IMPORTANT SAFETY INFORMATION 
Please read and save these instructions
•
  This heat alarm requires constant 240V~ power and a  
  healthy 9V d.c. battery to operate properly. This heat  
  alarm will not work if a.c. supply is not connected, or  
  has failed or been interrupted for any reason, and the  
  batteries have been removed or are fl at or improperly  
  connected. Do not use any other kind of battery except  
  as specifi ed in this manual. Do not interconnect this  
  heat alarm to any other type of smoke alarm or 
  heat alarm or auxiliary device, except those listed in 
 this manual.
• 
The Push-to-Test button accurately tests all heat 
  alarm functions. Do not use any other test method for  
  routine testing. Test heat alarm weekly to ensure 
 proper operation.
•
  Higher ceilings will increase the time needed by the 
  heat alarm to detect a fi re. In most dwellings the 
  ceiling height will keep this reaction time within  
  acceptable limits. However, ceilings with a height of 
  over 6 metres may delay the reaction time of the heat  
 alarm signifi cantly.
•
  Advice from your local distributor or Fire Brigade should  
  be obtained when installing a heat alarm on a ceiling  
  higher than 6m.
•
  Only a qualifi ed electrician or similarly qualifi ed 
  person should install this heat alarm. The installation 
  should comply with all prevailing local, regional and  
 national codes.
•
  This heat alarm is designed to be used only as part of  
  the protection of a single-family dwelling or a house in  
  multiple occupation of no more than two storeys. It may  
  also be used in conjunction with smoke alarms within  
  individual fl ats or apartments in larger houses in 
3
  multiple occupation, to provide an early warning to  
  occupants of a fi re in a room within the dwelling but a  
  communal fi re alarm system should also be provided 
  in such cases. 
•
  Heat alarms should only be used in conjunction with  
  smoke alarms, with which the heat alarms should be  
  interconnected, in order to provide early warning of  
  heat, smoke, or fi re. Smoke alarms should be installed  
  on every level of the dwelling.
•
  Interconnected heat alarms and smoke alarms offer  
  maximum protection. By interconnecting heat alarms  
  and smoke alarms, when one unit senses heat, smoke,  
  or fi re, and sounds its alarm, all others will sound as  
  well. Do not connect this heat alarm to any other type  
  of alarm (except those stated in this manual) or  
  approved auxiliary device.
•
 Heat alarms interconnected with smoke alarms may  
  not alert every household member in time. The alarm  
  sounder of the heat alarm is loud in order to alert  
  individuals of a potential danger. However, there may 
  be limiting circumstances where an occupant may not  
  hear the alarm (eg. outdoor or indoor noise, sounder  
  sleepers, drug or alcohol usage, impaired hearing, etc.)  
  Household members must hear the alarm’s warning  
  sound and quickly respond to it to reduce the risk of  
  damage, injury, or death that may result from fi re. 
•
 Check carefully that, when any one device operates, 
the alarm signal given by interconnected devices is 
clearly audible throughout the building, particularly in  
bedrooms, where it is essential that the alarm signal 
will wake sleeping occupants.
•
  This heat alarm can only sound an alarm when 
it detects temperatures of 73°C to comply within  
the range of 58°C to 88°C per AS1603.3-1996.  
Heat alarms do not sense smoke or gas. In some fi res, 
hazardous levels of toxic chemicals and smoke can 
build up before a heat alarm will operate. Temperatures  
may not reach the alarm point to activate the heat  
alarm quickly enough to ensure safe escape.
•
  Some fi res are slow smouldering, low heat-producing,  
  or are in a different room to that in which the heat  
  alarm is located, or the heat from the fi re may bypass  
  the alarm, the heat alarm may not give a warning under 
 these circumstances.
•
  Heat alarms have limitations. This heat alarm is not  
  guaranteed to protect lives or property. Heat alarms are  
  not a substitute for insurance. Householders should  
  insure their lives and property in addition, as with any  
  electronic device, it is possible for the heat alarm to fail  
  at any time.
•
  Never paint this heat alarm.

HEAT ALARM LOCATION
Heat alarms are ideal for kitchens, garages, cellars, boiler 
rooms, attics and other areas where there are normally high 
levels of fumes, smoke or dust which preclude the use of 
smoke alarms due to the risk of false alarms. For normalsized houses, two-story houses, fl ats and maisonettes, it is 
recommended that the minimum level of protection should 
comprise smoke alarms in the hallways and staircases. 
This minimum standard necessitates one smoke alarm in 
the hallway of a typical bungalow or one smoke alarm on 
each level of a two-story house. Heat alarms should not be 
used in these circulation areas. If there are, for example, 
long hallways, the standard necessitates additional 
interconnected smoke alarms. 
If, however, the design of the dwelling does not comply 
with modern fi re safety standards, or if factors such as the 
presence of several young children, of elderly occupants or 
disabled people, or of smokers, the use of portable heaters 
or solid fuel fi res during the night, or the use of electric 
blankets, it is advised that additional detection devices, 
installed within rooms, may be necessary.

For best protection, it is recommended that you install 
a smoke or heat alarm in every room. In addition, it is 
recommended that all smoke and heat alarms should 
be interconnected. 
Note: Smoke alarms should be installed per AS1670.6 
Standard. 
Install heat alarm as close to the centre of the ceiling 
as possible. If the centre is not practical, mount the heat 
alarm no closer than 300mm away from a wall or corner. 
In rooms with open joists or beams, all ceiling-mounted 
alarms should be located on the bottom of such joists or 
beams and not up in joist channels. On sloped, peaked or 
5
gabled ceilings, install Heat alarm 300mm from highest 
point. If only wall placement is possible, install no further 
than 300mm from ceiling.
DO NOT INSTALL HEAT ALARMS
•
  Directly over the cooker, stove or oven.
•
  In areas with high humidity, like bathrooms or shower  
  rooms, or areas near dishwashers or washing  
  machines. Install heat alarms at least 3m away from  
  these areas if possible.
•
  Adjacent to, or directly above, heaters, air-conditioning  
  vents or ceiling fans.
•
  In an area where the temperature may fall below +5°C  
  or rise above +45°C. 
• 
Near fl uorescent lights. Electrical “noise” and fl ickering 
  may affect the operation of the heat alarm. 
•
  Closer than 300mm to light fi ttings.
•
  In such a position that it is diffi cult or dangerous to  
  reach for testing, maintenance or battery replacement.
HOW TO INSTALL THIS HEAT ALARM 
DANGER: electric shock hazards. Turn off power to the 
heat alarm circuit at the main distribution board by removing 
the fuse or switching the circuit breaker to the off position 
and securing it.
WARNING, only a qualifi ed electrician in accordance with 
AS/NZS3000 guidelines should install this heat alarm.
Heat alarms should be connected on a single independent, 
dedicated circuit at the main distribution board. No 
other electrical equipment, except compatible smoke 
alarms, should be connected to this circuit. If your home 
has residual current device protection on the electrical 
installation or on individual circuits, check with a qualifi ed 
electrician to make sure that faults on circuits serving 
socket outlets or portable appliances cannot cause 
interruption to the supply to the heat alarms. 
Heat alarms may also be connected to a separate 
electrically protected, regularly used local lighting circuit. 
However, this will mean that, unless a separate means of 
isolation is provided for the heat alarms, it will be necessary 
to isolate the lighting circuit every time that there is a need 
to isolate the supply to the heat alarms; this may cause 
inconvenience or hazards.
