If the sensor is faulty then 3 short beeps will be emitted every 3 sec. and the red LED will blink.
Nuisance alarm:
Push the [TEST/HUSH] to silence the alarm for approx. 10 min. (See HUSH mode)
Low battery:
One beep signal every 40 seconds means the battery is almost empty. This signal is
transmitted to all interlinked alarms.
Remote low battery:
The battery of an interlinked smoke alarm is low. The sound indication is present in the
mode - 2 short beeps every 4 h. After removing the detector with the low battery from the base
sound indication on the other alarms will stop.
Chamber fault:
Three beep signals every 40 seconds mean a long term pollution of the smoke alarm as a result of
high dust concentration in the smoke chamber. In this case clean your smoke alarm of dust using a
vacuum cleaner. To avoid false alarming during cleaning remove the detector from the base.
Function test
When the smoke alarm is in the base press the Test button for at least 2-3 sec. If the device
operates properly the Alarm signal shall sound and the red LED shall flash every 0.5 sec.
Maintenance
The maintenance has to be carried out at least once a year as DIN14676 requires and should consist
of visual inspection, function test, and cleaning if necessary. The cleaning signal is 3 short beeps every 40
sec. (chamber fault mode).
To clean the smoke alarm apply a soft brush or a brush of your vacuum cleaner to remove dust and
spider web from side smoke entries.
Besides the maintenance described here you do not have to take any other actions to maintain the
device. Repairs should be carried out by the manufacturer if necessary.
All smoke detectors and especially optical devices are sensitive to ingress of dust and insects that
can cause false alarming. State-of-the-art ideas, materials and technological processes were used in
production of ASD-10QR to minimize influence of contamination. However it's not possible to
completely eliminate influence of dust and insects. To ensure durable lifetime of your smoke alarms
you should make sure that the alarm is clean and there is no dust accumulation there. All insects or
spider web in the immediate proximity from the device must be removed right away.
In rare occasions under certain circumstances, even when timely cleaning is provided, contamination
can be accumulated in the smoke chamber and cause the alarming. When it occurs the alarm should be
replaced. Contaminating substances are beyond the manufacturer's control as they are unpredictable
and are considered the natural deterioration.
