Rentals and properties being sold

Smoke alarms in the dwelling must:

i) be photoelectric (AS 3786-2014); and

ii) not also contain an ionisation sensor; and

iii) be less than 10 years old; and

iv) operate when tested; and

v) be interconnected with every other smoke alarm in the dwelling so all activate together.

Smoke alarms must be installed on each storey:

ii) in hallways which connect bedrooms and the rest of the dwelling; or

iii) if there is no hallway, between the bedrooms and other parts of the storey; and

iv) 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 powered by a non-removable 10-year battery, or a combination of both may be allowed.

There are special requirements for stairways, sloping ceilings, and ceilings with exposed beams. These requirements are explained in the Building Fire Safety Regulation 2008.
