I have a customer who already has Contact Closure 1 setup and working on their PARTNER system. They have recently installed a second door lock/striker on another door in their office. My question is, what all do I need to do to setup the second Contact Closure? I already have a Contact Closure 2 button programmed on the receptionists phone and have a RJ45 with two pair going into the CC port on the processor, but I am uncertain with how the termination needs to happen on the striker "amp/power" box. Does the second Contact Closure come off the second pair of the RJ45? How does it need to be terminated? Any help would be greatly appreciated. Thanks in advance.
