The third siren I found was my favorite find of the day. A Darley Model 5 on top of the Tuscumbia Fire Department in Tuscumbia, AL. I asked a fire fighter if it still works and he says it does and it's used as a tornado siren.

When I was heading back home, I spotted a Modulator 4016 near a TVA Steam Plant. The siren is rather low mounted.
