Simple care. Reliable protection.
Smoke alarm maintenance and testing
Regular testing and gentle cleaning help smoke alarms work correctly and can reduce nuisance alarms caused by dust, insects and environmental conditions.
A practical maintenance schedule
Test every alarm
Press and hold the test button until the alarm sounds. Check that interconnected alarms also activate.
Clean gently
Vacuum around vents using a soft brush attachment. Wipe the outside with a soft dry or lightly damp cloth.
Full system check
Confirm manufacture dates, locations, power indicators, alarm operation and interconnection across the dwelling.
Replace the alarm
Smoke alarms must be replaced when they reach 10 years from manufacture, or sooner if faulty or damaged.
Cleaning and safety
- Never paint, cover or remove a smoke alarm.
- Do not blow compressed air into the alarm.
- Do not spray cleaners, insect spray or chemicals near the alarm.
- Keep vents clear of dust, insects and cobwebs.
- Report persistent chirping, damage or unwanted activations promptly.
Common causes of nuisance alarms
Dust, small insects, humidity, steam, cooking fumes, strong airflow and poor placement can affect an alarm. Alarms near kitchens, bathrooms, laundries, garages, ceiling fans or air-conditioning outlets may need closer assessment.
A brief chirp does not always mean the alarm is faulty. Many models chirp every 32–60 seconds for a low battery, end-of-life warning or fault condition. Check the product instructions and the alarm’s indicator lights.
For rental properties
Tenants should test and clean alarms at least every 12 months, report problems and allow access for installation or maintenance. Smoke alarms must not be removed, covered, painted or deliberately disabled.
