light fitting or decorative object which might obstruct smoke
entering the Smoke Alarm. Keep at least 0.3m away from
walls and corners (see figure 5).
4.2 Wall Mounting
When a ceiling position is not practical (for example on a
ceiling having exposed beams or joists, or built-in radiant
heating) put the top edge of your Smoke Alarm between 15
and 30 cm below the ceiling. Keep at least 0.3m from corners.
(see figure 5).
4.3 On a sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke
Alarm 0.90m from the highest point measured horizontally
(see figure 6), because “dead air” at the apex may prevent
smoke from reaching the unit.
4.4 Locations to Avoid
Don’t place your Smoke Alarm in any of the following areas:
• Bathrooms, kitchen, shower rooms, garages or other
rooms where the smoke alarm may be triggered by steam,
condensation, normal smoke or fumes.
• Attics (uninsulated) or other places where extremes of
temperature may occur (below 4°C or above 40°C).
• Near a decorative object, door, light fitting, window
molding etc., that may prevent smoke from entering the
Smoke Alarm.
• Surfaces that are normally warmer or colder than the rest
of the room (for example attic hatches, uninsulated exterior
walls etc). Temperature differences might stop smoke from
reaching the unit.
• 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 awkward areas where it may be difficult to
reach the alarm for testing or battery replacement.
• Locate unit at least 1.5m away from fluorescent light
fittings as electrical “noise” and/or flickering may affect the unit.
