Is the buzzer for Intercom or CO signaling?

The only time a device will ring continuously is when it has battery and ground applied to both sides.

Do you have a short on the block between power (RB or 18/10V) and the buzzer?

You could possibly have a defective interruptor. I'll have to pull the prints, but you'll need to check where power comes into the interruptor and then where it's supposed to come out. Is power coming out constantly on leads where it shouldn't

It'll take me a while to find the paperwork. Sorry.
