Gas Extinguishing System Test
1. Simulate the actual alarm test in either one of the two zones following steps 3a) to 3d) under the
“Alarm Test” in section 3.3.1.2 page 26 and check the following:
•
The “Fire” LED of the tested zone, “Silence Alarm Devices Act.” and “1
st
Alarm” LED should
illuminate.
•
“Fire Alarm” signs and audible alert tone (if used) should activate if configured via the DIP
switch (SW1) located on the Warning Signs Circuit Board (PCB291R1/SUB937). Refer to
area D2 in the Warning Signs Circuit Board layout in section 4.1.3 on page 33.
2. Continuing from step 3d), to simulate actual alarm test on the other zone, check for the following:
•
The “Fire” LED of the zone under test and “2
nd
Alarm-Timer Running” LED should both
illuminate.
•
Gas release timer will be running for the time delay set by the 8 way DIP switch SW1 on
the gas board control board (SUB928).
•
“DO NOT ENTER” and “EVACUATE” signs will activate.
•
Audible Evac tone will activate (if used).
•
When the timer times out, the “Gas Initiated” LED illuminates and gas will release.
•
Gas discharge confirmation via gas discharged input will illuminate the “Gas Discharged”
blue LED if the Gas Discharge input is simulated to be active.
•
Press “Silence Alarm Devices” button then press the “Reset” button.
3. Repeat step 3 and press the “Service Master Abort” switch before the timer times out, check the
following:
•
“Service Master Abort” LED and “Gas Disabled LED” illuminate.
•
The Gas is not released i.e. the “Gas Initiated” LED should never illuminate.
•
Press “Silence Alarm Devices” button then press the “Reset” button.
3.3.3
Local Control Station (LCS) Test
1. Lift up the MCP cover then press the “Gas Release” switch, check the following:
•
The LED integrated in the MCP switch illuminates.
•
The “2
nd
Alarm-Timer Running” LED illuminates.
•
“Gas Externally Released” LED illuminates.
•
Gas release timer starts running for a time delay set by the DIP switch.
•
“DO NOT ENTER” and “EVACUATE” signs will illuminate
•
Audible Evac tone will activate (if used).
•
When the timer times out, the “Gas Initiated” LED illuminates and the gas releases.
•
Gas discharge confirmation via gas discharged input will illuminate the “Gas Discharged”
blue LED if the input is simulated to be active.
•
Using a small screw driver, lift up the MCP button to mechanically reset the switch
