Gaseous Extinguishing System
Rev No. 1.3

Functional Testing
This section describes the system testing and commissioning procedures to ensure that the FT2GAS is
fully functional. All field wiring shall be terminated in FT2GAS control panel
except the gas release
circuit
3.3.1
FT2 System Test
3.3.1.1
Power Supply Check
Before applying any power to the system, ensure that the gas release circuit is replaced by a dummy
load. This load should be installed at the extinguishing gas equipment location
NOT
in the control panel.
It is recommended to use match head devices to simulate gas firing.
The voltage of each battery shall be measured, if the voltage is less than 10.7V, the battery shall be
replaced since it could have been deeply discharged or over its allowed life cycle.
•
Disconnect the battery leads to the battery terminals.
•
Turn ON the mains isolate switch and measure the voltage across the battery leads without
physical connection to the batteries.
•
The DC voltage shall be 27.3V – 27.6V (factory set). If the voltage is not within the specified
limits, adjust the trimpot of the switch mode power supply until the voltage becomes within 27.3-
27.6V.
•
Reconnect the batteries.
•
Only the green “Operation” LED and “Gas Fault” LED should be illuminated.
•
Press reset, only the “operation” LED would remain ON, any other indicators and the buzzer
must be OFF.
3.3.1.2
Alarm Test
1. Press the “Fire” test button of zone 1, the buzzer will sound and the fire LED illuminates steady
for approximately 3 seconds then turns OFF and the buzzer silences. No other LEDs shall be
illuminated.
2. Repeat step 1 for zone 2.
3. Use a smoke can to spray near a detector in the zone input (Alternatively, connect a 680
Ω
resistor to the respective zone inputs to simulate zone alarm). Check for the following
conditions:
a) Both indicators on the panel for Zone 1 “Fire” LED and Alarm Devices-Silence “Act.”
LED should flash once every 0.5 second.
b) “1
st
Alarm” LED flashes once every 0.5 second
c) “Fire Alarm” warning sign illuminates (it may flash, depending on the DIP switch
setting).
d) Audible Alert tone is activated (if Brooks sounder is used).
e) Press “Silence Buzzer” button, the buzzer should mute.
f) Press “Silence Alarm Devices” (if audible sounders are used) then press “Reset” to
reset the alarm.
Note:
Always push “RESET” after pushing “Alarm Devices-Silence”. This sequence
should be followed.
4. Repeat Step 3 for Zone 2 while zone 1 is inactive (i.e. no alarms) by pushing on “Disable button
under Zone 1.
