Hi Sam,

I need some calefaction on" buzzers rest on 10VAC" what do you mean?

Also when I do reverse wire the power on the DICM, would I reverse both A and B battery?.

Would I leave the 10 VAC for the audible supply or would I need to make any changes to the audible supply and to the audible supply Ground.


One idea that I was thinking about is to get a spare DICM unit and reverse wire it and only use this unit for the relays. And then have a relay to transfer the Tip/Ring pair to the spare DICM unit and when you done making a section for a relay dial the ext for the return relay to transfer you back to the normal DICM unit.

Thanks Brian
