5.3 False alarm, defect
The device has no indication of false alarm. If a false alarm still occurs, proceed as
follows:
1. Are the environmental conditions deviating from the optimum operating range,
or are chemicals other than the gases referred to herein, e.g. alcohol or
acid present in high concentration in the room, test the Gas detector 230 V in
another room.
2. If none of the above situations occur, disconnect the device from the power
supply and reconnect it.
If a false alarm continues, replace the device.
5.4 Test operation
Regularly test the device for function, e.g. once a week.
To do this, hold a commercial lighter without igniting near to the sensor
openings.
