(c) On a sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke
Alarm 90 cm (3 feet) from the highest point measured
horizontally (see figure 5), because “dead air” at the apex may
prevent smoke from reaching the unit.
(d) Locations to Avoid
Don’t place your Smoke Alarm in any of the following areas:
•
Bathrooms, 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/34°F or above 40°C/104°F).
• 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, battery replacement etc).
• Locate unit at least 1.5m (5 feet) and route wiring at least 1m
(3 feet) away from
fluorescent light fittings
as electricial
“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. It can also block the insect screen mesh and prevent
smoke from entering the chamber.
• Do not locate in
insect infested areas
. Small insects getting
in to the chamber can cause intermittent alarms.
(e) Nuisance/False Alarms
If, when the alarm goes off, there is no sign of smoke heat or
noise to indicate that there is a fire, you should get your family
into a safe place, before you start investigating.
