9 Installing an I-Series Intercom Panel
This chapter describes how to install an I-series intercom panel. It also gives wiring
diagrams for the panel’s rear-panel connectors. For programming information, see the
Eclipse Configuration System Manual.
9.1 Equipment Placement
All I-series intercom panels require one rack unit of space (1 RU) in a standard 19-inch
(48.26 cm) rack.
Put all intercom panels at a comfortable operational height. Leave at least 2 inches (5 cm)
of clearance at the rear of the panel’s chassis to allow for cable connectors and access to
the rear-panel controls. For proper ventilation, make sure ventilation openings are not
blocked.
WARNING: To reduce the risk of fire or electric shock, do not expose the unit to rain or
moisture.
9.2 Mains AC Power
Each I-Series panel has an internal power supply, with a removable AC power cord. The
power supply is “universal,” operating over a voltage range of 90 to 245 VAC and 50 to 60
Hz. The maximum dissipation is 40 W.
9.3 Adjustments
No initial adjustments are required to set up the panels other than the standard input level
adjustment made through the Eclipse Configuration System.
9.4 Configuration
Assign each panel’s name and other parameters by using the Eclipse Configuration
System. For instructions, see the Eclipse Configuration System Manual.
9.5 Wiring
I-Series intercom panels use a twisted 4-pair transmission scheme to connect them to the
matrix matrix using the industry standard RJ-45 connector. Refer to Installing an Eclipse
Matrix System: An Overview for connector installation and use, and the type of cable
needed for connection between panels and matrices.
Each pair of the twisted 4-pair wire has the following function:
• Pair 1 transmits analog audio from the matrix port to the panel.
• Pair 2 transmits digital data from the panel back to the matrix card port.
• Pair 3 transmits audio from the panel to the matrix card port.
• Pair 4 transmits digital data from the matrix port back to the panel.
