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.
