San Onofre Nuclear Generating Station (SONGS) former mystery/custom engineered siren FOUND!!!!

[FS Rotor]

All of the other Model 120s were scrapped. By the time they were taken down, many of them already had motor problems, bad corrosion, and many other issues. Not very good for a siren that was only 17 years old at the time it was taken down.

Yeah it seems like it. John should have put a motor cover on them. And since they tested them 3 times for 3 minutes every year the sirens only have ran 78 times in total since October 20th 2005 was the last test of them before the Whelen upgrade.

Here is the reply I got from one of the employees that were apart of the Whelen upgrade.


“We brought the old sirens back to site and many were sold off as scrap as they were old and no one made replacement parts for them. I believe a couple were sold off to some unknown communities that were going to try and refurbish them and put them back in service but I don't know if they ever did or who they were.”

We all know some of the STL-10s from the old system went to Curry County ,Oregon ,but If he said they went to multiple community’s some of the sirens went somewhere else as well. The other half of the old system was obviously the Model 120s ,It looks like they’ve been scrapped but it hasn’t been 100% confirmed yet.

Yeah it seems like it. John should have used an AC or DC motor or the motor should have been covered. And since they tested them 3 times for 3 minutes every year the sirens only have ran 78 times in total since October 20th 2005 was the last test of them before the Whelen upgrade.

The motor is an AC motor. That has nothing to do with it. The sirens were there long enough for many parts to go bad. Since many of the parts that needed to be replaced weren’t made anymore, they would have to spend tons of money on custom made parts. And the new parts would go bad the same way the old ones did. The STL-10s were in much better condition and proved to be much more reliable than the Model 120s, despite being older, so some communities in Oregon got them. The Model 120s were scrapped, for tens of thousands of dollars in total.

The STL-10s went to Curry County ,Oregon and I believe another community. Currently getting motors for the 120,and soon will be making the horns and the metal frame that held the horns and rotor ,just waiting to get the dimensions from John.

It hasn't been confirmed completely that the other 120s were scrapped.

Wasn’t there a few sentrys in the old system as well? I wonder what happened to those. I saw you made a thread on that

[Duderocks5539]

I think they were just proposed installation drawings. But IDK.

[Duderocks5539]

I just got the 1 Hp motor for the rotor a week ago. But it was spinning very slowly and humming. So I took it in to a local motor repair shop. Once I get it working then I will work on the blower meaning getting a Motor for that. Once that’s done I will send the drawings into a fiberglass and metal shop to have the horns and frame made. The siren will probably be complete sometime this year ,but it depends on money.

[Duderocks5539]

Apparently its a defective motor from factory. I will half to call the place I got it from and have them send us another one.

[Duderocks5539]

I still have the motor at the shop ,they literally just called me a few minutes ago and told me its defective.
