Both the local gas isolate control and the
Local Gas Release Control are fully supervised for open and short circuit faults.
•
Adjustable gas release timer via a built-in DIP switch.
Note:
The current rating above is the maximum current capacity of the outputs, a power supply
calculation must be performed to ensure that the power supply capacity is sufficient to run the system
in full alarm condition without exceeding the maximum current rating of the power supply.

In FT420 software V2.3 and higher, zone 1 and zone 2 in FT420 are allocated for the 1
st
and 2
nd
alarm in the gaseous
extinguishing system.
