7.8 Gas alarm system (special equipment)
The gas alarm system has two functions:
z Alarm in the case of an attack with narcotic gas
z Alarm if there is a leak in the gas system
The gas alarm system is ready for operation as soon as the 12 V power supply
is supplied with power.
The flashing LED (Fig. 125,2) next to the terminal block of the gas sensor
(Fig. 125,1) indicates readiness for operation.
Switching off the buzzer:
Briefly switch off the 12 V power supply and switch it on again (e.g. on the
safety cut-out in the power pack).
Z If the gas sensor or a cable is defective, the buzzer sounds until the defect
has been rectified.
Z If a deodorant spray, hairspray or a powerful cleaning agent is used in the
immediate vicinity of the gas sensor, a false alarm may be triggered.
Extended time in a tunnel (traffic jam) may also trigger a false alarm.
Z Also read the manufacturer's instruction manual.
