• For rooms with special room geometries (land-
ings, sloping roofs, corner rooms, etc.) further
installation regulations may apply. It is therefore
essential that you observe the following sections.
4.3.4 Corridors, small rooms and corner
rooms
If an increased number of false alarms is to be
expected (see
4.2. Reasons for false alarms
), wall
installation - as described in
4.3.8. Wall installa-
tion
- is to be preferred in corridors/rooms smaller
than 6 m² or kitchens that serve as escape routes.
Corridors and rooms with a width ≤ 1 m:
the ideal installation location is on the ceiling
centrally between the walls.
Corridors with a width ≤ 3 m:
• in corridors with a maximum width of 3 m, the
distance between two smoke detectors must not
exceed 15 m.
• The distance between the detector and the end
face of the corridor must not exceed 7.5 m.
• It should be noted that in corner and intersection
areas the smoke detector must be mounted in
the mitre line.
