How do I keep my smoke alarm working?
If you have a smoke alarm with batteries:
  • Smoke Alarms powered by long-lasting batteries are designed to replace the entire unit according to manufacturer's instructions.

  • In standard type battery powered smoke alarms, the batteries need to be replaced at least once per year and the whole unit should be replaced every 8-10 years.

  • In hard-wired, battery back up smoke alarms, the batteries need to be checked monthly, and replaced at least once per year. The entire unit should be replaced every 8-10 years.
Helpful Tip
  • Pick a holiday or your birthday and replace the batteries each year on that day.

  • If your smoke alarm starts making a "chirping" noise, replace the batteries and reset it.
