City of Rochester Hills issued the following announcement on Aug 4.
When there is a fire, every second counts. Smoke alarms are a critical part of fire safety. For those that are hard of hearing, strobe lights or bed shaker devices can be a good alternative.
The Rochester Hills Fire Department has been installing smoke and carbon monoxide alarms to residents, free of charge, for over a decade. If you would like a free smoke alarm or carbon monoxide alarm (if available), please call our Fire and Life Safety Educator at 248-841-2705.
