entering the Smoke Alarm. Keep at least 0.30m away from
walls and corners (see figure 5).
4.2 Wall Mounting
When a ceiling position is not possible (for example on a ceil-
ing having exposed beams or joists, or built-in radiant heat-
ing) put the top edge of your Smoke Alarm between 0.15m
and 0.30m below the ceiling. Keep at least 0.30m from cor-
ners (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 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.
• Locate away from very dusty or dirty areas as dust build-up
in the chamber can make unit too sensitive and prone to
alarm.
