New smoke alarm laws now apply in Queensland

New and substantially renovated homes are now required to have interconnected Australian Standard (AS) 3786-2014 photoelectric smoke alarms in all bedrooms, in hallways where bedrooms are connected, and on each and every level of the residence. This applies to homes where building applications were lodged after 1 January 2017.

Requirements for other homes will be phased in over 10 years. Interconnected AS 3786-2014 photoelectric smoke alarms will be required from:

  • 1 January 2022 in all homes leased and sold
  • 1 January 2027 in all other homes.

To comply with the new laws homeowners can install either hardwired 240V smoke alarms or non-removable 10-year battery smoke alarms. However, any existing hardwired 240V smoke alarm must be replaced with a hardwired 240V photoelectric smoke alarm. The installation of hardwired 240V smoke alarms must be performed by a licenced electrician. In existing homes, it is possible to have a combination of smoke alarms, which can be 240V or battery operated and interconnectivity which can be both wired and wireless.

Safety checklist

Turn off electricity at the switchboard before you enter the ceiling space and start any work.
Isolate, lockout and tag.
Undertake risk assessment.
Confirm conductive foil insulation is not energised.
Confirm whether the ceiling sheeting contains asbestos. If it does and the alarm must be installed there, follow safe work procedures for asbestos.
Replace fluids regularly when working in hot conditions. Our heat stress page has information and safe work procedures.
Always let someone know before heading into the ceiling space and maintain contact with them.
Step carefully on joists and beams and not on the ceiling material. Our work at heights page has more information.
On completion of the electrical work ensure testing of circuits in accordance with Section 8 of the Wiring Rules.
Issue certificate of testing and safety.

There's nothing like getting back for getting better

Workers who get back to safe work as soon as possible recover more quickly than those who wait until they are fully recovered.
