Smoke alarm installation in Brisbane
From 1 January 2027 every remaining domestic dwelling in Queensland needs photoelectric smoke alarms interconnected so that one sounding sets off all of them. Rental properties have had to meet that standard since 1 January 2022. Most homes still have single alarms that were never connected to each other.

Getting the detail right matters, because a compliant alarm in the wrong position is still not doing its job.
Hoff installs photoelectric alarms, interconnects them so that one alarm triggers all of them, and sets out positions based on the actual layout of the home.

Why people call
Common reasons for this job.
- Existing alarms are past their expiry date

- An alarm chirps, false-alarms or will not silence
- There is no alarm in or near a bedroom
How Hoff works
The approach.
Placement is worked out from the plan of the house, not by putting one alarm in the hallway and calling it done. Bedrooms, the paths between bedrooms and the exit, and each storey all factor in.
Interconnection is the part people most often lack. An alarm at the far end of the house going off on its own may not wake someone in a bedroom with the door shut, which is the entire reason interconnection exists.
Every alarm is tested before Hoff leaves and you are shown how to test and maintain them yourself.
Queensland requires photoelectric smoke alarms meeting AS 3786-2014, interconnected so that one alarm sounds them all, positioned in every bedroom, in the hallways connecting bedrooms to exits, and on every level of the dwelling. Rental properties have had to meet this since 1 January 2022. From 1 January 2027 the same requirement applies to all remaining domestic dwellings, including owner-occupied homes. Confirmed with the Queensland Fire Department and the Residential Tenancies Authority in August 2026. Your obligation depends on your specific dwelling, so check it with them rather than relying on this summary.

Smoke alarms questions.
From that date every remaining domestic dwelling in Queensland, including owner-occupied homes, needs photoelectric smoke alarms interconnected so they all sound together. Rental properties have had to meet the same requirement since 1 January 2022. Most homes still have single, unconnected alarms, and it is a straightforward job to bring them up to standard. Confirm your own obligation with the Queensland Fire Department.
Photoelectric alarms meeting AS 3786-2014, not containing an ionisation sensor, less than 10 years old, working when tested, and interconnected with every other alarm in the dwelling. Placement covers bedrooms, the hallways between bedrooms and exits, and every level.
When one alarm detects smoke, every alarm in the dwelling sounds. It matters most at night, when a single alarm at the other end of the house may not wake someone behind a closed bedroom door.
Alarms have a service life marked on the unit and should be replaced by that date. If you cannot find a date on yours, Hoff can check it while he is there.
A regular short chirp is usually a low backup battery or an alarm reaching end of life. If replacing the battery does not resolve it, the unit itself is likely due.
Yes. It is common to add or replace alarms during a lighting job or a switchboard upgrade, which saves a separate visit.
