On the first Wednesday of every month, Hamilton County, Ohio performs a test of their Outdoor Warning Siren System, weather permitting. I was off of work today, so I decided to record the Thunderbolt 1000T located on top of the Salvation Army Building in Norwood, Ohio. If I am wrong, I'm sorry and please correct me, but I believe this to be a 1000T model Thunderbolt. Other sirens heard are Thunderbolt 1000Ts, one of them being located on Montgomery Road near Silverton. During the Attack Cycle, this siren operates correctly, and not all of the Thunderbolts do operate correctly in Attack in Hamilton County. Unfortunately, this siren is scheduled to be replaced later this year with an American Signal T-128, along with the other older sirens in the county. Growl; 1:44, Alert; 4:26, Attack; 6:18
