Smoke alarms must be
installed:
-
(on a storey containing
bedrooms), located between each part of the dwelling containing bedrooms and
the remainder of the dwelling, and the hallway to the bedrooms; and
-
in any other storey not
containing bedrooms.[1]

A system of lighting must be
installed consisting of a light incorporated within the smoke alarm, or
lighting in the hallway or corridor or area served by the smoke alarm.[2]

Smoke alarms must be
installed:
-
(on every storey containing
bedrooms) between each part of the unit containing bedrooms and the remainder
of the unit, and any hallway servicing bedrooms;
-
in storeys with no bedroom
alarms must be installed in egress paths
Where the building itself has no sprinkler system
alarms complying with AS 1670.1, alarms must be installed in public corridors
and other internal public spaces, and connected to an occupant warning
system.[3]

In
areas where the use of the areas is likely to result in spurious signals
(e.g. a kitchen), any other alarm deemed suitable in accordance with AS
1670.1 may be installed as long as alarms are installed elsewhere in the
sole occupancy unit. An alarm acknowledgement facility may alternatively be
used in these areas. If the area in question has sprinklers the alarms need
not be installed in that area.[4]
