Mounting the heat detector
on the ceiling ≤ 1m
Note:
If you are unsure about the mounting of the heat detector in your rooms, please advised
by a qualified electrician!
The heat detector must be installed on the ceiling in the middle of the room, because heat rises to
the ceiling of the room and spread horizontally. The heat detector should be placed possible so
that this is at least 50cm from the side wall and 60cm mounted away from the corner of the room.
If you attach the heat detector to the wall, attach it approx. 30cm from the ceiling (
see Figure 3
).
Figure 3:
Mounting the heat detector on the ceiling or wall
On ceiling beams, which are thicker than 20 cm, no installation of heat detector should be
done. A minimum distance of 50 cm is urgently recommended.
The heat 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 heat detector must be installed on several levels.
The heat detector can supervise a maximum area of 60m².
The maximum distance of heat detectors in extensive corridors can be up to 15 m. To the end
side of corridors the heat detectors should be applied in the distance of maximum 7. 5 m.
In small corridors and rooms which are not wider than 1m, the heat detector must be mounted
in the middle of the ceiling.
2.2 Rooms where no heat detector should be installed
A heat detector in the kitchen should only be installed, if the distance to the stove is at least
4m.
Heat detectors should not be installed close to heaters, heating-, cooling- and ventilation-
shafts. Also, they may not be mounted on open fires or fireplaces.
Do not install a heat detector in the immediate vicinity of doors and windows!
With A-shaped roofs the heat detectors may not be mounted at the highest point.
Rooms having a room temperature of below above 50 ° C.
