Installing and maintaining smoke alarms

For questions or concerns relating to smoke detection, contact the Inspections Division by email or by calling (651) 714-3543.

Smoke Detectors:
Some First Alert® smoke detectors and combination smoke/carbon monoxide alarms were recalled in May 2006 due to rapidly draining battery power.

The Minnesota State Fire Marshal recommends that smoke detectors be replaced when they have been in use for more than 10 years or when the alarm fails to respond to testing. Other conditions also may cause an alarm to be less effective.
