Smoke alarm chirping or beeping
A single chirp every minute or so is nearly always a flat battery or an alarm at end of life. Here is how to tell which, and what Queensland law now requires.
- 5.0 on Google
- 24/7 emergency callout
- Licence 82270
What the beep is telling you
- One chirp every 30 to 60 seconds: flat battery, or the alarm has reached end of life. Photoelectric alarms are generally replaced at ten years regardless of whether they still work.
- Continuous loud alarm with no smoke: usually dust, insects or steam. Bathrooms and kitchens are the usual offenders, and so is a bug that has got inside the chamber.
- Chirping that moves around the house: if your alarms are interconnected, one flat unit can set the others off. Find the one that is actually chirping, not the loudest one.
The Queensland deadline you should know about
Queensland has the toughest smoke alarm law in the country. The Queensland Fire Department states it plainly: all existing private homes, townhouses, units and manufactured homes require interconnected photoelectric smoke alarms by 1 January 2027.
Interconnected means when one alarm detects smoke, they all sound. Photoelectric means the sensing type, not ionisation. The alarms must comply with AS 3786-2014.
If your alarm is chirping because it is at end of life, you are about to replace it anyway. Replacing it with a compliant interconnected system now rather than a single 9V unit is the difference between doing this once and doing it twice.
Where they have to go
On every storey. In every bedroom. In the hallways that connect the bedrooms to the rest of the house. If there is no hallway, between the bedroom and the rest of the dwelling. If a storey has no bedroom, at least one alarm in the most likely path of travel out.
If it is a rental
The obligation sits with the owner or the manager, not the tenant. The Residential Tenancies Authority requires the manager or owner to test the alarms and replace flat batteries within 30 days before the start of a tenancy, and states the obligation must not be passed on to the tenant. The tenant's job is to test and clean them during the tenancy and report anything that is not working.

Straight answers
Smoke alarm beeping: your questions
Can I just take the battery out of a beeping smoke alarm to stop the noise?
Please do not. A dwelling without a working smoke alarm is the situation the law exists to prevent, and the chirp is usually a five minute fix. At 3am a chirp is almost always a flat battery or an alarm that has reached the end of its ten years. Put a fresh battery in. If it is a sealed ten year unit, or if it keeps sounding with no smoke in the house, ring us and we will come and sort it. What we will not tell you to do is spend a night in a house with the alarm disabled.
Do I have to upgrade my smoke alarms if they still work?
By 1 January 2027, yes, if they are not already interconnected photoelectric alarms to AS 3786-2014. Working is not the same as compliant.
Does interconnecting smoke alarms mean running wires through the ceiling?
Not necessarily. It can be done by hard wiring or by a compliant wireless link between alarms. On an existing home a wireless interconnect is usually the least invasive option and we will tell you which suits your place.
Can you do the smoke alarms in a whole building at once?
Yes, and for body corporates and agents it works out considerably cheaper than attending one unit at a time. We do scheduled runs across whole buildings and whole rent rolls.
