4.3.6 Landings and galleries
If a room is divided in height, e.g. by a landing or
gallery, an additional smoke detector is required
below it if:
• both the area below the subdivision (landing,
gallery, etc.) is larger than 16 m²
• as well as length and width exceed 2 m each.
4.3.7 Rooms with joists/ beams
For rooms with beams or other joists, the following
specifications must be observed - depending on the
dimensions:
Joists / beams < 0.2 m:
If the joists / beams are lower than 0.2 m, they are
not relevant and should be considered as part of the
ceiling. The smoke detector can be installed on a
ceiling panel or directly on the joist/beam.
6 a
max. 0.2 m
Joists / beams > 0.2 m and area per ceiling
panel > 36 m²:
If the joists/beams are higher than 0.2 m and the
area of the individual ceiling panels is greater than
36 m² each, one smoke detector must be installed
per ceiling panel.

Note
• Make sure that the smoke detector(s) to
be installed is/are nevertheless mounted as
centrally as possible in the respective area
(entire ceiling/ceiling panel).
• Furthermore, it should be noted that one smoke
detector is required for each area of max. 60 m².
4.4 Installing the base plate
• Hold the base plate of the smoke detector at the
installation location - the two mounting holes serve
as a template for marking the drill holes.
Warning
Before drilling and installing, make sure that there
are no electrical lines, water, gas or other lines in
the area of the installation location.
• On a wooden ceiling or beam, drill approx.
20 mm deep with a 2.5 mm drill bit. Use the
enclosed screws without plugs.
• For concrete or masonry, use a max. 5 mm drill
bit (measure the plugs included beforehand) and
pre-drill approx. 25-30 mm deep to be able to
insert the plugs.
• Insert the plugs (concrete or masonry).
• Fix the base plate of the smoke detector with the
enclosed screws.
