I'm sure it's a very common newer model
Curious if anyone can identify, I can tell it rotates

Yup federal 2001 SRN. No belt driven rotator (SRNB).

That one's part of the Catawba Nuclear siren system, there's over 75 of these in the 10 mile radius. They're tested every quarter on the second wednesday at 11:50 AM.

The one in the pic is a 2001 SRN and the video TurbopropPilot shared was a 2001-130 (130 DB). The SRN and SRNB are just a bit quieter like the difference between the A1 and the 5M A2 blower on a Thunderbolt.

It is a belt driven rotator. The SRNB has a more square rotator.

Is that right? I though the B in SRNB stood for belt in the rotator? Keep in mind I heard this from a youtube user. (No it wasn't Ian or Jeb.)

[mrboojay]

Yes, the "B" stands for beltless.

[coastalsyrolover]

Oh B stands for beltless... Okay got that a bit mixed up.

[Jim Z]

I thought it just meant "Revision B."

[coastalsyrolover]

Lol nope. It's the rotator belt.
