Smoke Alarms Residential

QLD Smoke Alarm Legislation has changed. 


From 1 January 2022, you will need interconnected smoke alarms. This means, when one goes off they all go off.

Landlords, must install interconnected photoelectric smoke alarms (AS 3786-2014) in residential rental properties as of 1 January 2022.

The new laws also apply to residential properties that have done substantial renovations, new properties and properties for sale must be fitted with interconnected, photoelectric smoke alarm systems. 

How can we help?


Jarcel Electricals' licensed electricians are able to assist with smoke detector installations, interconnected upgrades, testing & maintenance.

Smoke alarms that are hardwired to the domestic power supply (240v), must be replaced with another hardwired photoelectric smoke alarm. Any 204v smoke alarm replacements must be done by a licensed electrician. 

You can have a combination of smoke alarms (240v and battery operated) and interconnectivity can be both wired and/or wireless.

We are experts in the requirements for smoke alarms and can offer affordable suggestions if we find your current setup is not compliant.

What is an interconnected smoke alarm?

This simply means that when one goes off they all go off in every room. The connecting of smoke alarms can be done wirelessly (e.g. via RF module) or hardwired. Regular electrical testing of the individual units, as well as the entire system is recommended.

What are the benefits of a photoelectric smoke alarm?

A photoelectric, interconnected smoke alarm is the most effective in detecting fire warning signs early as they have a quicker response time when detecting fires.

Their advanced technology is able to detect particles of smoke or ash in the air, meaning that the alarm will sound earlier than a regular smoke alarm. Regular smoke alarms require a certain amount of smoke to be present before sounding, which happens later than ash particles entering the air.

When every moment counts in the case of a fire and subsequent evacuation, your choice of smoke alarm, and regular maintenance of that alarm, matters.
