My current system is a Ademco Vector 3000 (#4153). This utilizes a polling loop but it looks to me to be slightly different than the polling loop used in the Vista 128BP. The 4153 has the pooling loop hooked up as follows: The pooling loop wires labeled "out" are all hooked up to terminal 1 and 2 on the panel. The polling loop wires labeled "return" are all hooked to a4152 add-on circuit board, which as I understand gave the pooling loop a Class A designation. I do not see such an option on the new Vista 128BP for something like a 4152 , so I am unsure where the return wires are to be hooked up.
Is it possible to set up the Vista 128BP with a Class A designation? If so, what do I need. If it is not possible where do I hook up the return wires from the polling loop that labeled return?
Thanks for any suggestions.
