Eclipse Median Instruction Manual 1 - 5
The Median houses any of the following interfaces modules:
• FOR-22 . A two-channel, universal 4-wire interface with transformer
isolation, opto-isolation for logic input, and relay contacts for relay
out.
• CCI-22 . A two-channel, isolated translator of 4-wire audio from the
matrix to two-wire intercom circuits, such as Clear-Com party line
products.
• TEL-14 . Allows two standard 2-wire POTS telephone lines to connect
to matrix ports.
• RLY-6 . Provides six relays that can be wired for general purpose use
and controlled directly from the matrix.
• GPI-6 . Provides a method to read external switch closures and
control voltages and translate them to operations in the matrix.
• AES-6. Provides a method to connect third party and digital devices
to the matrix.
You can add additional interfaces to the Median via separate interface
module frames: the IMF-3, IMF-102, and DIF-102. See the manual
Interface Module Frames in the Eclipse manual set for more
information.
Note: The DIG-2 and VeNiX (ISDN) modules are not compatible
with the Median frame format.
POWER SUPPLIES
The Eclipse Median has two Euro Cassette power supply units that
you can easily install or remove as needed. One power supply unit can
power an entire matrix; the second unit provides a backup in case of
failure or damage to the first unit.
In addition, the two supplies have separate IEC connectors to AC
mains, and are designed for completely automatic and transparent
changeover between supplies in the event of a power outage in one of
the AC mains circuits.
An over-temperature sensor is connected to both an audible failure
alarm and a warning light, allowing you to diagnose and correct any
power anomalies while the system remains operational.
MVX REAR-PANEL CONNECTORS (“PORTS”)
The MVX rear-panel RJ-45 connectors are called “ports.” You connect
shielded category-5 cable to a “port” to carry signals from the Eclipse
Median circuit cards to connected remote intercom panels or
interfaces.
