CAUSES AND REMEDIES FOR FALSE ALARMS
A smoke alarm device detects and reacts to smoke particles in the air. The smoke particles set o the
smoke alarm device. This function means that the smoke alarm device will also react to dust particles,
moisture or other particles in the form of pollen, insects and so on. These factors are usually the cause of a
false alarm.
CAUSE OF ERROR ACTION
Steam and moisture. A false alarm may occur if the smoke alarm device is
placed too close to a bathroom, laundry room, or other location with high
air humidity.
Place the smoke alarm device at least 2 metres from any bathroom, laund-
ry room, or other location where high air humidity may occur.
Dust and dirt. Since air passes freely through the detection chamber, the
smoke alarm will always attract some dust and pollen particles. This can
lead to a false alarm. The smoke alarm device may also become more
sensitive for this reason, which could cause false alarms. In addition, dirt
will collect over time, as the smoke alarm device ages, which may result in
false alarms.
Regularly vacuum the smoke alarm device , using a plastic nozzle to avoid
damaging the electronics. Avoid fitting smoke alarm devices in places with
a lot of dust and dirt. You can put a ‘hat’ over the smoke alarm device or
remove it entirely while you are carrying out renovation work at home that
involves sawing, sanding, etc.
Draughts, dust and air flows. False alarms may be caused by the smoke
alarm being placed too close to doors, windows, ventilation systems, fans,
air ducts, heat pumps or suchlike. This can lead to dust particles being
carried up into the detection chamber.
Do not install smoke alarm devices in a draughty location, close to windows
or doors, ventilation, fans, air ducts, heat pumps or suchlike. Find a better
location for the smoke alarm device, further away from draughts and air
flows.
Temperature variations. Temperature variations may lead to condensation
in the detection chamber. This may happen, for example, if the smoke
alarm device is placed in a room where windows are opened for ventilation
in the winter, or close to exits, balcony doors or other places that switch
between hot and cold.
Avoid fitting smoke alarm devices in rooms with rapid temperature
changes or close to windows and doors that are frequently opened and
closed. Move the smoke alarm device to a place with a more even and
stable temperature.
Generally unfavourable positions. Incorrect positioning in an unstable
indoor environment, a draughty area, close to electronic apparatus (EMC)
and lighting may cause a false alarm.
Place smoke alarm devices at least 5 metres from open fires, stoves or
other heating devices; 2 metres from ventilation ducts, heat pumps and air
conditioning; 1 metre from light bulbs and fluorescent tubes.
