CAUSE OF ERROR ACTION
Steam and moisture. A false alarm may occur if the smoke
alarm is placed too close to a bathroom, laundry room, or
other location with high air humidity. Place the smoke alarm at least 2 metres from any
bathroom, laundry 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 may also become more sensitive for this
reason, which could cause false alarms. In addition, dirt
will collect over time, as the smoke alarm ages, which may
result in false alarms. Regularly vacuum the smoke alarm, using a plastic nozzle
to avoid damaging the electronics. Avoid fitting smoke
alarms in places with a lot of dust and dirt. You can put a
‘hat’ over the smoke alarm 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 alarms 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,
further away from draughts and air flows.
Temperature variations. Temperature variations may lead
to condensation in the detection chamber. This may hap-
pen, for example, if the smoke alarm 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 alarms in rooms with rapid tempe-
rature changes or close to windows and doors that are
frequently opened and closed. Move the smoke alarm 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 alarms 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.
CAUSES AND REMEDIES FOR FALSE ALARMS
This smoke alarm detects and reacts to smoke particles in the air. The smoke particles sets off the smoke
alarm. This function means that the smoke alarm 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. If the alarm does
sound, check for fire first. If a fire is discovered, escape quickly and call the Fire Department. If no fire is pre-
sent, check to see if one of the reasons listed below may have caused the alarm.
