Be alert to smoke alarm faults and age
If your smoke alarm is turning a yellow colour, it is a sign the unit is ageing and needs replacing. The same applies for smoke alarms that continually make a ‘chirp’ sound, as this is a sign the battery has stopped working and the unit needs replacing.
Finally, if your smoke alarm keeps activating for no reason, it is time to replace the unit. As smoke alarms age, they may become particularly sensitive to dust particles in the air. So, as well as regularly cleaning smoke alarms, be mindful of their age too.
Test the smoke alarm battery
The CFA recommends testing the battery each month by pressing and holding the smoke alarm's test button until it beeps three times. If there are no solid beeps, or the smoke alarm sounds laboured when testing, it can be a sign the battery needs changing.
If you’re unsure how your to install or charge a smoke alarm yourself, you can get a qualified professional to assist.
Replace the smoke alarm or battery
All smoke alarm units need replacing every 10 years with the most advanced model available, which is currently a hard wired, interconnected smoke alarm.
If you have a 9-volt battery in your smoke alarm, the battery needs replacing every year.
Smoke alarms and rental properties
Regular smoke alarm checks should be conducted in rental properties to ensure safety for tenants. Rental property owners must ensure their property meets the legal standards for house safety.
A Smoke Alarm Safety Check can be added to a rental property inspection. The check includes an assessment of all smoke alarm units, their positioning, cleaning and testing to ensure your home is safe and liveable for you and your family.
