How do I keep my smoke detector working?

Smoke alarms are very easy to take care of. There are two steps to remember.

  • Simply replace the batteries at least once a year. Tip: Pick a holiday or your birthday and replace the batteries each year on that day. Some smoke alarms now on the market come with a ten-year battery. These alarms are designed to be replaced as a whole unit, thus avoiding the need for battery replacement. If your smoke alarm starts making a "chirping" noise, replace the batteries and reset it.
  • Keep them clean. Dust and debris can interfere with their operation, so vacuum over and around your smoke alarm regularly.
