Operation:

• In areas where ventilation and/or air conditioning systems are used is must be ensured that air movement does not affect the function of the smoke detector.

• Smoke detectors must be permanently fixed on the ceiling. Mounting instructions must be observed.

• Choose a mounting method that ensures a holding force of at least 20N in vertical direction.

• The smoke detector is designed for monitoring residential buildings or residential premises (not for industrial or commercial usage).

• A function test must be performed on each smoke detector after installation.

• The functionality of each installed smoke detector must be regularly checked and maintenance measures must be ensured. Perform function test 1 per week, clean every 3 months.

• Smoke detectors must be taken out of service at the latest after 10 years and replaced with a new device.

Mounting locations

Mounting locations for smoke detectors:

• Bedrooms, children’s rooms and corridors must be equipped (basic requirement) with smoke detec- tors.

• Always on the ceiling.

• 50 cm from the wall (or beam).

• If the room is subdivided by ceiling-high furniture etc., a smoke detector must be installed in each room partition.

• In rooms with a floor area ≤60m2, divided into ceiling boxes by beams or joists, the following ap- plies:

o In ceiling boxes bigger > 36m2 a smoke detector must be installed per ceiling box (see Fig- ure 1a).

o In ceiling boxes ≤36m2 and with ceiling slopes ≤20°as well as beams or joists with a height

≤0.2m, the individual ceiling boxes are not taken into account (see Fig 1.b). Install smoke detectors as centrally as possible in the room, in a ceiling box or on the joist.

o In these rooms have beams or ceiling joists with a height >0,2m, the smoke detector must be installed on a beam or girder, as centrally as possible in the room (see Fig c).

• In rooms with a floor area of >60m2, an additional smoke detector must be installed per 60m2.
