How does it connect to my system, looking inside the "big metal box" there are lots of connectors, but it dont look exactly like the on in the video for this part. There are 4 wires I need to connect, but where ? Am I supposed to connect them to the 5 standalone connectors far right and what about the phone jack in this part ? In my "box" there are no phone jack since they are supposed to be "hardcoded" into the system according to my previous alarm provider.
The Envisalink connects to terminals 4,5,6 and 7 (from the left). Please refer to your Vista 20P Installation guide and follow the connects as you would a keypad.
