Video from the Long Island Fire Alarm site.

I found this video on the L.I.F.A. board.
Some people there claim it to be a Sterling type of siren, while others think that it is a dual-tone Model A. I think that it is an H.O.R. type, possibly a Super Sirex, with a seven-to-ten port-ratio.

Here.

Sounds pretty wierd. It sounds like it uses the same port ratio as the HOR siren in Hamilton, OH.

It must have the same type of rotor, if not similar, as the H.O.R. model that Greg N. recorded sometime back, seeing that there is only space for one rotor in that siren, because all I see are three louvers.
