The only mechanical vehicle siren produced by Federal is the Q2B. The old models are only available used, if you can find them. BTW, here's a picture of the 28. http://www.sirenman.com/complete/s21.jpg Some FDNY apparatus still have these-- they moved them from unit to unit as their apparatus was re...

Why is this page so wide that one must horizontal scroll to read it? Other pages are not too wide. It is due to the picture being too large.

We had a Federal Q2B on one of our ambulances back in the mid 70's (all caddies) in Cherry Hill, NJ. The ...

There is a Whelen dual tone siren on one of the ambulances in the district I work in as a paramedic in Eastern Long Island, NY. They just got it a few months ago.

In New York the Vehicle and Traffic rules clearly state the candle power allotted to Volunteers. It's something ridiculously low, like 30 CP(read: Christmas Tree Lightbulb!) I'll see if I can dig it up; I've read it many times over the years. The visibility level in terms of feet that Robert refers ...
