The Siren Board

I'm dieing to know. 8)

You talking large area warning or vehicle?

Large area warning, my vote, the Federal Signal Thunderbolt Dual Tone.

Vehicle, my vote for electronic, the Federal Signal PA-300. Electromechanical, the Federal Q.

The Code 3 mastercon isn't bad either!

A firetruck isn't a firetruck without a Q. I still say and feel that the mechanical siren is more effective overall than the electronic siren whether it be a Q, C or 28. The chrome version of a 28 was the model 66.

Mine would be the Model 77, because it is a dual-tone vehicle-siren.

A single dual-tone siren?

Or was it two separate sirens?

My father's fire department's brand new 1959 Mack fire truck had dual sirens.
Was it two separate sirens, or one with two tones and an identical looking dummy on the right side with same red light?

I had a friend that had a dual tone model 77 on a 1965 Cadillac combination. It was amazingly different in sound when coming at you. It didn't seem as piercing as the monotone but it was loud and effective. His also had a brake on it as it was a long coasting type siren.

For outdoor warning, the British bench grinder and the 2T22.

For vehicles, the Q2B and the Model 76/77.

For buildings, the Model A, or anything that doesn't use a high-pitched piezo sounder or an overdriven mini-speaker.

Federal Models 76 and 77 had a stacked rotor which generated a 2nd interval dual tone. I heard only one of these, used by the fire department in Puebla, Mexico, and the reverberation off surrounding buildings is awesome. The 2nd interval has a very strong beat, giving it rather frightening quality. In the sound file collection of this site is a recording of one being run off a large transformer.

I don't think that I found one. Adam has posted the recording on the old board, which is the only place in which I found the recording.

Outdoor warning siren- T-1000, and not just because I own one, I think they sound way spookier than the 1000T, and they can blow out your neighbors windows (not that I've ever done that...yet) !
As far as vehicle sirens go, that "timber wolf" siren looks promising. High power, low weight and current draw sounds good!

What is difference between 1000T and T1000?

I question Timberwolf's dB output accuracy.
How can they do it with 1/4 amperage draw of Q?

Does JMEV greatly exaggerate the Q's current draw as 250 amps?
