    Default Q2A vs. Q2B

    I've got a question, hopefully someone knows the answer. What's the difference between a Q2A and a Q2B siren? besides the lettering

    Why i'm asking this is because we have 2 engines that have Q's. One is a Q2A and the other is a Q2B. I don't notice a difference in sound.

    I went to the Federal Siganl website, and I found no mention of the Q2A. There was a Q2B and a E-Q2B. The Q2B being mechanical, and the E-Q2B which is electronic.

    If I were to make a ques I would guess that the Q2A would ne an earlier model of the Q siren but I have nothing to back that up with as I have never heard of it.

    Who cares what it is called, as long as it sounds loud, cool and gets people out of the way fast.

    The Q2A is just an earlier version and most of them didn't come with a brake on the, Hense the B in Q2B. However most departments installed an aftermarket Brake because without it there is a high electrical draw and it makes it hard to work or stand in front of the apparatuas when the Q is winding down.
