GAS ALARM
GAS ALARM
Placing of the sensor for
city and natural gas (methane CH4):
Mount the external sensor at a height of 15-30 cm
below the ceiling but no further than 4 m from the
gas appliance. Note that the sensor must be moun
-
ted above the highest door or window opening in the
room.
City and natural gas (methane) are lighter than air
and will therefore always rise.
Placing of the sensor for liquefied gas (propane
C3H8 / butane C4H10):
Mount the external sensor at a height of 15-30 cm
above the floor but no further than 4 m from the gas
appliance. Escaping liquefied gas is heavier than air
and sinks to the floor. It spreads across the floor rat
-
her like water - but as a gas - and always seeks the
lowest point.
The sensor may not be used in the following positions:
•
places where the sensor is shielded from escaping gas (e.g. behind curtains or in
cupboards)
•
directly above hearths or points of combustion or over a wash basin or sink
•
next to a door, windows, ventilator, fan, air conditioning unit etc.
•
in areas where dust or dirt can prevent the sensor from working
•
in areas at risk of explosion.
INSTALLATION
The GAS ALARM GX-B2pro is simply plugged into a 230V / 50Hz socket. The LED (Operate)
flashes green. The sensor of the monitoring system needs a warm-up time of 3-5 minutes
to achieve functionality. The LED (Operate) then lights up green and the GAS ALARM GX-
B2pro is ready for operation.
TEST button
The test button is for checking the LEDs and the acoustic alarm and does not test the sensor
itself. Please do not press the test button during the heating up period.
During the alarm, the alarm is muted with the TEST button and the LED (alarm) continues to
flash red until no gas is detected.
FAULT
In the event of a fault, the LED (error) flashes yellow, e.g. in the event of a cable break or
disconnected sensor. To rectify a fault, you must unplug the device, check the cable and
sensor and plug the device in again. The preheating time starts over. If you cannot find the
fault yourself, please contact Elektrotechnik Schabus.
