From 1 January 2017

  • Existing smoke alarms manufactured more than 10 years ago must be replaced with photoelectric smoke alarms which comply with Australian Standards (AS) 3786-2014. (Note: the date should be stamped on the back)
  • Smoke alarms that do not operate when tested must be replaced immediately.
  • Existing hardwired smoke alarms that need replacement, must be replaced with a hardwired photoelectric smoke alarm.
  • It is also recommended that:
    • smoke alarms be either hardwired or
    • powered by a non-removable 10-year battery; and
    • ionisation smoke alarms be replaced with photoelectric type as soon as possible.
    • For the best protection smoke alarms should be installed on each storey:
        • in every bedroom
        • in hallways which connect bedrooms and the rest of the dwelling
        • if there is no hallway, between the bedrooms and other parts of the storey; and
    • If there are no bedrooms on a storey, at least one smoke alarm should be installed in the most likely path of travel to exit the dwelling.
    • All smoke alarms should be interconnected.
To get everyone out safely during a house fire, it is essential to also have a well-practised fire escape plan. Existing landlord’s and tenant’s obligations continue. Property sellers must continue to lodge a Form 24 stating the requirements of the legislation have been met. See New Smoke Alarm Legislation for more details.

From 1 January 2022

  • All homes or units being sold or leased, or existing leases renewed, will require the installation of hardwired photoelectric, interconnected smoke alarms. If a hardwired smoke alarm cannot be installed, non-removable 10-year battery smoke alarms can be installed in place.
  • Smoke alarms in the dwelling must:
    • be photoelectric (AS3786-2014); and
    • not also contain an ionisation sensor; and
    • Be hardwired to the mains power supply with a backup power source (i.e. battery), although dwellings which were existing prior to 1 Jan 2017 can be hardwired or powered by a non-removable 10-year battery, or a combination of both.
    • be interconnected with every other smoke alarm in the dwelling so all activate together.
  • The legislation requires smoke alarms must be installed in the following locations:

    • if there is no hallway, between the bedroom and other parts of the storey; and
    • if there are no bedrooms on a storey, at least one smoke alarm must be installed in the most likely path of travel to exit the dwelling.
  • If a smoke alarm which is hardwired to the domestic power supply needs replacement, it must be replaced with a hardwired photoelectric smoke alarm.
