Smoke Alarms

Members are reminded that although the date has passed, DFES promotes April Fools' Day (1 April) as a yearly reminder to regularly change smoke alarm batteries with a high-quality, long-life battery.

General tips

For householders without smoke alarms or who are thinking of upgrading, DFES recommends that 240-volt mains-powered photo-electric smoke alarms be installed by a qualified electrician. Click here for information about other types of smoke alarms.

Ensure that installation of all smoke alarms is in line with the Building Code of Australia - most manufacturers’ installation instructions are aligned to this code. Alarms should be securely fitted, double-sided tape and/or velcro is not acceptable.

Smoke alarms should be located in all sleeping areas, all paths of travel between sleeping areas and exits to open air. Click here for more information about where to install smoke alarms.

If you have smoke alarms with a changeable battery, you need to refer to the manufacturer’s instructions. DFES recommends replaceable batteries are changed annually. 

If you have mains-powered smoke alarms, read the manufacturer's instructions to check if they require back-up batteries that need changing. Some mains-powered smoke alarms have non-changeable batteries which do not require attention during the life of the smoke alarm.

All smoke alarms have a maximum service life of ten years and need to be replaced. Mains-powered smoke alarms must be fitted by a licensed electrical contractor. DFES recommends mains-powered photoelectric smoke alarms.

All smoke alarms must be regularly tested (recommended monthly so occupants are aware of the emergency alert) – all smoke alarms have a test button.

Smoke alarms must be clear of obstructions and not painted and DFES recommends removing any dust from the grille area with a soft brush attached to a vacuum cleaner.
