2.1. Choosing the best place to install the detector
The detector must be placed:
• in rooms where there is a fire hazard (living rooms with fireplace, children’s
bedrooms, occupied lofts or basements, etc.) (Fig. A),
• preferably in the centre of the ceiling,
• far away from fan vents likely to spread smoke,
• more than 50 cm away from any obstacles (walls, partitions, beams, etc.) (Fig. B),
• at each end of corridors if they are longer than 10 m.
If the detector cannot be installed horizontally on the ceiling, fix it:
• at a distance of 40 to 50 cm from the ceiling (Fig. B),
• far away from any sources of electrical disturbance (electricity meter, metal cabinet,
electronic ballast, etc.).
The detector must not be placed:
• close to an electronic ballast, low voltage transformer, energy saving light bulbs,
fluorescent tubes, etc. (minimum distance: 50 cm),
• in excessively dusty rooms,
• in a room where the temperature might drop below -10°C or rise above +65°C,
which would prevent the detector from operating properly,
• at least 1 m away from heating, cooling or air circulation vents likely to disseminate
smoke or heat,
• at least 6 m away from a fireplace or wood burning stove where the smoke from
combustion might trigger an unnecessary alarm,
• in an area where cooking fumes and water vapour might cause unwanted triggering,
2. Installation
the detector comes ready powered. Simply lock it on to its base (step 4.
Chapter 2.2. Installing the detector as a standalone device) to put it in
normal operating mode.
