D
VOX Lights
When lit a VOX light indicates that the audio level on a connected device,
such as an intercom panel or interface, has exceeded a preset threshold. The
threshold audio level is set through the EHX application.
Each of the port card’s 16 green VOX lights corresponds to one of 16 rear-
panel connectors or “ports” to which audio devices (intercom panels or
interfaces) can be connected.
E
Matrix Data Light
The green matrix data light flashes (1: 1 0.5Hz) to indicate successful
communication between the port card and the CPU card.
Status Light
The red status light illuminates to indicate a failure in communication
between the port card and the CPU card.

5.7 Power supplies
The Eclipse HX-Omega has two Euro Cassette power supply units that can be easily
installed or removed as needed. One power supply unit can power an entire matrix; the
second unit provides a backup in case of an equipment failure.
In addition, the two supplies have separate IEC connectors to AC mains power, and are
designed for completely automatic and transparent changeover between supplies in the
event of an outage on one of the AC mains circuits. For this feature to work, each power
supply should be connected to a different AC mains branch.
If the temperature inside the Eclipse matrix exceeds a threshold, both an audible alarm and
a warning light switch on, allowing the system operator to diagnose and correct power
anomalies while the system remains in operation.
Eclipse HX-Omega matrices may be fitted with XP (part 740101Z) or Power-One (part
720379Z) power supply units, depending on the date of manufacture.
The different types of power supply units must not be mixed in an Eclipse
HX-Omega matrix; if one of the pair of power supplies is replaced it must be
replaced with the same type of power supply unit. If this is not possible both
power supplies must be replaced with power supply units of the same type.
Power-One power supplies are identified by the part number on the front of
the unit; XP units do not have a part number on the front of the unit.
