I can’t follow all the wiring...it seemed to me that the Valcom is providing the power to the speakers and also makes the tone when intercom is used.

As for why I want a computer for my bells — right now a relay that is connected to the Valcom does not allow me to do complicated schedules like every other day bells combined with other schedule.


Software scheduler on an old computer is much cheaper and easier to work with than any relay I could find that would let me do the schedules I need.

I would love to get rid of the Valcom completely but I just can’t follow the existing wiring well enough to get rid of it.
