3. Installation Instructions
This smoke alarm must only be wired to a 240VAC 50Hz sine wave
current supply.
Laws on smoke alarms vary from state to state and you should be
aware of what the requirements are in the state you live - for more
information please refer to your local fire emergency services.
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
300mm 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 100mm and a maximum of
600mm below the ceiling (Figure 2A).
