6.2 Door phone and Door Lock Release
System users can communicate with an optional door phone when the NX-DPH/PAGING card
is installed. A maximum of two door phones may be installed per system. To connect the door
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.
