5.1.1 Flat ceilings
The smoke alarm must be mounted on the ceiling in the centre of a
room. Keep a minimum distance of 50 cm to the walls and corners of the
room to avoid a build-up of air that stops the rising smoke (see „Fig. 5:
Installation on flat and pitched ceilings" on page 29).
The smoke alarm may only be mounted to the ceiling. Another
type of installation, e.g. side wall mounting, is not allowed.
5.1.2 Pitched ceiling
When mounting the smoke alarm in attic rooms with pitched roofs the
device must not be installed at the apex of the roof. If it is to be installed
on the pitched roof, it must be mounted around 1 m below the room's
highest point or, even better, on a (roof) beam (see „Fig. 5: Installation
on flat and pitched ceilings" on page 29).
The smoke alarm has to be installed horizontally in any case.
The installation on sloping ceilings is not allowed.
The wireless smoke alarm has to be installed horizontally in any
case. Contrary to DIN 14676 4.3.5.4, the installation on sloping
ceilings is not allowed.
