# Smoke Detectors, Battery Operated

Most smoke detectors on campus are wired devices, reporting to a central fire alarm system. In some instances, battery-operated devices have been installed. Facilities & Operations will replace batteries in smoke alarms when needed at Burnham House only.

Battery smoke alarms installed by departments, schools and colleges in various areas (kitchenettes, labs, etc.) are not F&O-maintained. Facilities & Operations can maintain these devices at customer expense.

To request service, call the Facilities Service Center at 734-647-2059 or visit [requests.fo.umich.edu](https://requests.fo.umich.edu).
