Does anyone have any experience programming a 4204 relay (4 relays)? I want to hook one up to my Vista 20P panel and have it open/close relays based on system states. Those relays would be wired to door/window contact sensors like my connected smokes are. The idea is to have the 4 relays trigger …

Ademco 4204 relay module (for Vista 15P and 20P)

What about the AD2usb, does it function the same way as the AD2Pi?
