So recently, a friend of mine found this document detailing the planning for the outdoor warning system for the Columbia Generating Station: https://www.nrc.gov/docs/ML2004/ML20040D343.pdf
In the end they contacted with Whelen and got WS-xxxx sirens, which were later removed and replaced with WPS-2800s. However, in the document on page 12, there is a section about the sound attenuation measurements they were doing, and it says they used a “Raytec Corporation electronic,122 db(c) at 100 feet, rotating type” siren. I can barely find anything on the name Raytec alone, let alone sirens by them. Would anyone have any more info on these supposed Raytec rotational sirens, or know where to find info?
Update: I think I found it! I guess that little misspelling in the document was what was making it hard to find. The Image came from this Reddit post: https://www.reddit.com/r/AirRaidSirens/ ... ame=iossmf
I also found this document with contacts for a bunch of companies: https://www.google.com/search?q=Raytek+ ... F3uGtv_DsM
All the signs seem to be pointing to them being owned by Fluke now. Hopefully more info will surface. It’s certainly a very unique design , I have never seen a diffraction horn type siren with a rotator.

Update 2: here’s why the name seemed so familiar, I guess this was all already known about: https://www.facebook.com/groups/sirenen ... 128753229/

That looks like it was a precursor to Alerting Solutions' rotating HA sirens (pictured below) but only omnidirectional HA sirens still exist

WOAH! That's the first time I've seen one of those things! Looks like ATI made a WS-2000-R.
Also, that Raytek array looks very interesting... would love to see it in action, although they're probably all gone now. Wonder if that oscillates like a Whelen or if it does a full 360.

I doubt there are any rotating ASI sirens existing, and that photo looks very much edited. There are omnidirectional units still active though.

as for the Rayteks, there probably isn't much of a chance of those existing either especially due to its primitive design

From https://www.hoermann-ws.de/en/company/h ... our-sirens :

"In 1979, with the takeover of Raytek, HÖRMANN also opened its first company headquarters in Silicon Valley: HÖRMANN sirens were in the USA. "

This explains why the horns of the Raytek siren look like the horns of the HLS-273 siren. This is like a rotating variant of the Hormann ECL sirens.

Wow, it would be cool to see a video of these in action!
