Warning - renovation work, work in
the vicinity of the smoke detector
• Reinstall all correctly functioning smoke
detectors in their installation locations and
immediately replace any smoke detectors
that are no longer functioning correctly with
new devices.
• After installation, check all smoke detectors
for their function as described in
7.1. Testing
.
4.3 Installation locations and optimal
placement of smoke detectors
Note
The installation locations and positions of the
smoke detectors shown are only examples based
on average apartments and houses and are only
intended as a guide.
4.3.1 Not permitted installation locations
• Do not install smoke detectors in garages - the
combustion residues/exhaust gases produced
when starting a motor vehicle can trigger false
alarms.
• Unsuitable rooms are those in which temperatures
fall below 0°C or rise above 40° C or in which the
humidity is more than
93%.
• Do not attach the smoke detector e.g. to the
ceiling of a caravan or similar rooms. The sun's
rays heat the air quickly here, so that possible
smoke is thereby prevented from reaching the
smoke detector and triggering the alarm.
4.3.2 Installation locations with restrictions
• Also take into account the information in
4.2. Reasons for false alarms
.
• Smoke detectors must only be installed in kitchens
and wet rooms (bathrooms) if the restrictions
are observed and at the same time false alarms
caused by kitchen and water vapour can be
excluded.
• When installing the smoke detector near
dishwashers, washing machines, ovens, etc., keep
it at least 3 m away from these areas.
• When installing the smoke detector near ventila-
tion shafts or openings for heat and cold supply,
keep it at least 1 m away from these areas. The
air could blow the smoke away from the smoke
detector and thus interrupt or prevent the alarm.
Make sure that the air movement in such rooms
does not affect the penetration of
fi
re smoke into
the smoke detector.
• Perforated ceilings used for ventilation in forcibly
ventilated rooms must be closed within a radius
of 0.5 m around the smoke detector.
• In very dirty, dusty, greasy or insect-infested
areas, smoke detectors can become excessively
contaminated with dust and dirt, resulting in false
alarms or impaired smoke detection.
4.3.3 Standard rooms
• Smoke and combustion residues rise upwards
to the ceiling and then spread horizontally. The
ideal installation location is on the ceiling, in the
middle of the room.
• When installing, make sure that the smoke
detector is at least 0.5 m away from any side
wall and larger furnishings, e.g. high cupboards
(see Fig. 2a).
• A smoke detector is only permitted for room sizes
up to max
.
60 m
2.
If the room size exceeds 60 m
2
,
use additional smoke detectors. For example, at
least two smoke detectors should be installed in
rooms between 60 m² and 120 m² in size.
• A smoke detector is only approved for installation
heights up to max. 6 m. If the room height
exceeds 6 m, additional smoke detectors must be
installed at several levels.
