PoSSIBLE CAUSES FoR A FALSE ALARM

• Very intense cooking, water and/or
roasting vapours, air freshener,
perfume or insecticide sprays,
pollen, fine dust, dust from con-
struction or grinding work have
entered the unit.
• The smoke alarm is being affected
by extreme temperature fluctua-
tions or very strong electromag
netic radiation in immediate proxi-
mity to the unit.
• An alarm can only be activated by
cigarette smoke if the smoke enters
the unit directly or in very high
concentrations. The unit should be
protected from the abovemen-
tioned environmental conditions to
prevent a false alarm.
• one or more very small insects or
other small organisms have broken
through the unit's insect barriers.
This can be rectified by carefully
cleaning the unit with a vacuum
cleaner.
Always ensure that rooms are well
ventilated when you are cooking food
or when large amounts of water
vapour are being produced. A false
alarm can be stopped or prevented by
gently pressing the test and stop
button (IV) and thoroughly ventilating
the affected rooms.
Please notify your neighbours in the
event of a false alarm, as they might
otherwise mistakenly alarm the fire
brigade!
