Table 1. Network Wiring Recommendations
For best network performance, one of the suggested cables
should be used. If the specified cable is not used and
communications problems occur that require troubleshooting
assistance, additional charges for support may be assessed.
1.
All low voltage wiring is Class 2.
2.
All low voltage wiring must enter the cabinet from the low
voltage section of the enclosure.
3.
All low voltage wiring must be run in separate conduit from
line voltage wiring.
To network Room Controllers together:
1.
Select end panels to establish the beginning and end of the network
2.
The end panels will have the network termination jumpers installed and the panels in between will have them removed.
