Battery Replacement and Testing

Keeping smoke detectors in good condition is easy. Always follow the manufacturer's instructions.

Battery Replacement

  • Be sure to replace the batteries twice a year or as needed
  • Most models will make a chirping, popping or beeping sound when the battery is losing its charge. When this sound is heard, install a fresh battery, preferably an alkaline type

Testing

  • Test smoke alarms every 30 days by releasing fake smoke from a can or pushing the test button located on the alarm
  • Test smoke alarms if you've been away from home

Maintenance

  • Replace bulbs in photoelectric alarms every three years or as needed. Keep extras handy
  • Clean the detector face and grillwork often to remove dust and grease
  • Never paint a smoke detector as it will hamper its function
  • Replace smoke alarms after 10 years of use
  • The Fire Department will check smoke detectors at your request
