Fire Safety

The following information is important for all property owners, property managers, tenants and business operators who own, occupy or manage buildings or various types of residential properties; from commercial, retail to industrial premises.


All residential dwellings, townhouses, units, apartments, flats, places of shared accommodation, moveable dwellings, holiday vans or park van annexes must have smoke alarms installed in appropriate locations under Division 7A of the Environmental Planning and Assessment Regulation.

All smoke alarms must comply with Australian Standard AS3786-1993 and can either be a:

  • Battery operated smoke alarm (ionisation or photoelectric types), with a hush button
  • Hardwired 240 Volts smoke alarm with battery backup (ionisation or photoelectric types). A licensed electrician must install        hardwired smoke alarms, which can also be interlinked together, so that they sound together.

Please note: Dwellings, alterations, and additions built since 1993 must have hardwired smoke alarms to comply with the Building Code of Australia.

The number of smoke alarms required will depend on the size and layout of each particular dwelling whilst the location will depend on the different class types of the dwellings. Details on the installation position requirements for your dwelling can be found at NSW Planning and Environment.

Care should always be taken to ensure that smoke alarms are not installed in areas of dead-air.

Please note: A penalty infringement notice is applicable if no smoke alarm is installed within the premises or moveable dwelling. It is also an offence to interfere with or remove a smoke alarm unless it is for the purpose of maintenance or replacement of the smoke alarm.


Conventional smoke alarms are not effective in alerting those with hearing impairments.A visual warning device which is interconnected to the smoke/heat alarm can be obtained. Also, a special emergency call service is available for people with a hearing impairment (or speech impairment) with direct access to fire safety emergency response.
