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 so that the entire unit is replaced 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 by a licensed electrician.
