Smoke detectors are one of the most important safety devices you can have in your building. They detect airborne smoke, and then provide an early warning alarm and enable emergency action in the event of a fire.
Smoke detectors are inexpensive, easy to install, inconspicuous, and require little maintenance.
Since 1 July 1997, the installation of smoke detectors became mandatory for all new residential buildings in WA. No building should be without them.
