Smoke alarm FMR 4245
This Smoke alarm has been designed to provide an early warning in the event
of fire. As soon as smoke enters the device, an alarm is triggered. The device
does not detect flames. Many fires occur at night. As we have no sense of
smell while sleeping but wake up when we hear a noise, Smoke alarms are an
effective way of providing an early warning of the danger.
Field of application:
apartments, houses
Alarm signal:
acoustic signal with approx. 85 dB/3 m
Contact your local fire service or insurance company for information about what
to do in the event of fire. These establishments can provide you with relevant
leaflets underlining the importance of installing Smoke alarms.
Mounting location
For optimum protection of your home, install Smoke alarms in all rooms,
corridors, basements, cellars and store rooms. To ensure minimum protection
of your home, install one Smoke alarm in the corridor, one in the staircase on
each floor and one in each bedroom Fig. A. In flats with several apartments,
each family should install their own Smoke alarm.
• Do not install the detector in the bathroom or garage.
Only install it in the kitchen if it can be mounted at least 4 metres
away from the oven and similar heat sources.
• Do not install the detector in drafty areas, e.g. near a ventilator shaft
where the circulation of air could prevent the smoke from reaching
the detector.
• Do not install the detector in dusty environments or rooms
with high ambient humidity.
• Do not install the detector in the loft as, in the event of fire,
smoke-free air can accumulate in this area. In areas with roofs
which slope by more than 30° and which have a total ceiling height
of up to 6 m, observe a distance of 30-50 cm from the highest
point. On roofs which slope by less than 30°, mount the detector on
the pitched roof area Fig. B.
• Observe a minimum distance of 50 cm from walls, ceiling joints
(beams) Fig. C and lights Fig. D.
• Mount the detector in the centre of the ceiling, maintaining
a distance of at least 4 m from open fireplaces and ovens Fig. F.
• Several detectors need to be installed in rooms of over
60 m
2
and corridors measuring over 10 m.
Mounting/Operation
Fix the mounting plate to the ceiling using the screws and dowels provided
Fig. E. Connect the battery (provided) to the battery clip Fig. G1. The test key
LED (Fig. H1) will flash briefly approx. every 43 seconds to indicate that the
battery has been fitted correctly. Perform a function test (see Test/Maintenance).
Position the detector on the mounting plate and turn in a clockwise direction
until it clicks into place. The mounting lock (Fig. G2) prevents the detector from
being mounted if the battery is not fitted correctly.
Performance check/Maintenance
Press the test key (Fig. H2) until the alarm is enabled.
This tests correct operation of the smoke chamber, pulsating electronics and
battery. If everything is operating correctly, the alarm will be loud and pulsating.
Perform a test at least once a month and every time you replace the batteries.
The device automatically performs a test every 43 seconds. The LED Fig. H1
flashes briefly to indicate this. If the detector is faulty, the red LED will flash
approx. every 43 seconds alternately with the audible signal.
Note: The interval between each audible signal may be slightly longer than 43
seconds. To correct the fault, remove the batteries for 10 minutes. Reconnect
the battery and press the test key Fig. H2 until the alarm is activated. If this
does not correct the problem, replace the detector.
If the battery voltage falls below the minimum value, the detector will beep
approx. every 43 seconds and, simultaneously, the LED will flash for approx.
30 days to remind you to replace the batteries. When necessary (usually about
twice a year) wipe the device with a clean, dry cloth and clean with a vacuum
cleaner.
Additional notes
• Make sure the battery is fitted correctly.
• Always test the device after replacing the battery.
• The use of heat and Smoke alarms does not exempt you from your
obligation to insure your property.
• You may not hear the alarm if you are a deep sleeper or under the influence
of alcohol or drugs.
• We recommend that several detectors be used in rooms of over 60 m
corridors of over 10 m.
• Disposing of used batteries in household waste is strictly forbidden.
Dispose of batteries in shops with
recycling facilities.
• In the event of technical problems, contact the
manufacturer or your specialist dealer.
