I want to hook up the chimes I installed in my condo so they ring when
someone pushes the button at the entrance to my complex.

I *think* I've identified the 5 terminals on the inside of the
intercom in my unit, they are: Red/Black=Buzz in,
White/Black=Listen/talk and Blue=doorbell; and there's the rub, there
is only one terminal that appears to make the buzzer work.
