As fall temperatures drop and rainy weather sets in, many homeowners may be preparing to turn on their heaters for the first time in months. Fire safety officials are reminding residents to check and clean their smoke detectors before doing so.

Dust and cobwebs that accumulate during warmer months can be stirred up when heaters are activated, potentially triggering false alarms.

Regular maintenance can help ensure smoke detectors function properly and reduce the risk of nuisance alerts.

How to clean a smoke detector

• Remove the device from the ceiling or wall.
• Unplug the power cord.
• Remove the batteries.
• Use canned air to gently spray the unit.
• Wipe the exterior with a clean rag.
• Replace the batteries.
• Reconnect the power cord and reinstall the device.

Smoke detector maintenance tips

• Clean detectors at least twice a year.
• Test the battery monthly and replace it annually.
• Replace the entire smoke detector every 10 years.
