Smoke alarms wear out. Most manufacturers and the Australian Standard say to replace them every 10 years, and the date is printed on the back of each unit. If yours are yellowed, chirping or older than that, it is time for new ones.

What we install
Hardwired smoke alarms
240V alarms wired into your lighting circuit with a backup battery. They are required in new homes and major renovations, and are the most reliable option for any home that has the wiring for them.
10-year lithium smoke alarms
Sealed battery alarms with a 10-year life and no battery changes. A good fit where there is no existing wiring and the rules for your property allow battery alarms.
Interconnected alarms
When one alarm sounds, they all sound. Fire services in NSW and Victoria recommend interconnected photoelectric alarms, and we can link them with wiring or wireless modules.
Replacement of old alarms
We swap expired or faulty alarms like for like where the bases match, or fit new bases and adaptor plates where they do not, and test the full set when we are done.
Smoke alarm rules in NSW and Victoria
Homes in NSW
Every home in NSW must have at least one working smoke alarm on each level. Landlords must check that alarms are working each year, replace removable batteries each year, and replace alarms before the end of their service life.
Homes in Victoria
Victorian homes need a smoke alarm on every storey, and homes built after 1 August 1997 need hardwired alarms. Rental providers must have smoke alarms checked every 12 months.
Where alarms go
Alarms belong in hallways between bedrooms and living areas, and on each level. We keep them clear of kitchens, bathrooms, air conditioners and ceiling fans, where steam and airflow cause false alarms or slow detection.
Common questions
How often should smoke alarms be replaced?
Every 10 years, or sooner if an alarm fails its test. Check the manufacture date on the back of each alarm.
Why is my smoke alarm chirping?
A single chirp every minute or so usually means a flat backup battery or an alarm at the end of its life. If a new battery does not stop it, the alarm needs replacing.
Can you replace hardwired alarms with battery ones?
Not where hardwired alarms are required, such as newer Victorian homes and renovated homes. We will tell you what your property needs before we quote.
Do you do smoke alarm checks for rental properties?
Yes. We test, replace and record alarms for landlords and property managers, and can combine it with an electrical safety check.
