Installing the NC-2000 Patient Unit
3.5 Paging Input
The paging input terminal, CN2, is located on the keypad circuit board below the main circuit
board (see Figure 16).
Figure 16 External paging input terminal CN2
When connecting to an external paging amplifier, follow these guidelines:
•
Use a dedicated pair of 22AWG wires from each Patient Unit to the paging amplifier.
•
If your paging amplifier outputs 25 V, connect the outputs on the paging amplifier to the
LOW and COM inputs on CN2.

Do not overtighten the screw terminals.
