How often do you change your smoke alarm?
Every month: Smoke alarms should be tested (by pressing the test button) to ensure the battery and the alarm work.
Every six months: Smoke alarms should be cleaned with a vacuum cleaner. This will remove any dust or particles that could prevent the smoke alarm from working properly.
Once a year: If your smoke alarm has a battery, you should replace it annually. A good way to remember is to change it when you change your clocks at the end of Daylight Saving. If your smoke alarm uses a lithium battery, it is inbuilt into the alarm and cannot be replaced. The entire unit needs to be replaced every 10 years.
Every 10 years: Replace your smoke alarm. Smoke alarms do not last forever and the sensitivity in all smoke alarms will reduce over time. All types of smoke alarms should be removed, replaced and disposed of at least every 10 years.
