All new homes or units and substantially renovated homes or units that are subject to a building application submitted from 1 January 2017, will require the installation of hardwired, photoelectric interconnected smoke alarms.
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 secondary power source (i.e. battery); and
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:
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.
Smoke alarms must be hardwired, or for existing dwellings, they can also be powered by a non-removable 10-year battery.
To get everyone out safely during a house fire, it is essential to also have a well-practised fire escape plan.
