There was at least one if not two Franklin County CD sirens (Both Thunderbolt 1000’s, 1952 units) that were Federal Enterprises units. These units came from Cleveland/Cuyahoga County after CD was closed in the city and county in 1972 and all sirens were gone by 1973 (save for a couple suburbs that ...

PPL Susquehanna Steam Electric Station in Berwick, PA once had a system of Thunderbolt 1000s, and some of which had some unique jailbar grilles, in which the jailbars only went horizontal. This is the only picture I could find of one. Also unlike a normal jailbar thunderbolt, these Thunderbolts wer...

By the way, the Thunderbolt in that video almost definitely had stripes at one point, since it was likely installed around the same time as the infamous Smiley Middle School bumblebolt.

On my phone I can see the bars. She’s a jailer. Too bad you can’t hear the pulsate though... and they didn’t switch the leads because it was replaced by a 2001-130. It’s still there it’s just not connected (according to a couple of years ago...) and I think if someone gets her down they can keep ‘e...

My first attempt at a proper siren video. Feedback appreciated!

Kiron, Iowa has a Thunderbolt 1003. it may have been removed.

I would recommend checking the map before suggesting locations. Most of the stuff you and Phone Goat have notified us about is already marked.

More news The siren was installed in 1956. it is a Federal Sign And Signal Thunderbolt 1000A. There's no way that Thunderbolt was installed in 1956.

That makes at least two nuclear plants that are known to have had ACA products, with the other being Cook Nuclear in Michigan. If there are others, I haven't heard of them yet.

The Crystal River Nuclear Plant in Florida had various ACA sirens, including a few Hurricanes.
