approximately 10 minutes.
n If the smoke alarm is sounding it can be desensitised by pressing the
“HUSH/TEST” button on the smoke alarm cover.
n After pressing the “HUSH/TEST” button, the alarm will silence immediately
and red LED will flash every 15 seconds for approximately 10 minutes to
indicate the alarm is in the temporary desensitised condition.
n The smoke alarm will automatically reactivate after approximately 10
minutes and sound the alarm if particles of combustion are still present.
n The “HUSH” feature may be used repeatedly until the air has cleared.
TESTING
NOTE: Before testing, make sure that the smoke alarm is connected to AC
power supply (make sure the green LED is ON) and there is a 9V battery
properly installed.
n Test alarm by pushing and holding the test “HUSH/TEST” button for 5
seconds. This should sound the alarm if all electronic circuitry and horn are
working.
n If no alarm sounds, check battery wiring, fuses or circuit breaker and make
certain that alarm is connected to a continuous final sub-circuit.
n With interconnected units, holding test button down on one unit will cause
all connected units to sound.
n Continuous chirping or erratic noise or low sound from an alarm may
indicate a defective alarm.
Smoke alarm should be tested on a monthly basis. To accurately test the
integrity of the sensing chamber use a smoke detector (aerosol) tester.
NOTE: After the above alarm test with the ‘HUSH/TEST’ button, the alarm will
be desensitised for about 10 minutes. ONLY DO THE SMOKE AEROSOL TEST
AFTER THIS DESENSITISED PERIOD.
WARNING: Do not apply excessive force on the “HUSH/TEST” button this may
damage the smoke alarm and may void the warranty.
WARNING: Never use an open flame of any kind to test your alarm. You may
damage the alarm or set fire to your home. The built-in test switch enables
testing of all electronic components and the horn.

Operation, Testing and Maintenance:
OPERATION
The smoke alarm is operational once all wires are properly connected, the
smoke alarm is correctly installed on the mounting base, battery inserted and
the alarm has been tested. There are two LED indicators. Each of them has a
unique function:
Red LED
n Stand-by condition: will flash once approximately every 60 seconds to
indicate unit is functioning properly.
n Alarm condition: will flash quickly when unit goes into alarm. The flashing
red LED and pulsating alarm will continue until the air is cleared. For
interconnected units, the originating smoke alarm red LED will be flashing.
All other units will sound but not flash.

Repairs and Services:
n If the smoke alarm is defective in any way, do not tamper with the unit.
See warranty for instructions on in-warranty returns. Note: NO USER
REPLACEABLE PARTS INSIDE.
643084 only:
n The smoke alarm uses a very small amount of radioactive element that
is safely contained within the sealed source.
NOTE: When this product is no longer required dispose by returning
to HPM Legrand office in your state capital or your state’s Health
Department. Alternative disposal is not permitted unless accepted
under your state’s Health and Safety Regulations.
n Please note: It is illegal to send radioactive material through Australia
Post. Check for similar conditions with any forwarding agency before
sending this article.
WARNING: DO NOT TAMPER WITH RADIOACTIVE SOURCE.
Mobile Home Installation:
n Modern mobile homes have been designed and insulated to be energy
efficient. Install smoke alarms as recommended (refer to RECOMMENDED
LOCATIONS).
n In mobile homes that are not well insulated extreme heat or cold can
be transferred from the outside through poorly insulated walls and roof.
This may create a thermal barrier that can prevent smoke from reaching
a smoke alarm mounted on the ceiling. In such units, install the smoke
alarm on inside partition between 300mm and 600mm from the ceiling.
n 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.
For additional protection, see SINGLE FLOOR plan. We recommend that the
smoke alarm be tested after each journey.
Installation of Smoke Alarms:
IMPORTANT: INCORRECT ORIENTATION OF SMOKE ALARMS MAY
DECREASE OPERATIONAL EFFECTIVENESS
Recommended Locations of Alarms:
n Install at least one alarm for each separate sleeping area. Try to cover the
exit path as the bedrooms are usually farthest from an exit. If there is more
than one sleeping area, install additional alarms in each sleeping area in the
immediate vicinity of bedrooms.
n Install at least one alarm to protect any stairway as stairways act like
chimneys for smoke and heat.
n Install at least one alarm on every floor level.
n Install an alarm in every room where a smoker sleeps as additional
protection.
n Install an alarm in every room where electrical appliances are operated (i.e.
portable heaters or humidifiers) as additional protection.
n Install an alarm in every room where someone sleeps with the door closed
as additional protection. The closed door may prevent the alarm from
waking the sleeper.
n Smoke, heat and other combustion products rise to the ceiling and spread
horizontally. Mounting the alarm on the ceiling in the centre of the room
places it closest to all points in the room. Ceiling mounting is preferred in
ordinary residential construction.
n For mobile home installation select location carefully to avoid thermal
barrier that may form at the ceiling. For more details see Mobile Home
Installation.
n When mounting an alarm on the ceiling install it at a minimum of 300mm
from the side wall and 600mm from any corner (see diagram).
n When mounting an alarm on a wall, install it at a minimum of 300mm from
the ceiling level but not more than 600mm from the ceiling level and any
corner (see diagram) NOTE: The performance of smoke alarms mounted on
a wall is unpredictable, and is not recommended when ceiling mounting can
be implemented.
n When mounting an alarm at the apex of a sloping ceiling it should be located
a minimum of 500mm from the apex but should not exceed 1500mm (see
diagram).
n Locate smoke alarm at both ends of a bedroom hallway if the hallway is
more than 9m long.
Avoid These Locations:
Do not place alarm in the following locations:
n The garage. Gas released when you start your automobile may cause false
alarms.
n In front of forced air supply ducts used for heating and air-conditioning and
other high airflow areas.
n In the peak of an “A” frame type of ceiling.
n In areas where temperatures may fall below +5ºC or rise above +50ºC.
n In dusty areas, dust particles may cause smoke alarm to false alarm or fail
to alarm.
n We do not recommend installation in or directly adjacent to areas of high
condensation such as bathrooms & laundries due to potential for false alarms.
n Kitchen/cooking areas.

Good Safety Habits:
The use of this product should not be seen as a substitute for basic safety
precaution in the prevention of fire.
n Do not smoke in bed.
n Do not leave children at home alone.
n Do not clean with flammable liquids, such as petrol.
n Safely store flammable materials.
n Smoke alarms must be tested regularly to ensure that the batteries and
alarm circuit are in good operating condition.

The Limitations of Smoke Alarms:
n Smoke alarms cannot provide an alarm if smoke does not reach the alarm.
Therefore, smoke alarms may not sense fires starting in chimneys, walls,
on roofs, on the other side of a closed door, or on a different floor.
n If the alarm is located outside the bedrooms, or on a different floor, it may
not wake up sound sleepers. A smoke alarm in the bedroom, is therefore
recommended as additional protection.
n Smoke alarms have been significant in saving lives in many parts of the
world. However, U.S. Government research indicates that they may not
give early enough warning in up to 35% of fires. Hence, the use of this
product does not act as a substitute for basic prevention.
n Although smoke alarms can help save lives by providing early warnings of
a fire, they are not a substitute for an insurance policy.
n This smoke alarm alone will not alert the hearing impaired. Use special
purpose smoke alarm with lights or vibrating devices, for those hard of
hearing.
Develop and Practise a Plan of Escape:
n Make a floor plan indicating all doors and windows and at least two
escape routes from each room. Second storey house windows may need
a rope or chain ladder.
n Have a family meeting and discuss your escape plan, showing everyone
what to do in case of fire.
n Determine a place outside your home where all of you can meet, if a fire
occurs.
n Familiarise everyone with the sound of the smoke alarm and practice
leaving your home when they hear it.
n Practice a fire drill at least every six months, including drills at night.
Practice allows you to test your plan before an emergency. You may not
be able to reach your children. It is important that they know what to do!
What to do when the Alarm Sounds:
n Leave immediately by your plan of escape. Every second counts, so don’t
waste time getting dressed or picking up valuables.
n In leaving, don’t open any inside door without first feeling its surface.
If hot, or if you see smoke seeping through cracks, don’t open that
door! Instead, use your alternative exit. If inside door is cool, place your
shoulder against it, open it slightly and be ready to slam it shut if heat and
smoke rush in.
n Stay close to the floor if air is smoky. Breathe shallowly through a wet
cloth if possible.
n Once outside, go to your selected meeting place and make sure everyone
is there.
n Call the Fire Brigade from your neighbour’s home - not from yours!
n Don’t return to your home until officials say that it is safe to do so. For
additional information on fire safety, contact your local Fire Brigade.
This smoke alarm has a maximum 10 year life span. THIS SMOKE ALARM HAS BEEN TESTED AND PASSED TO AS3786-1993

False Alarms:
n In very humid areas or near a bathroom, moisture can cause false alarms
in Ionisation smoke alarms.
n This smoke alarm is designed to minimise false alarms. Smoking will not
normally set off the alarm unless smoke is blown directly into the alarm.
n Combustion particles from cooking may set off the alarm if the alarm is
located close to the cooking surface.
n Because large quantities of combustion particles are generated from
spills or grilling an alarm with a Hush Control device is preferable near a
kitchen environment.
n If the alarm does sound, check for a fire before silencing the alarm. If a fire
is discovered, escape quickly and call the Fire Brigade.
