Installing The Detector; Choosing The Right Place - hager S151-22X Guide D'installation

Installing the detector

Make sure there is a distance of at least 2 meters between each product, except between two detectors.

Choosing the right place

The detector must be placed:
in rooms where there is a risk of fire (living
q
rooms with a fireplace, children's bedrooms,
lofts or basements that are occupied),
preferably at the center of the ceiling,
q
at a distance from ventilation grilles where
q
smoke might spread,
more than 50 cm away from obstacles
q
(walls, partitions, beams, etc.),
at either end of corridors more than 10 m
q
long.
If the smoke detector cannot be installed at a
horizontal ceiling, mount it:
more than 50 cm away from the corners of
q
the room (Fig. 1),
50 to 60 cm away from the ceiling (Fig. 1),
q
far away from potential sources of electri-
q
cal interference (electricity meter, metal cabi-
net, etc.),
if it is to be installed on a metal wall, insert
q
a shim made of non-magnetic material
(wood or plastic).
Installation examples:
Smoke detectors
The detector must not be placed:
directly on a metal surface,
q
near fluorescent tubes,
q
in very dusty rooms,
q
in rooms where the temperature could drop
q
below -10°C or rise above +55°C, as this will
prevent the detector from operating properly,
less than 1 m away from heating, cooling
q
or ventilation grilles likely to spread smoke,
less than 6 m away from a fireplace or
q
wood-burning stove where combustion
fumes could cause untimely alarms,
in premises where cooking fumes and
q
steam could result in untimely triggering,
in premises where there is a risk of con-
q
densation or humidity (bathrooms, laundries,
etc.),
at the top of pointed (A-shaped) ceilings as
q
an air pocket at this point could prevent
smoke from reaching the detector (Fig. 2).
