b) Periodic monitoring
The function of the smoke detector is to be checked once a month.
To start the functioning test on the smoke detector, press the test button till an acoustic and visual
alarm is triggered.
If the acoustic signal sounds (3 * sound signal, brief pause , 3 * sound signal etc.) and
the LED flashes every 0,5 seconds, as long as the button is pressed, then smoke detector
is working properly; the battery state is in order.
Then release the test button again.
c) Status- and malfunction messages
• Normal operation (no alarm)
The indicator lights /LED flash briefly about every 32 seconds.
• Alarm/ Test alarm
The indicator lights /LED flashes every 0,5 seconds; the acoustic alarm is outputted (3 * sound
signal, pause, 3 * sound signal etc.).
• Battery change signal
Simultaneously (!) with the brief flashing of the indicator light (LED) a brief chirp signal sounds.
In this case, change all the batteries; see section "15. Replacing the battery".
• Sensitivity deteriorates
If a brief "chirp" signal sounds every about 32 seconds between the periodic lighting of the indicator
lights, then the sensitivity of the smoke measuring chamber has been restricted.
If this malfunction indication occurs, deactivate the smoke detector and change it.
d) Resetting alarm (e.g. on wrong alarm)
Briefly actuate the test button on the smoke detector. The alarm is terminated.
Eliminate the cause for the wrong alarm. Ventilate the room if, for example, if someone was smoking
