Hook it up like any other siren, with the heavy wire going to positive, and grounding the frame. The main difference is that you have to apply power to the positive wire of the brake to release the brake, where as on the Federal sirens, you apply power to the brake to engage the brake. The reason for this is that the siren will start to howl as you go down the road, without the siren in use, if the brake isn't engaged. The brake is always engaged, until you apply power to it. I have posted the Siren wiring diagram that is on the B&M Siren website. There is also a maintenance manual on the website.

Thank you Paul.
Would I need to have the solenoid just to see if it spins when power is put to it and what can I ground it to if its sitting on a work bench ?

Using jumper cables and a fully charged battery, clip the positive cable to the cable coming out the bottom of the siren, along with the 12 gauge wire from the siren brake. Then clip the negative battery cable to the siren base, and then toch it to the negative terminal of the battery. It should come to life. Might be best if you have a helper to hold the siren from jumping off the work bench when it is grounded.

That sounds easy enough....I will give that a try and I will have a handy dandy wife to assist in securing the siren itself.
Thank you again,Paul !

As always, I agree with everything Paul said - HOWEVER - I suggest you provide your wife with some hearing protection.
If the siren works, and you decide not to use any hearing protection yourself, you may have a valid excuse to claim you can not hear what she is asking you to do!

Sorry,say again ?
I have a hard time hearing because I sat UNDER Super Chiefs and Federal Q sirens for the better part of 14 years so hearing is not what it used to be !:confused2: :yum:
