You do realize that the Model A and Model J are identically the same as far as noise-making parts are concerned, right? The only thing that differentiates the Model A and Model J is that the J has a heavier-duty motor in it to be able to withstand applications that require prolonged or continuous use of the siren whereas a standard Model A's motor would burn out. It's the same situation with the Model D and Model L; the L is just a Model D with a heavy duty motor. Toward the end of the Model J's production, they used the exact same projector and intake as the then-current Model A, so you could no longer visually tell them apart as you could with the earlier models that each had their own different projectors and intakes. The one thing I do agree somewhat on is that he should try it on a lower voltage (120V) first to see what it does, and if it sounds like it's running slow and not getting up to the speed of a normal Model A, then it's a 240V model.TrainsAndSirens1 wrote:This siren is actually a Model "A". I'm serious. Federal added the wrong ID plate (tag) on this siren when it was manufactured. Do not run this siren on 240/250 volts. This one will run on 120 volts only. Also, I'm guessing this one was made in the 1970's.
