Smoke alarms are essential for homes in NSW and only a trained electrician is qualified to install and check alarms in your home or workspace. Smoke alarms are mandated by law for good reason. Both smoke and flames can kill occupants so an early warning will make all the difference. Smoke alarms detect fires and are ready to alert occupants any time of the day or night.
Our professional electricians can ensure that your home or commercial premises are defended by smoke alarms. One smoke alarm should be installed on every floor of your home at a minimum, and FRNSW recommends additional installations outside sleeping areas and inside bedrooms.

Our electricians can also keep your smoke alarms in good working order and replace devices and batteries on a regular basis as required.

Yes, smoke alarms are legally required in all Australian homes, and the exact requirements depend on your state and when the property was built or renovated. In general, alarms must be installed on every level of the home and positioned to alert occupants early in the event of a fire.
Most regulations now require photoelectric smoke alarms that meet Australian Standard AS3786. In many cases, they must also be interconnected, meaning when one alarm is triggered, they all sound throughout the home.
Smoke alarms should be installed:
They should be placed on ceilings (or high on walls) and positioned to detect smoke early while avoiding areas like corners or drafts that can affect performance.
This depends on the age and type of your property. Newer homes and upgrades typically require hardwired (mains-powered) alarms with battery backup, while some existing homes may use 10-year sealed battery alarms. A professional can confirm what’s required for your property to stay compliant.
Smoke alarms should generally be replaced every 10 years, as their sensors degrade over time. They should also be tested regularly (monthly is recommended) to ensure they are working correctly and will activate in an emergency.
While some battery-powered alarms can be installed yourself, hardwired or interconnected systems must be installed by a licensed electrician to ensure they meet safety standards and legal requirements. Professional installation also ensures correct placement and full compliance.
