Smoke and heat detector installation
5.1
Smoke and heat detector installation locations
Install smoke detectors in the following areas:
–
bedrooms
–
living area(s)
–
all floors of a building, including basements
–
every 6.4 m (21 ft) of hallways and rooms
–
within 3 m (10 ft) of all bedroom doors
Install heat detectors in the following areas:
–
kitchens
–
garages
–
other places where smoke detectors are unsuitable
5.1.1
Locations to avoid
Do not place smoke detectors in the following areas:
–
Rooms where steam, condensation, normal smoke or fumes may trigger an alarm (e.g.
bathrooms, kitchens, garages). Keep at least 6 m (20 ft) away from sources of normal
smoke/fumes.
–
Very dusty or dirty areas as dust build-up in the chamber can impair performance (e.g.
garages). It can also block the insect screen mesh and prevent smoke from entering the
smoke detector chamber. If a smoke detector is installed in an environment exposed to
construction dust and dirt, cover the detector.
–
Insect infested areas. Small insects in the smoke detector chamber may cause
intermittent false alarms.
–
Areas where the normal temperature can exceed 100°F (38.7°C) or go below 40°F
(4.4°C).
–
Surfaces that are normally warmer or colder than the rest of the room (e.g. attic
hatches). Temperature differences might stop smoke from reaching the detector.
–
Adjacent to or above heaters or air conditioning vents, windows, wall vents etc.
Install smoke detectors in locations at least:
–
1 m (39 in) from dimmer controlled lights and wiring as some dimmers can cause
interference.
–
1.5 m (59 in) away from fluorescent light fittings as electrical noise and/ or flickering may
affect the detector.
5.1.2
Multi-story building
For buildings with more than one floor, install at least one detector on each level as shown
below.
