Smoke Alarm Testing & Installation

E.J Electrical & Communications offer smoke alarm testing, supply and installation to both commercial and domestic customers. We also offer an annual smoke alarm maintenance agreement for rental and commercial properties. As part of the smoke alarm testing service, we include safety switch testing free of charge. 

Queensland Smoke Alarm Legislation

As of 1st January 2017, new smoke alarm laws became effective. For new dwellings or where a substantial renovation is undertaken the new laws will apply immediately, meaning:


  • photoelectric (AS3786-2014) alarms only;

  • cannot also contain an ionisation sensor;

  • be hardwired to the mains power supply with a secondary power source (battery);

  • be interconnected with every other smoke alarm.

The legislation requires that smoke alarms be installed in the following locations:

  • on each storey

  • in each bedroom;

  • in hallways serving bedrooms and the rest of the dwelling; 

  • if there is no hallway, between the bedroom and other parts of the storey; and

  • installed in the exit path of every storey not containing bedrooms.

Smoke alarms must be hardwired, or for existing dwellings, they can also be powered by a non-removable 10-year battery.

For existing dwellings the new laws will come into effect as of 1st January 2027. For dwellings being sold, leased or an existing lease renewed, the new laws will come into effect as of 1st January 2022.


However, if the existing smoke alarms are manufactured more than 10 years ago or the alarms don’t work when tested, they will have to be replaced with photoelectric alarms which comply with Australian Standard (AS) 3786-2014.
