Wall mounting
If ceiling mounting is impractical, smoke alarms may be mounted on a wall, provided that:
1 The top of the smoke alarm is between 150 mm (6") and 305 mm (12") below
the ceiling.
2 The bottom of the smoke alarm is above the level of any door openings.
Wall mounting should only be considered where closely spaced beams or similar
obstructions may preclude ceiling mounting. It is considered to be the responsibility
of the installer/client to determine if the presence of asbestos in the ceiling material
would make ceiling mounting 'impractical' .
On a sloping ceiling
With a sloping or peaked ceiling, install a smoke alarm within 610 mm (24") of the peak,
measured vertically. If this height is less than 610 mm (24"), the ceiling is regarded as
being flat, see Figure 4.

Locations to avoid
DON'T place smoke alarms in any of the following areas:
Bathrooms, kitchens, shower rooms, garages or other rooms where the smoke alarm
may be triggered by steam, condensation, normal smoke or fumes. Keep at least 6
meters (20 ft) away from sources of normal smoke/fumes.
Locate away from very dusty or dirty areas as dust build-up in the chamber can im-
pair performance. It can also block the insect screen mesh and prevent smoke from
entering the smoke detector chamber.
Do not locate in insect infested areas. Small insects getting into the smoke detector
chamber can cause intermittent alarms.
Places where the normal can exceed 104 °F (40 °C) or be below 32°F (0 °C) (e.g.
attics, furnace rooms, directly above ovens or kettles etc.) as the steam could cause
nuisance alarms.
Near a decorative object, door, light fitting, window moulding etc., that may prevent
smoke from entering the smoke alarm.
Apex
Apex
Surfaces that are normally warmer or colder than the rest of the room (e.g. attic ac-
cess). Temperature differences might stop smoke from reaching the alarm.
Next to or directly above heaters or air conditioning vents, windows, wall vents etc.
that can change the direction of airflow.
In very high or confined areas (e.g. over stairwells) where it may be difficult to reach
the alarm (for testing, hushing or battery replacement).
Locate the alarm at least 900 mm (3 ft) from dimmer controlled lights and wiring as
some dimmers can cause interference.
Locate alarm at least 1.5 m (5 ft) and route wiring at least 1 m away from fluorescent
light fixtures as electrical "noise" and/or flickering may affect the unit.
