Just curious if anyone knows the ring voltage that comes out of the ACS system extension ports? I have tried a Wheelock Telbel 592 18-48V ringer bell and I have also tried a Wheelock Telbel 593 which is a 90v ringer bell. These bells have a RJ-11 port and operate on one pair and are line powered but I am not having any luck with getting them to ring correctly. The 592 (18-48v) rings constantly and the 593 (90v) barely rings. So I assume the ACS ring voltage is actually somewhere between 30-90v?
