FS THUNDERBOLT 1000T Siren Test (Alert) - Deerfield MI - 06JUL2024 

Siren location: 43.204, -83.31202
Back at the original Deerfield Township Federal Signal Thunderbolt 1000T for its monthly 1st Saturday at 1pm test (3min alert tone). This Thunderbolt was manufactured & installed back in 1981, and still sounds as fierce as ever. As always, a huge thank you to Tim Reinhardt for keeping this historic siren going strong!
