Installation
Up to six NC415AV Master Stations may be connected to a single NC120 CE. Connect up to three mas-
ters to each 8P8C jack labeled master station on the front of the NC120 CE.
Multicolor Zone Dome
If desired, a zone dome light (part number LI484P5) may be connected to the NC415AV Master Station
using the 6P6C jack on the back. The zone dome light will illuminate whenever a call is present on the
connected master station.
Note
: Using a LI484P5 reduces the maximum number of NC415AVs on the module.
Use CAT5 or better cabling to connect the LI484P5 to the NC415AV Master Station and wire the 6P6C
with a straight-through configuration. Do not exceed 50 feet of cabling for dome light connection.
Connect Data Bus Wiring
Before connecting the data bus wiring to the NC120 CE Module, check the data bus wiring for shorts.
Connect the positive wire in the data bus cable to the positive terminal on the NC120 CE Module port
and the negative wire in the data bus cable to the negative terminal on the NC120 CE Module using the
included plugs.
Note which station run gets plugged into which CE module port. This information will be needed when
setting up the system configuration.
Connect Master Bus Wiring
Connect the master bus cabling to the ports on the right side of the NC120 Central Equipment Module.
Keep a record of the locations of master stations and their automatically assigned names. Once the sys-
tem is powered on for the first time, go to each master station on the system and touch the
Menu
button
on the home screen, then touch the
This Master
button that appears. The top of the screen will display
the default name of the master station. Note this information, as well as the actual location of the master
station for use during system configuration.
If more than one NC415AV Master Station is installed on a master bus run, use a CT400P5 splitter to
provide multiple connections to a single master bus port. Set the EOL resistor DIP switch on the last
NC415AV Master Station on the cable run to ON as shown in
Figure 4 on page 13
.
Networking Multiple NC120 CE Modules
If multiple CE modules are to be networked together, use the DIP switches on the face of the CE mod-
ules to set unique module IDs for each CE module as discussed in
The NC120 Central Equipment Mod-
ule on page 10
. Once each CE module has been assigned a unique address, connect the CE modules to
each other using the Ethernet jacks on the left side using CAT5 or better cabling terminated using 8P8C
connectors using the T568B standard.
Maximum cable length is 100 meters (328 feet). Extend this distance by placing NC554/8 network
switches every 100 meters. Use NC556 Fiber to Ethernet Converters to extend this distance up to 1,200
meters over a fiber optic connection.
Once the CE modules are networked together, proceed to the Configuration Setup section.
