Note
• Test the smoke detector
ONLY
using the
TEST
button. Never use an open flame, lighters, etc.
to simulate an alarm and test the function.
7.2 Replacing the battery / smoke detector
The operating life of the included 9V battery (type
6F22) is at least one year. If the battery is weak,
a signal tone sounds every 32 seconds. The
LED
continues to flash every 32 seconds.
The low battery indication is given for at least
30 days.
During this time, the smoke detector can normally
still detect smoke. Make sure
you replace the battery without delay!
• Turn the smoke detector counterclockwise to
remove it from the base plate.
• Remove the spent battery, disconnect it from the
battery connection, connect a new
• battery observing the correct polarity to the
battery connection and insert this into the battery
compartment (see Figure 5).
• When functioning properly, the
LED
flashes briefly
approx. every 32 seconds.
• Now carry out the assembly and function check
- as described in
5.2. Installing the smoke
detector
.
Note
In addition to the life of the battery, the life of
the smoke detector (especially the sensor) is also
limited in time. Therefore, before installing the
smoke detector, observe the date printed on it for
replacement. Replace the smoke detector with
a new unit on this recommended date, even if
there is no indication of a low battery yet. Only
use batteries of type 6F22 (zinc-carbon) or 6LR61
(alkaline)!
7.3 Care
Clean the smoke detector regularly (at least once a
month) to remove dust, dirt and debris.
Use a hoover with a soft brush and carefully vacuum
all sides and covers of the smoke detector.
Make sure that the smoke detector does not have
any function-relevant damage (e.g. cracks in the
housing). If this is the case, replace the smoke
detector with a new device.
Ensure that all speci
fi
cations are met according
to the installation location (see
4. Installation
).
In the event of structural/recognisable changes,
check whether the existing installation of the smoke
detector device still meets all relevant requirements.
If necessary, adjust the installation accordingly.
Warning
• Check each smoke detector that you dismantle
(see
7.4. Dismantling the smoke detector
)
and reinstall or install in a different place for
its function as described in
7.1. Test / alarm
situation
.
• Immediately replace smoke detectors that no
longer function correctly with new devices.
