I think the low pitched siren might be a Whelen or T-128, and the high pitched siren might be an STH-10 or Model 5.

That might be a very cool looking telecommunications or radio tower. A far cry from the typical ones with the exposed equipment boxes.

Too bad they weren't painted green or brown to blend in with the trees.

That's because the SD-10, Allertor, and Penetrators used 9/12 rotors.

Basically, it's a smaller version of the T-128, with a smaller sized motor/chopper, and as the name suggests, produces 125dB at 100 feet.

Glad that they went with better quality Modulators, and not the dreaded low quality ATI sirens. :D

Very nice video, it sounds more like a Federal EOWS612 rather than a Whelen WS3016 siren.:D

I would agree with you with Sentry Siren for mechanical sirens, and as with electronic, that would go to Whelen.
