Warnings
• To prevent injury, this device must be securely attached to the
ceiling/wall in accordance with the installation instructions.
• Batteries should not be exposed to excessive heat such as sunshine,
fire or the like.
• Do not paint or cover the smoke alarm.
Where to install a smoke alarm
• As a minimum, smoke alarms should be located between sleeping
areas and potential sources of fire such as living rooms and kitchens.
In single story homes with one sleeping area, a smoke alarm should be
installed in the hallway, as close as possible to the living
accommodation. To ensure audibility in bedrooms, no smoke alarm
should be further away than 3m from any bedroom door. It may be
necessary to install more than one smoke alarm, particularly if the
hallway is more than 15m long. In single story homes with two
separate sleeping areas, a minimum of two smoke alarms is required,
one outside each sleeping area. In multilevel or split level homes, as a
minimum a smoke alarm should be installed on the ground floor
between the staircase and any rooms in which a fire might start and
on each story in circulation areas which form part of escape route
(normally hallways and landings).
• Additional alarms should be installed in bedrooms in anticipation of
fires originating there, caused by faulty wiring, lights, appliances,
smokers or other hazards.
• For best protection, smoke alarms should be installed in every room in
your home, apart from those listed in the next section. Heat alarms
should be used in kitchens, boiler rooms, laundry rooms, garages and
such like, where smoke alarms would be unsuitable.
• Install smoke alarms in circulation areas at a distance no greater than
7.5m from the farthest wall, no greater than 7.5m from a door to any
room in which a fire might start and no greater than 7.5m from the
next smoke alarm.
• As it is impossible to predict the source of a fire, the best location for
an alarm is usually the center of a room or hallway. If it is necessary to
place a smoke alarm on a wall, always locate the detection element of
the alarm 150mm to 300mm (6 to 12 inches) below the ceiling and the
bottom of the alarm above the level of doors and other openings.

• In rooms with simple sloped, peaked or gabled ceilings, install smoke
alarms on the ceiling 900mm (3 feet) from the highest point of the
ceiling. "Dead air" at the peak of a ceiling may prevent the smoke
from reaching the alarm in time to provide an early warning.
Where not to install a smoke alarm
• In an environment with a high risk of draught (e.g. close to air
conditioning, fans and ventilation outlets). The movement of air can
impair the penetration of fire smoke into the smoke alarm.
• Areas where fumes or cooking smoke occur, such as kitchens.
• Areas with high humidity such as bathrooms, or close to appliances
such as dish washers or washing machines.
• Areas where dust can accumulate such as the garage or attic.
Mounting
• Place the mounting plate on the desired installation location and mark
where the holes should be drilled.
• Drill two holes with a diameter of 5 millimetres.
• Push the plastic plugs into the holes.
• Insert the screws into the mounting plate, and tighten them firmly into
the plugs.
• Place the smoke alarm on the mounting bracket and secure it by
turning it clockwise.
