BUILDING REGULATION 2021 - REG 11

11 Installation of smoke alarm

(1) A smoke alarm must be installed in each bedroom of the domestic dwelling in a place that complies with section 12 .

(2) Each smoke alarm—

(a) must comply with AS 3786–2014; and

(b) must contain a photoelectric sensor and not an ionisation sensor; and

(c) must be hardwired to the domestic dwelling’s electricity supply; and

(d) must be interconnected to every other smoke alarm installed in the dwelling.

(3) For subsection (2) (d) , a smoke alarm (the
"first smoke alarm" ) is interconnected to another smoke alarm if—

(a) the first smoke alarm sounds an alert if the other smoke alarm is activated because its sensor detects smoke; and

(b) the other smoke alarm sounds an alert if the first smoke alarm is activated because its sensor detects smoke.

(4) 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.

(5) If the BCA is inconsistent with this section, this section prevails to the extent of the inconsistency.
