How Often Should Smoke Alarms Be Replaced in Victoria?
Smoke alarms are one of the most important safety devices in any home. They provide early warning in the event of a fire and can save lives by giving occupants time to escape. In Victoria, there are strict requirements around smoke alarm installation, maintenance, and replacement — particularly for rental properties.
Below, we explain how often smoke alarms should be replaced in Victoria, why replacement matters, and what homeowners and landlords need to know to stay compliant.
How Long Do Smoke Alarms Last?
Most smoke alarms have a maximum lifespan of 10 years. Over time, the sensors inside the alarm become less effective, even if the alarm appears to be working.
In Victoria, smoke alarms must be replaced every 10 years or sooner if they are faulty, damaged, or not compliant with current standards. The manufacture date is usually printed on the back of the alarm and should be checked regularly.
If you’re unsure how old your smoke alarms are, it’s safest to have them inspected by a licensed electrician.
Victorian Smoke Alarm Requirements
Victorian building and safety regulations require smoke alarms to be:
Installed on every level of the home
Installed in hallways outside bedrooms
Connected to mains power (for most properties)
Equipped with battery backup
Rental properties have additional compliance requirements, and landlords are responsible for ensuring smoke alarms are installed, working, and up to date at the start of every tenancy.
When Should Smoke Alarms Be Replaced?
Smoke alarms in Victoria should be replaced if:
They are 10 years old or older
They fail testing or produce false alarms
They show signs of damage or discolouration
They are not compliant with current standards
They are battery-only alarms in properties requiring hardwired units
Simply replacing batteries is not enough if the alarm itself has reached the end of its service life.
Smoke Alarm Requirements for Rental Properties
For rental properties across Melbourne’s South Eastern Suburbs, smoke alarm compliance is especially important. Landlords must ensure:
Smoke alarms are correctly installed before a tenancy begins
Alarms are in working order at the start of each new lease
Faulty or expired smoke alarms are replaced promptly
Failure to comply can result in penalties and may also affect insurance coverage in the event of a fire.
Why Professional Smoke Alarm Replacement Matters
Smoke alarm installation and replacement should be carried out by a licensed electrician. This ensures:
Correct placement for maximum effectiveness
Compliance with Victorian regulations
Safe connection to mains power where required
Proper testing after installation
Incorrectly installed or outdated smoke alarms may not activate in time during a fire, putting lives at risk.
Signs Your Smoke Alarms May Need Replacing
Some warning signs include:
Frequent false alarms
Chirping even after battery replacement
Alarms that fail testing
Alarms older than 10 years
If you notice any of these issues, it’s best to have your smoke alarms assessed and replaced if necessary.
