Note 1: The denotion ”1 and 14”, “2 and 15” etc. used in the table indicates, that the two
pins are internally connected. This will ease cabling when the unit is not an
endpoint.
Note 2: The cable shield must be connected only to the Alarm Panel that powers the
interface (Alarm Panel 1 in the wiring diagram). All segments of the interface
cable must have connected shields”
