•
garages (exhaust emissions)
•
dusty and dirty rooms (measuring chamber gets dirty quickly or false
alarms are triggered)
•
in the vicinity of windows, ventilators, fans or any other locations
where the air moves around a lot
•
in the vicinity of areas where people smoke heavily (false alarms can
be triggered)
•
in the vicinity of solid steel beams, large metal surfaces, etc. as they
could significantly inhibit the transmission or receipt of the wireless
signal. Moving the alarm by just a few centimetres can often help.
6.2.1 Flat ceilings
The wireless 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.
“Installation on flat and pitched ceilings” on page 47).
The wireless smoke alarm may only be mounted to the ceiling.
Another type of installation, e.g. side wall mounting, is not
allowed.
6.2.2 Pitched ceiling
When mounting the wireless 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. “Marking
central bore hole” on page 48).
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.

6.3 Mounting the wireless smoke alarm
Following careful selection of the installation location, the ceiling bracket
has to be mounted first.
You can mount the wireless smoke alarm via
•
screw fastening with one central screw and plug,
•
screw fastening with two screws and plugs, e.g. for installation using a
standard installation box
to the ceiling.
If you have already taught-in the wireless smoke alarm to other
devices, please remove the ceiling bracket first. Press the
remove lever, turn the wireless smoke alarm anticlockwise and
pull it from the ceiling bracket.

Use a pen to mark the central bore hole position of the ceiling bracket
to the ceiling.
