The City of Detroit has installed 56 new digital warning sirens throughout the city, covering each of the city’s 7 districts. This is a historical accomplishment for the city of Detroit.  After several years of closing fire stations, schools, and recreation centers, the city had a total of approximately 22 sirens in use; however, the majority of these sirens have been non-functioning since 2001. 

The sirens are tested the first Saturday of each month at 1 p.m.  The sirens serve as a warning system for residents.  If you hear a siren,outside of the monthly test time tune in to a local television or radio station for any emergency alerts
