Where not to install your smoke & heat detector
A false alarm can be triggered if smoke & heat detectors are installed where they cannot function
properly. To prevent such false alarms, do not install smoke & heat detectors as follows:

In areas with constant fresh air supply. Movement of fresh air can keep
smoke from entering the smoke & heat detector, thereby limiting its
effectiveness.

Near paint thinner vapors.

In very hot or cold areas, such as near air conditioners, heaters or fans.

In areas with still air, such as under pointed roofs or in corners between
walls and ceiling. Still air can prevent smoke from reaching the detector (see
Figure 3 and Figure 4 for recommended installation locations).

Areas prone to insects. If insects enter the sensor chamber of a detector, they
can trigger false alarms. If you have a bug problem, take care of it before
you install detectors.

Near fluorescent lights, since electromagnetic fields from fluorescent
lighting can trigger false alarms. Install smoke & heat detectors at least 1.5m
from such lights.
Where the "heat only" mode can be used
To prevent false alarms, you can use your detector in "heat only" mode. Use the detector
in this mode only in or near areas where typically only harmless combustion particles
exist which do not present a fire hazard. If the distance of the detector to places at which
combustion particles normally exist – for example in kitchens – is less than 6 meters,
install the detector as a heat detector only and as far away from the combustion particles
as possible.
To prevent false alarms, make sure the ventilation in such places is good. Never try to
prevent false alarms by switching off the detector.
Other locations:

In damp or humid areas or near bathrooms with showers. The humidity in
the air can get into the measuring chamber and form droplets as it cools,
which can then trigger false alarms.
