sec.11 Installation of smoke alarm
A smoke alarm must be installed in each bedroom of the domestic dwelling in a place that complies with section 12 . Each smoke alarm— must comply with AS 3786–2014; and must contain a photoelectric sensor and not an ionisation sensor; and must be hardwired to the domestic dwelling’s electricity supply; and must be interconnected to every other smoke alarm installed in the dwelling. For subsection (2) (d) , a smoke alarm (the first smoke alarm ) is interconnected to another smoke alarm if— the first smoke alarm sounds an alert if the other smoke alarm is activated because its sensor detects smoke; and the other smoke alarm sounds an alert if the first smoke alarm is activated because its sensor detects smoke. However, subsections (1) and (2) do not apply to a sole-occupancy unit in a class 2 building if a smoke detection system that complies with the BCA, specification E2.2a, clause 4, has been installed in the sole-occupancy unit. If the BCA is inconsistent with this section, this section prevails to the extent of the inconsistency.
