Alarm in the event of a gas leak
The gas alarm detects a gas leak with the sensor.
If the concentration of gas at the sensor exceeds
the pre-set sensitivity threshold on the gas alarm,
the alarm responds: the red ALARM LED
flashes and the loud alarm signal is emitted.
The alarm continues until the gas concentration
falls back to below the pre-set sensitivity level.
Follow the instructions in the section
„What to do in the event of a gas leak"

tivity threshold, the alarm responds: the
red ALARM LED
alarm signal is emitted.
