Installation
2
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).
