Mystery Pulsing siren?

[Mac]

I was talking to my mother about sirens (no, this doesn't happen often), and I asked her if she remembered any sirens from when she was growing up.

She grew up in a town called Ardsley, New York. It was a fire siren that was used to call firefighters- this was in the '60's.

From her description, it wasn't a Hi-lo like I was thinking, but rather an abrupt on-off ? Though she never saw it, she is fairly sure it was a siren. From her description I believe it sounded something like a giant Vibratone horn, so I'm not sure it wasn't a giant horn?

Were there many horns used in fire departments in NY that could be heard 5+ miles away?

The Gamewell Type B (Diaphone) is the first thing that comes to mind. http://hornandwhistle.com/articles1.htm

If it wasn't a diaphone or a tyfon, it could have been a coded siren.

The Ardsley, NY Fire Department has a set of diaphram horns on the roof of the former firehouse. They have been there for quite a while, they never had a siren of any kind (I asked the last time I was there shooting pictures of thier apparatus). The diaphram horns sound very nice... I am told that they have since put up a Whelen to go along with the diaphram horns.

Thank you Dave! I think I posted some pictures of the Wheelen a while ago on here from the other angle- I never thought to look for horns though.
