Not sure whether your Brisbane home meets Queensland’s smoke alarm requirements? You are not alone. Most homeowners assume their alarms are fine because they beep when tested — but a chirping alarm is often the first warning sign. But under QLD law, a working alarm is not the same as a compliant alarm.
This smoke alarm compliance checklist for QLD walks through every requirement your smoke alarms must meet. Grab a chair, a torch, and check each point against what is actually installed in your home. It takes about ten minutes and could save you thousands in fines — or something far worse.
The 7-point smoke alarm compliance checklist for QLD
Go through each of these checks. If you fail any single one, your home is not compliant under current Queensland legislation.
Are your alarms photoelectric?
Check the label on the back or side of each alarm. It should clearly state “photoelectric” or show the photoelectric symbol. If it says “ionisation” or “dual sensor” (with ionisation component), it does not meet the QLD standard.
Is there an alarm in every bedroom?
Walk through your home and check every room that is used for sleeping. This includes the master bedroom, kids’ rooms, spare rooms, sleepouts and any converted spaces used as bedrooms. Each one needs its own alarm on the ceiling.
Is there an alarm in the hallway connecting bedrooms?
The hallway or corridor that connects bedrooms to the rest of the dwelling needs an alarm. If your home has bedrooms on different sides or levels, each connecting pathway needs coverage.
Is there an alarm on every level of the home?
This includes upper floors, ground floors, and lower levels — even if a level has no bedrooms on it. A two-storey Brisbane home needs alarms on both storeys regardless of where people sleep.
Are all your alarms interconnected?
When one alarm detects smoke, every alarm in the home must sound at the same time. This can be achieved through hardwired interconnection or wireless RF interconnection. To test: trigger one alarm and listen for all others to activate simultaneously.
If each alarm operates independently, they are not interconnected — even if they are the right type.
What powers your alarms?
Check whether your alarms are hardwired (connected to 240V mains power with battery backup) or have a sealed, non-removable 10-year lithium battery. If you can open a compartment and swap the battery yourself, it is a removable 9V battery — and that is no longer compliant.
Do your alarms meet AS 3786:2014?
Look for the Australian Standard marking on each alarm. It should reference AS 3786:2014 (or later). Alarms manufactured to earlier standards — even if they are photoelectric — may not meet the current legislative requirement.
Score yourself
How did your home go?
If you scored anything less than 7 out of 7, your home is not yet compliant under Queensland’s smoke alarm legislation. Every single point must be met — there is no partial credit.
The most common issues we see in Brisbane homes
After assessing hundreds of Brisbane properties, these are the problems we see most often:
Ionisation alarms still installed
This is the single most common issue. Most Brisbane homes built before 2017 came with ionisation alarms as standard. They look identical to photoelectric models from the outside — you have to check the label to tell the difference.
No alarms in bedrooms
Before the legislation changed, alarms were only required in hallways and on each level. Many Brisbane homes still have this older setup with nothing in the bedrooms. Under current law, that is a fail.
Alarms not interconnected
Having the right alarms in the right places is not enough if they are not linked. An alarm in the hallway that sounds on its own will not wake someone sleeping behind a closed door in the back bedroom. Interconnection is what makes the whole system work as intended.
Removable 9V batteries
The old screw-open battery compartment with a standard 9V battery is one of the easiest things to spot. If you can change the battery yourself, it is a removable battery — and the alarm is not compliant.
💡 Not sure? Take a photo of the back of your smoke alarm and the label. A professional can usually tell from the photo whether it is compliant or needs replacing.

Do not panic. Getting compliant is a straightforward process for most Brisbane homes:
- Get an assessment — a licensed electrician reviews your floor plan and identifies exactly what you need and where.
- Get a fixed quote — no surprises. You know the cost before any work starts.
- Installation — typically completed in one visit. Wireless interconnected alarms can often be fitted without any rewiring.
- Testing and handover — every alarm is tested, interconnection is verified, and you receive documentation confirming compliance.
The whole process for a standard three-bedroom Brisbane home usually takes under two hours. The hardest part is booking the appointment — especially as the 2027 deadline gets closer.

Frequently asked questions
How do I know if my alarm is ionisation or photoelectric?+
Check the label on the back of the alarm. It will state the sensing type. If you cannot find a label or the text has faded, the alarm is likely old enough to need replacing anyway. You can also check for a small radioactive symbol — ionisation alarms contain a tiny amount of radioactive material (Americium-241) and may display this symbol.
Does a study or home office count as a bedroom?+
If anyone regularly sleeps in the room, it should be treated as a bedroom for compliance purposes. The legislation refers to rooms used for sleeping, not what the room is labelled on the floor plan. A study with a sofa bed that guests use regularly would typically need an alarm.
Can wireless alarms really interconnect properly?+
Yes. Modern wireless RF interconnected smoke alarms are fully compliant under Queensland legislation. They use radio frequency to communicate, which means all alarms in the home sound together without any cabling between them. This is particularly useful in older Brisbane homes where running new wires through walls and ceilings would be impractical or expensive.
What is the deadline for owner-occupiers?+
1 January 2027. This is the final phase of Queensland’s smoke alarm legislation rollout. Rental properties and homes being sold have already needed to comply since 2022. The 2027 deadline applies to owner-occupied homes that have not been sold, leased or substantially renovated since the law was introduced. Read our full QLD legislation breakdown for more detail.
