The Siren Board

Sorry for the bump.

I'm pretty sure the 612 is a Decot. I remember seeing a picture of a Decot on top of a building in St. Paul MN. St. Paul had around 20 of those Decots before they were replaced with Thunderbolts and STH-10's. The location of the Decot in the picture was unknown.

Great find. The class 615 must also include T-Bolts since we know Tampa had that model although I wasn't sure all the sirens were T-Bolts. I did not know Hillsborough County also had sirens I'm assuming these were operated by fire districts at the time.

In one of the pages I found the town of Morton Grove Illinois which is were I live. It says that Morton Grove had Only one siren, 617 which is a thunderbolt 1000t because that is the only siren left from our old system. Thanks for this info, now I know that my towns complete old system.
