the dining room. You should also consider putting smoke alarms in any bedrooms where
fires might occur, for instance, where there is an electrical appliance such as an electric
blanket or heater, or where the occupant is a smoker. You could also consider putting smoke
alarms in any rooms where the occupant is unable to respond very well to a fire starting in
the room, such as an elderly or sick person or a very young child.
Checking alarms can be heard
With the alarms sounding in their intended locations check that the alarm can be heard
in each bedroom with the door closed, above the sound of any TV/audio systems. The TV/
audio systems should be set to a reasonably loud conversation level. If you cannot hear the
alarm over the sound of the TV/audio system, the chances are it would not wake you. Con-
necting the smoke alarms to one or several Visit receivers will help to ensure that the alarm
is noticed throughout the property.
Positioning
On a ceiling
Hot smoke rises and spreads out, so a central ceiling position is the recommended location.
The air is "dead" and does not move in corners, therefore smoke alarms must be mounted
away from corners. Place the unit at least 0.5 m from any light fitting or decorative object
which might obstruct smoke entering the smoke alarm. Keep at least 0.5 m away from walls
and corners, see Figure 4.
On a sloping ceiling
In areas with sloping or peaked ceilings install your smoke alarm 0.9 m from the highest
point measured horizontally, because "dead air" at the apex may prevent smoke from reach-
ing the unit, see Figure 5.

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 1.5 m away from fluorescent light fittings as electrical "noise" and/or
