Smoke alarms save lives — but not all alarms are created equal. In Queensland, photoelectric smoke alarms have become the new standard under updated legislation, and for good reason.
In this post, we’ll explain why photoelectric smoke alarms are now the top choice, how they work, and what makes them superior to older technologies like ionisation alarms.
Photoelectric smoke alarms detect visible smoke particles using a light beam inside the alarm. When smoke enters the chamber, it scatters the light, triggering the alarm.
They’re especially effective at detecting smouldering fires—slow-burning fires that produce a lot of smoke before flames appear.
Here’s why they’ve become the preferred choice in Queensland:
These alarms respond faster to smoke-heavy fires, giving families more time to escape.
They’re less likely to be triggered by cooking smoke or steam from showers compared to ionisation alarms.
Fire departments across Australia and the world now recommend photoelectric alarms as the safest option.
Under current and upcoming smoke alarm laws, all Queensland homes must install photoelectric smoke alarms that are:
Interconnected (when one sounds, they all sound)
Located in every bedroom, hallway, and on every level of the home
Compliant with Australian Standard AS 3786-2014
If you’re renting or selling a property, these rules already apply. For homeowners, the deadline is 2027.
One of the biggest advantages of photoelectric alarms is early warning. In a smouldering fire (like from a phone charging on a bed), ionisation alarms may take minutes longer to respond — and every second counts.
Photoelectric alarms can buy you and your family crucial extra minutes to escape safely.
Modern photoelectric alarms are designed for convenience:
Many come with 10-year lithium batteries
No hardwiring needed for some models
Easy to test and clean
And with professional help, you can make sure everything is installed correctly and meets legal standards.
