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.
The Valcom V-99227a is just a tone generator. There is a paging amp somewhere being fed by it. No need to get rid of it.
I'm curious as to what the "relay" is that's triggering the Valcom now. There are lots of different products to trigger bells.
Hal's idea is an interesting one. You can do a lot of cool stuff with Arduino and Raspberry Pi devices, you just have to deal with the learning curve.
