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 a 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.
From first of January 2027
All private homes, townhouses and units will require 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.
The legislation requires smoke alarms must be installed in the following locations:
on each storey
in each bedroom
in hallways that connect bedrooms and the rest of the dwelling
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.
What’s required by law?
When it is time for your property's alarms to be upgraded, those alarms must:
be photoelectric and comply with Australian Standard 3786-2014
not also contain an ionisation sensor; and
be less than 10 years old; and
operate when tested; and
be interconnected with every other ‘required’ smoke alarm in the dwelling so all activate together.
Any existing smoke alarm being replaced from 1 January 2017 must be a photoelectric-type alarm which complies with Australian Standard 3786-2014.
If a smoke alarm which is hardwired to the domestic power supply needs replacement, it must be replaced with a hardwired photoelectric smoke alarm.
In existing domestic dwellings, it is possible to have a combination of smoke alarms (240v and battery operated) and interconnectivity can be both wired and wireless.
