Recommended Location o Alarms
• Emerging smoke rises to the ceiling and spreads horizontally. Mounting the alarm on
the ceiling close to the centre of the room provides the best protection. Ceiling
mounting, rather than wall mounting, is preferred in normal residential construction.
• When mounting alarms on the ceiling locate it at least 300mm away from the side
wall and 300mm away from any corner. (see diagram overleaf).
• When mounting alarms on a wall, use the inside wall. The recommended position is
between 300mm and 500mm o the ceiling. (see diagram overleaf).
• When mounting the alarm at the apex of a sloping ceiling it should be located at
least 500mm away from the apex but should not exceed 1500mm (see diagram
overleaf).
• Locate at least one alarm on every oor level.
• Locate an alarm in every room where electrical appliances are operated (i.e. Portable
heaters or humidiers).
• Locate an alarm for each separate sleeping area in the immediate vicinity of the
bedrooms. Monitor the exit path as the bedrooms are usually farthest from an exit.
• Locate smoke alarm at both ends of a bedroom hallway or large room if the hallway
or room is more than 9m long.
Note: The performance of smoke alarms mounted on walls is unpredictable and this
mounting position is not recommended when ceiling mounting can be implemented.

Recommended Location o Alarms
• Locate additional alarms to monitor any stairway as stairways act like chimneys for
smoke and heat.
• For mobile home installation select location carefully to avoid thermal barrier that
may form at the ceiling. For more details see Mobile Home Installation.
• Do not locate smoke alarms in kitchen areas due to potential nuisance alarms from
cooking fumes.
• Incorrect orientation of smoke alarm may decrease operation eectiveness.

Mobile Home Installation
• Modern mobile homes have been designed and insulated to be energy ecient.
Install smoke alarms as recommended (refer to Recommended Locations).
• In older mobile homes that are not well insulated compared to present standards,
extreme heat or cold can be transferred from the outside through poorly insulated
walls and the roof. This may create a thermal barrier which can prevent smoke from
reaching a smoke alarm mounted on the ceiling. In such units, install smoke alarm on
inside partition between 300mm and 500mm from the ceiling.
• If you are not sure about the insulation in your mobile home, or if you notice the
walls and ceilings are either hot or cold, install alarm on an inside wall. For minimum
protection, install one alarm close to the bedrooms.
Note: Test your smoke alarm operation after mobile home vehicle has been in storage,
before each trip and at least once a week during use.
Avoid these Locations
• Do not locate your alarm in the garage - vehicles and workshop equipment can cause
fumes.
• Do not locate your alarm in front of forced air supply ducts used for heating and air
conditioning and other high air ow areas.
• Do not locate your alarm less than 500mm from the peak of an "A" frame type ceiling.
•
Do not locate your alarm in areas where temperatures may fall below 5°C or rise above
40°C, or in humidity higher than 90% as these conditions may reduce battery life.

Avoid these Locations
• Avoid dusty areas, dust particles may cause smoke alarm to false alarm or fail to alarm.
• Avoid very humid areas or near a bathroom or laundry, moisture can cause false alarm.
• Avoid insect-infested areas.
• Do not locate alarm within 0.9m of the following: the door to a kitchen, the door to a
bathroom containing a tub or shower, a ceiling or whole house ventilating fan, or
other high ow areas.
• Avoid locating near uorescent lights or other electrical equipment. Electronic
magnetic interferences or“noise”may cause nuisance alarms or chirping.
• Smoke alarms are not to be used with detector guards unless the combination (alarm
and guard) has been evaluated and found suitable for that purpose.
False Alarms
• This smoke alarm is designed to minimize false alarms. Smoking will not normally set
o the alarm unless smoke is blown directly into the alarm.
• Combustion particles from cooking may set o the alarm if the alarm is located close
to the kitchen cooking surface or appliance.
• Large quantities of combustion particles are generated from spills and over-boil.
• An alarm with a Hush Control device is preferable near a kitchen environment for this
reason.
Alarm Cleaning
To prevent false alarming caused by buildup of dust and insects, remove base plate
from alarm (see pg 8) and carefully vacuum all gaps and openings with the brush
attachment on your household vacuum cleaner. Repeat procedure every 6 months.

False Alarms
• Photoelectric type smoke alarms are less prone to false alarm near kitchen areas than
ionisation type smoke alarms.
• If the alarm does sound, check for re rst. If a re is discovered, escape quickly and
call the Fire Brigade. If no re is present, check to see if one of the reasons listed on
previous page may have activated the alarm.
How To Remove Smoke Alarm rom Base Plate
• Switch o mains power.
• Remove Tamper Locking Screw (if installed).
• Look for‘PUSH to OPEN‘ (Fig.3).
• Push rmly towards arrow until smoke alarm unhinges from base plate.
(Fig.3)
Installation
• This Smoke Alarm can only interconnect with other alarms of the same model.
Interconnection with other brands may cause damage or result in a shock or re risk
and void warranty.

Installation
• These smoke alarms must be installed by a registered electrician.
• Due to“noise”from electromagnetic interference, no more than 24 of these smoke
alarms may be interconnected.
• There are three terminals in the supply terminal block, marked A, S, N. It is important
that the alarm be wired correctly to ensure correct operation. Incorrect wiring to the
Smoke Alarm will damage the unit and void the warranty.
• A total maximum of 250 meters (820 feet) of wire can be used in interconnecting
smoke alarms.
• All nal sub-circuit conductors including the signal conductor must be a minimum
size of 1mm with 250V grade insulation.
• Interconnected Smoke Alarms must be connected to the same nal subcircuit.
• Do not use any wire that could later be confused with the normal house wires for the
interconnect wire. For example, green/yellow earth wire.
• Do not connect AC power wires to S interconnect terminal. These will damage smoke
alarms.
• Do not connect the S interconnect wire to any device, except the S interconnect
terminal of the smoke alarm. Otherwise, the smoke alarm will be damaged.
• Smoke alarms should be interconnected only within the connes of a single family
living unit. If smoke alarms are interconnected between dierent units, there may be
excessive nuisance alarms. Residents may not be aware that smoke alarms are being
tested or that it is a nuisance alarm caused by cooking etc.
