Pair A connects the 4001 NAC to the 4003 and is used for automatic alarm
activation and for 4003 supervision. Pair B connects to the Initiating Device
Circuit (IDC) from the 4001. It is used for 4003 manual alarm activation, and it
turns on strobes, city connect, or other functions wired directly to the host panel.
