be placed possible so that this is at least 50cm from the side wall and 61cm mounted away from
the corner of the room (see Figure 3).
Figure 3:
Mounting the smoke alarm detector on the ceiling
On ceiling beams, which are thicker than 20 cm, no installation of smoke alarm detector
should be done. A minimum distance of 50 cm is urgently recommended.
The smoke alarm detector should be mounted at least 50 cm away from lamps and
fluorescent lamps.
An installation height of 6m maximum should not be exceeded. If the installation height is
more than 6m, the smoke alarm detector must be installed on several levels.
The smoke alarm detector can supervise a maximum area of 60m².
The maximum distance of smoke alarm detectors in extensive corridors can be up to 15 m. To
the end side of corridors the smoke alarm detectors should be applied in the distance of
maximum 7. 5 m.
In small corridors and rooms which are not wider than 1m, the smoke alarm detector must be
mounted in the middle of the ceiling.
2.2 Rooms where no smoke alarm detector should be installed
Rooms which have a high air humidity - for example in the bathroom.
In garages or kitchens. A smoke alarm detector in the kitchen should only be installed, if the
distance to the stove is at least 4m.
Smoke alarm detectors should not be installed close to heaters, heating-, cooling- and
ventilation-shafts. Also, they may not be mounted on open fires or fireplaces.
In very dusty rooms.
With A-shaped roofs the smoke alarm detectors may not be mounted at the highest point.
Rooms having a room temperature of below 5 ° C or above 45 ° C.
In caravan or similar rooms. In these living areas, the attachment to the inside of parts are
advised. The air in the upper part of these areas as well as the ceiling is strongly warmed up
by intense solar irradiation. This can result that the strongly warmed up air keeps the smoke
from reaching to the smoke alarm detector.
