BATTERY RESERVE ALARM

If a simple, short signal tone (peep)
is sounded every approx. 90
seconds, this means that it has
reached its battery reserves. If a
double, short signal tone (peep-
peep) is sounded every approx. 90
seconds, this means that the
device is not capable anymore of
compensating for soiling of the
detection optics. Each signal tone
can be temporarily (24 hours)
deactivated by pressing the test
and stop button (fi g. - IV.). If the
smoke alarm device sounds one of
the two previously described signal
tones, the device can function as a
warning device for a maximum of
60 days, and for this reason it is
important to replace it before the
remaining 60 days expire!

ALARM

frying vapours or room, perfume
and insect sprays, pollen, fi ne dust
or dust from construction or
sanding have found their way
directly into the device.
• Extreme temperature fl uctuations
or very strong electromagnetic
radiation are present directly
nearby the smoke alarm device.
• Cigarette smoke only triggers an
alarm if the smoke fi nds its way into
the smoke alarm device from very
close by or in very high
concentrations.
• The device should be protected
against the infl uences in the
environment named here in order
to prevent the smoke alarm device
from giving a false alarm.
When cooking or in the case of
heavy water vapour generation
near the smoke alarm device, care
must always be taken to ensure
good ventilation of the rooms. A
false alarm can be
remedied, or hindered, by a soft
