Smoke Alarms

From 1 May 2006, legislation requires the installation of smoke alarms in buildings in which people sleep.Smoke Alarm

  • Property owners are responsible for ensuring smoke alarms are installed.
  • Smoke alarms suitable for installation in homes are either hard-wired to mains power or battery powered.
  • All smoke alarms need to be checked on a regular basis. If you have installed or are about to install battery powered smoke alarms, we suggest you check, at least twice a year, say at the start and end of daylight saving time, that the batteries and thus the smoke alarms are working. 
  • It is also recommended that a suitable number of alarms be installed and that the alarms can be heard throughout a large house.

The NSW Government Department of Planning has developed guidelines setting out the type of smoke alarms to be installed in each type of building. Detailed information regarding the smoke alarm requirements and the legislation can be found on their website at

Information on smoke alarms can also be found on the NSW Fire Brigades website at
