Why hardwired alarms need a licensed electrician
Plenty of homes in Brisbane already have hardwired smoke alarms, often older ionisation models fitted years ago. They don't meet the current rules, and they can't simply be swapped for battery alarms from the hardware store.
- Existing 240V alarms must be replaced with 240V alarms.
- 240V alarms must be connected by a licensed electrician.
- New alarms must be photoelectric (AS 3786-2014) and interconnected.
- Alarms over 10 years old or that fail a test must be replaced.

A licensed electrician, not a handyman

Hardwired smoke alarm questions
Can I replace a hardwired smoke alarm with a battery one in QLD?
No. The Queensland Fire Department says existing 240V hardwired alarms must be replaced with 240V photoelectric alarms when replacement is needed.
Do hardwired smoke alarms need an electrician in Queensland?
Yes. 240V smoke alarms must be connected by a licensed electrician. Battery alarms with a 10-year non-removable battery can be fitted without one.
Why is my hardwired smoke alarm beeping?
A chirp often means the backup battery is low or the alarm has reached the end of its life. Smoke alarms must be replaced if they're over 10 years old or fail a test, so a beeping older unit is usually a sign it's time to upgrade.
Do I get paperwork for hardwired alarms?
Yes. Hardwired alarms installed by a licensed electrician come with a Certificate of Testing and Compliance.
Can new hardwired alarms connect to my existing wiring?
In most homes the new 240V alarms connect where the old ones were, and extra alarms are added where the rules require them. Your electrician will check the existing wiring on the day.
