Why yes it is.

Found a video from Contra Costa Sheriff with a siren. Is this an ACA Cyclone or that H.O.R from page 293?[youtube]https://www.youtube.com/watch?v=MzycMnlLPyo[/youtube]

What do you want to know, what the siren in the video is, or the thing with shrouds on it on 293? Your wording doesn't point me in any direction, but:

If you want to know what the siren is in the video, then it's an ACA Cyclone 125 (and I'm guessing you know that).

Because of this, the siren with square shrouds on 293 isn't going to be a Cyclone.

Hope that helped.

He was asking if the siren heard in the video is that Cyclone or the HOR with the square shrouds

Still can't see the Cyclone/HOR similarity though. Oh well... might be me.

Alright, here’s a tough one. It’s not an HOR or B&M.. Scream Master is a possibility. It’s 8/10 port (yes, 8/10), has a 10hp Sterling Electric motor, and it’s a vertical siren. It’s standing on legs and has no indication of anything that could possibly make it a horizontal siren. The stators have slots similar to that of some of Federal’s sirens, but the rotor (and pretty much every thing else) does not look like it’s Federal. Here’s some photos:

Remember seeing a discussion about it on Discord with the author of the photos and a few others. Don't know what the outcome was but I have a feeling that they weren't sure either.

Those are my photos. I took them during my two visits to B&M. And no.. it’s not a B&M.

Oh! Now I remember! Who said it was a B&M? As I didn't! I was asleep!

[FS Rotor]

Nobody, I just want to prevent that in advance because it is at the B&M shop. The owner (Kevin) said it’s not a B&M, and showed me a B&M AR-20 for comparison.

As it's dual headed and dual tone I think it rules out ScreamMaster as all I have seen on them are single chopper/stator assemblies with the choppers and stators being single tone.

I'll tell you what it does look like, a HOR. That video of the Pheonix AZ siren auction showed a Si-Rex that has that lip on the intake. On the Super Si-Rex sirens that were also there the choppers looked exactly like the one seen in the photos. Thing is, I don't think HOR made any sirens with 8 ports, and, You'd see a nametag on it saying what it's called. I think it looks similar to a HOR but then again I think I may be the only one.
