So I got everything swapped out (Brinks 4000A to Vista 21ip) and all is working well. I had a 4-wire smoke and a smoke/heat with the Brinks panel but am looking into 2-wire (2WT-B). I keep reading that these should be connected to each other but the Brinks detectors were set up as separate devices and therefore have independent wiring run from each device to the panel. Could that still work and both can be connected to zone 1? I don’t have the ability to try and rewire everything. If that wouldn’t work, what other options do I have?
