By law at least one smoke alarm must be installed on each level
of your home (Figure 1B).
Recommended Locations
•
In every room where someone sleeps with the door closed. The
closed door may prevent an alarm located outside from waking the
sleeper.
•
In the immediate area of bedrooms and the exit path from all
sleeping areas (Figure 1A).
•
In stairways, as stairways act like chimneys for smoke and heat.
•
In any room where large electrical appliances are operated (e.g.,
portable heaters or humidifiers).
•
If a hallway or room is more than 9.1m long put alarms at both ends.
•
For maximum household protection see Figure 1C.
Things to Consider:
For Ceiling Mounting:
•
Smoke from a fire will rise to the ceiling and spread horizontally.
Mounting the smoke alarm in the centre of the ceiling places it
closest to all points in the room.
•
When mounting an alarm on the ceiling, locate it at a minimum of
30cm from the side wall (Figure 2A).
•
For sloped, peaked or cathedral ceilings the alarm should be placed
between 500mm and 1500mm from the highest point of the ceiling
(Figure 2B).
•
Smoke alarms in rooms with ceiling slopes greater than 1m in 8m
horizontally, should be located on the high side of the room (Figure
2B).
For Wall Mounting:
•
When mounting the alarm on the wall, use an interior wall with the
top edge of the alarm at a minimum of 10cm and a maximum of
30cm below the ceiling (Figure 2A).
