A working smoke alarm can be the difference between a close call and a catastrophe. Yet thousands of Melbourne homes have alarms that are out of date, incorrectly placed, or no longer compliant with current legislation.
Smoke alarms degrade over time. Sensors lose sensitivity, batteries fail, and older ionisation-type units can miss the slow-burning fires most common in residential properties.
Our smoke alarm service covers everything from a single detector replacement to a full home system upgrade, so you’re protected and compliant.
O’Shea Electrical prioritises quality smoke alarm installation and testing for residential premises.
Prompt detection is crucial to prevent fire-related disasters.
Victoria's smoke alarm laws have tightened significantly in recent years, and non-compliance can affect your insurance and your safety.
Key requirements under the Building Regulations 2018 (Victoria):
If your home was built or renovated before 2021, you may still have older alarms that don't meet current standards. Our smoke alarm electricians can inspect your property and advise on what's required.
Choosing the right smoke alarm matters. Not sure which type suits your home? Our smoke alarm electricians will assess your property and recommend the right solution. Here's a quick breakdown of your options:
The type required under Victorian legislation for new installs. Photoelectric alarms use a light beam to detect the smoke particles produced by slow, smouldering fires - the kind most likely to start in bedrooms and living areas. They're faster to respond to this fire type and produce fewer nuisance alarms from cooking steam.
Older technology that responds faster to fast-flaming fires but is significantly slower to detect smouldering fires. Ionisation alarms are no longer compliant for new installations in Victoria and should be replaced with photoelectric units.
Required for new builds and major renovations since 2021. Wired directly into your home's electrical system with a battery backup, these alarms communicate with each other - so an alarm triggered in the garage wakes you up in the bedroom. Installation must be carried out by a licensed electrician.
For homes not requiring a hardwired system, a sealed 10-year lithium battery photoelectric alarm is a reliable option. The battery lasts the life of the alarm. No annual battery changes, no flat batteries at 3am.

Hard-wired alarms for buildings post-August 1997; battery-powered for older structures.
Smoke alarms must be replaced every 10 years from the date of manufacture (printed on the unit), or sooner if they fail to function correctly during testing.
If you’ve moved into a home and don’t know the age of the alarms, replace them. It’s a low-cost safety measure with no downside.
Any hardwired or hardwired interconnected smoke alarm must be installed by a licensed electrician. Battery-only alarms can legally be installed by a homeowner, but hardwired systems, required in all new builds and major renovations since 2021, are not a DIY job.
Victorian regulations require alarms in every bedroom, in hallways between bedrooms and the rest of the home, and on every storey of the property. Alarms should not be placed in kitchens or bathrooms, where steam and cooking fumes can trigger false alerts. Ceiling mounting is preferred; wall mounting is only acceptable where ceiling mounting isn’t practical.
Test monthly by pressing the test button until the alarm sounds. Clean the unit every six months using a vacuum or compressed air to remove dust from the sensor chamber. Have a licensed smoke alarm electrician perform a full compliance test annually, especially for rental properties.
A single chirp every 30–60 seconds usually means a low or flat battery.
If the alarm is hardwired and still chirping after a battery swap, the unit itself may be faulty and require replacement. Persistent false alarms can indicate a dusty sensor, incorrect placement near a kitchen or bathroom, or an end-of-life alarm.
