phone, check the polarity and plug a two pair modular cable into the connector on the KSU
marked DOOR1 or DOOR2 and connect the cable to the terminal of the door phone as shown
in Figure 2-20.
To connect the customer-provided electric door lock unit for control of the door lock release
mechanism, plug a one pair modular cable into the connector on the KSU marked LOCKER1
or LOCKER2.
