How do I test my home's smoke alarm?

The increased risk of fires during winter means we need to be extra vigilant in our home fire safety practices and fully the utilise the protection systems already on hand, such as your home's smoke alarms.

Electro Systems electricians and the Queensland Fire and Rescue Service recommends that you test the smoke alarms in your home at least once a month.

Smoke alarm testing

How do I test my smoke alarm?

  • Clean the smoke alarm with a long handled broom or the brush attachment on your vacuum cleaner to remove dust, cobwebs, and insect debris all of which can interfere with the efficient functioning of the alarm.
  • Gently depress the test button.
  • The alarm should emit a loud beeping noise.
  • If the sound is not very loud or the beeping is not constant -
  • 9-volt battery powered alarm - replace the alarm batteries and test again. If the beeping is still quiet or inconsistent once the battery has been changed replace the whole smoke alarm.
  • 10-year lithium battery alarm - replace the alarm.
  • hardwired smoke alarm - ask your electrician to check and repair or replace the alarm.

Essential smoke alarm maintenance tips

  • Carry out the smoke alarm testing at least once a month.
  • If the alarm is making a slow warning beep at any time throughout the year this usually indicates that the battery needs replacing.
  • Change the batteries if you haven't done so this year. A two pack of 9-volt batteries costs around $8.00 to $10.00 which is a small price to pay for the protection the smoke alarms offer.
  • If the alarm is more than 10 years old it needs to be replaced.
  • In line with the new Queensland smoke alarm legislation, all new smoke alarms must be photoelectric type alarms.
  • This year marks 20 years since new and renovated homes were required to be fitted with a smoke alarm in QLD. If your home's alarms have not been updated since then they potentially will not activate in the event of a fire.
  • Other than routine testing any maintenance or repairs needed on mains powered smoke alarms must be carried out by a licenced electrician.
