SOURCE OF ERROR MEASURE
Steam and moisture. False alarms can be triggered if the
smoke alarm is positioned too close to bathrooms or laundry
rooms, or in other places where the ambient humidity is high.
Position the smoke alarm at least 2 metres from bathrooms,
laundry rooms and other places where the ambient humidity
is high.
Dust and dirt.Astheairowsfreelythroughthedetection
chamber, the smoke alarm will attract a fair amount of dust and
pollenparticles.Thiscantriggerfalsealarms.Itcanalsomake
the smoke alarm more sensitive, which can likewise result in
false alarms.
Vacuum clean the smoke alarm regularly – use a plastic
mouthpiece so as not to damage the electronic components.
Make sure not to position the smoke alarm in highly dusty or
dirty places. Place a “cap” over the smoke alarm or remove
it completely if you are carrying out renovation work in your
home.
Draughts, dust and air ows. False alarms can be caused
by positioning the smoke alarm too close to doors, windows,
ventilation systems, fans, air ducts, heat pumps and the like.

Do not install smoke alarms in draughty places or close to
windows and doors, ventilation units, fans, air ducts, heat
pumps and the like. Find a more appropriate place for the
smokealarm,fartherawayfromdraughtsandairows.
Temperature variations can cause condensation to form in
the detection chamber. For example, if the smoke alarm is
placed in a room where windows are opened for ventilation in
the winter, close to exits, balcony doors or other places where
the temperature alternates between hot and cold.
Avoid installing smoke alarms in rooms where the
temperature changes rapidly, or close to doors and windows
that are often opened and closed. Move the smoke alarm to
a place witha more even, stable temperature.
