What to Do In Case of Alarm
There are 3 independent LEDs for each detector as fault, alarm and power LEDs. In addition
to them there are two alarms, one fault, one power and one battery LED used to monitor
overall panel status. ALARM1 and ALARM2 LEDs will be activated and kept active when any
of the detectors raised an alarm. The LEDs and related relay outputs will be active until
detector changes the alarm status and alarms acknowledged by user.
Checking Alarm and Fault Functions
The main board has 4 test buttons on top of each relay to generate false alarm and test relay
function. Relay functions can be tested by pressing to test buttons after completing cabling.
The relay will be activated while pressed the test button and deactivated when button
released.
Important:
Test buttons do not provide functionality to check that the control unit will
actually react at a specific gas concentration. This can only be achieved by applying a
calibration gas on the detector.
Please refer to the mandatory safety procedures (gas alarm) set forth by your safety
manager in case of any alarm. Here are few recommendations:
Keep calm and follow these instructions:
1.
Put out all naked flames (including cigarettes, pipes, etc.)
2.
Turn off all gas appliances.
3.
Turn off the gas supply at the tap and/or on the gas bottle (in the case of LPG).
4.
Do not switch electrical appliances, lamps or the gas detection control unit on or off.
5.
Open all windows and doors to air the room.
6.
Do not “reset” the control unit if it is in the same room.
If the gas concentration reading on the control unit does not fall below the level of alarm,
and the reason for the gas leak is not immediately apparent and/or cannot be repaired, quit
the premises and call the gas supplier and/or emergency services immediately to check the
installations and to make the premises safe and to possibly carry out the necessary repairs.
If the alarm stops and the reason for the alarm is identified and resolved (e.g. a kitchen
burner lit off but in the open position) the gas supply may be re-opened after checking that
all the gas appliances are off.
