Choosing The Best Place To Install The Detector - DAITEM SH151AX 3 Manual De Instalación

2.3 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.). The detector can also be installed in areas with a harsh or difficult environment
such as kitchens (cooking fumes), garages (smoky atmosphere), and other uninhabited areas that
are often dusty as long as the smoke detection function is deactivated (see chapter 2.2) (Fig. A),
• preferably in the centre of the ceiling,
• far away from fan vents likely to spread smoke or heat,
• 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 (except if the smoke detection function is deactivated, see chapter 2.2),
• 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 (unless the smoke detection function is deactivated, see chapter 2.3),
• in an area where cooking fumes and water vapour might cause unwanted triggering (unless the
smoke detection function is deactivated, see chapter 2.2),
• in a room where there might be condensation or damp (do not use in bathrooms, laundries, etc.)
• at the centre of a pointed ceiling (A-shaped), as the air pocket located here can prevent smoke from
reaching the detector (Fig. C),
• directly on to a metal wall: use a non-magnetic spacer (wooden or plastic).
