  • Not also contain an ionisation sensor; and
  • Be less than 10 years old; and
  • Be interconnected with every other ‘required’ smoke alarm in the dwelling so all active together.

Any existing smoke alarm being replaced from 1 January 2017 must be photoelectric-type alarms which complies with AS 3786-2014

If a smoke alarm which is hardwired to a domestic power supply needs replacement, it must be replaced with a hardwired photoelectric smoke alarm.

In existing domestic dwellings, it is possible for have a combination of smoke alarms (240v and battery operated) and inter connectivity can be both wired and /or wireless.

Qld Legislation required that smoke alarms must be installed in the following locations:

  • On each storey
  • In each bedroom
  • In the hallways that connect bedrooms and the rest of the dwelling
  • If there is not hallway. Between the bedroom and other parts of the storey; and
  • If there are not bedrooms on a storey, at least one smoke alarm must be installed in the most likely path of travel to exit the dwelling.

From 1 January 2022:

Landlords:  If you are not compliant, you will not be legally able to rent your property.

New dwellings and dwelling being renovated must have photoelectric smoke alarms installed.

Selling/Buying:  All homes or units sold must have hardwired, photoelectric, interconnected smoke alarms.

Photo electrical Smoke Alarms detect visible particles of combustion.  These types of alarms are generally more effective across a wide range of fires experienced in homes.  They response quicker to smouldering fires and the dense smoke given off of foam filled furnishing and overheated PVC wiring.


  • Good for smouldering fire and dense smoke
  • Not as prone to cooking nuisance alarms
  • Contain no radioactive material
