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.
For questions or concerns relating to smoke detection, contact Inspection Services by email or by calling 651-714-3543.
