How do I keep my smoke alarms working?
The following tips will help you keep your alarms working:
  • Keep them clean. Dust and debris can interfere with their operation, so vacuum over and around your smoke alarm regularly.

  • People with hearing impairments should install smoke alarms with louder alarm signals and/or strobe lights to alert them to a fire.

  • Replace the batteries at least once a year. Schedule battery replacements for the same day you change your clock from daylight to standard time in the fall.

  • Test smoke alarms at least once a month by using the alarm's test button or an approved smoke substitute, and clean the units in accordance with the manufacturer's instructions.
