What is this????

[Chiz]

I found a video which was filmed in New York City and I'm wondering if the noise is a siren and if it is a siren what is it for and what type of siren is it? http://youtube.com/watch?v=VRp1RIUeRaY

Whatever it is, it is definitely a Federal Signal product. They love that "F" note and have been using it for almost 100 years. "F" for Federal?

Do they have tornado sirens in NYC?

It sounds rather like a Modulator.

[Chiz]

strange why would New York City have a Modulator?

[SirenMadness]

I am not certain that a Modulator is being heard. I heard on the L.I.F.A. board, which is currently not in service, that some municipalities are replacing their old sirens with Modulators.

Sounds like a Federal Model 5 or STH

He said in his comments "lol I live right outside New York City, we don't have tornado sirens here. And we weren't under a tornado warning, only a severe thunderstorm warning."...it is prolly one of the towns fire sirens ither going off for a fire or giving a severe weather alert...

Sounds like a Model 1, 5, or Screamer, or an RM-130. I think the Model 1 is the highest pitched, but it could be an STH-10.....

New York City has Tornado/attack sirens. they were used on september 11 after the first attack I heard them on a documentary recently.
