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.
If they are replaced they must be replaced with AS3786-2014 compliant photoelectric smoke alarms and powered by what is currently there (i.e. if they are powered by 240-volt they must be replaced with 240-volt smoke detectors, otherwise they can be powered by 10 year non-removable batteries)
From 1 Jan 2027, all smoke alarms are required to be interconnected and 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.
