• There are no special requirements for
ceilings sloped at an angle of < 20°.
• In the case of ceilings sloped at an
angle of > 20°, detectors should be
installed 0.5–1 m away from the
highest point.
• The instructions for fully sloped ceilings
apply for partially sloped ceilings with a
horizontal ceiling surface measuring
< 1 m in width.
• In the case of partially sloped ceilings
with a horizontal ceiling surface
measuring > 1 m, detectors should be
installed in the centre of the horizontal

Choosing a location
The smoke alarm should not be installed in the following areas
• outside (use only in internal rooms);
• in areas in which the alarm can be triggered by disturbances (steam,
condensation, ‘normal’ smoke, fumes, dust, dirt or grease);
• next to ventilation or similar air inlets (draughts);
• in areas where temperatures may fall below 0° C or exceed 45° C.
