Please read and follow
these instructions
before operating a
FOR-22 dual 4-Wire
interface.
IMPORTANT SAFETY
INSTRUCTIONS
For your safety, it is important to read and follow these
instructions before operating a FOR-22 dual 4-wire interface:
(1) WARNING: To reduce the risk of fire or electric shock, do not
expose a FOR-22 dual 4-wire inteface to rain or moisture. Do not
operate a FOR-22 dual 4-wire interface near water, or place objects
containing liquid on it. Do not expose a FOR-22 dual 4-wire interface to
splashing or dripping water.
(2) For proper ventilation, make sure ventilation openings are not
blocked. Install the FOR-22 dual 4-wire interface according to the
directions in the Installation chapter of this manual.
(3) Do not install a FOR-22 dual 4-wire interface near a heat source
such as a radiator, heat register, stove, or other apparatus (including
amplifiers) that produces heat. Do not place naked flame sources such
as candles on or near a FOR-22 dual 4-wire interface.
(4) Only use attachments/accessories specified by Clear-Com
Intercom Systems.
(5) Unplug the FOR-22 dual 4-wire interface during lightning storms or
when unused for long periods of time.
(6) Refer all servicing to qualified service personnel. Servicing is
required when:
• The FOR-22 dual 4-wire interface has been damaged in any way.
• Liquid has been spilled or objects have fallen into the FOR-22
dual 4-wire interface chassis.
• The FOR-22 dual 4-wire interface has been exposed to rain or
moisture.
• The FOR-22 dual 4-wire interface does not operate normally.
• The FOR-22 dual 4-wire interface has been dropped.
Please familiarize yourself with the safety symbols in Figure 1. When
you see these symbols on a FOR-22 dual 4-wire interface, they warn
you of the potential danger of electric shock if the FOR-22 dual 4-wire
interface is used improperly . They also refer you to import ant operating
and maintenance instructions in the manual.

OPERATING THE
1
FOR-22 INTERFACE
This chapter describes how to use the FOR-22 dual 4-wire interface.
System operators can use this manual once the Eclipse System is
correctly installed and configured with the Eclipse Configuration
System (ECS) software, and after the FOR-22's internal jumpers are
set.
For information on configuring the FOR-22 interface, see the separate
manual for the Eclipse Configuration System.
DESCRIPTION
The FOR-22 dual 4-wire/radio unit forms an interface between an
Eclipse matrix and two external 4-wire devices, allowing the matrix and
the 4-wire devices to communicate with each other.
The external 4-wire devices that you can connect to the matrix with the
FOR-22 interface include camera intercoms, two-way radios,
microwave and satellite links, IFBs, and program audio.
Each of the two channels of the FOR-22 unit provides the following
functions for a port in the Eclipse System:
• Transformer isolation between an external 4-wire audio device or
system and the port.
• A set of relay contacts which are activated by a call signal from
the matrix.
• An LED indicator that lights when the relay is active.
• An optically isolated call signal input (from the external device to
the matrix).
• Separate "send" (to external device) and "receive" (from external
device) level controls on front panel.
• Send levels adjustable for line level, IFB feed level, and
microphone level (set by internal jumpers).
• A 2-color LED indicates correct signal level to external device.
The FOR-22 occupies one slot in an IMF-3 or IMF-102 interface
module frame or in an Eclipse Median frame. The two FOR-22
channels connect to the matrix frame via two 8-pin RJ-45 connectors,
and connect to external devices via two DB-9 9-pin connectors.

1-1
The installation chapter of this manual gives more information on
interface frames and on wiring the FOR-22 unit to the matrix and to
external devices.
OPERATION
In normal use, the FOR-22 interface does not require operator
interaction. Each channel features the same set of front panel
controls:
• A "send" level control
• A "receive" level control
• A "send level" LED
• A "relay active" LED
"SEND" CONTROLS
The "send" controls affect the level of t he signals from the matrix to the
external devices. This control should be adjusted so that the "send
level" LED (see below) lights green when a signal is present.
Occasional red flashes due to peaks in the audio signal are
acceptable. The "send" controls have a range of ± 10 dB.
"SEND LEVEL" LEDS
The 2-color "send level" LED lights green when the audio signal is
being sent to the external device at a typical acceptable level. The LED
lights red when the audio output signal level is too high.
"RECV" CONTROLS
The "recv" ("receive") level controls affect the level of the signals sent
from the external devices to the matrix. The "recv" controls have a
range of ± 10 dB.
RELAY ACTIVE LED
The amber "relay" LED lights whenever the relay is activated.

INSTALLING THE
2
FOR-22 INTERFACE
This chapter includes the following topics about installing the FOR-22
interface:
• Overview of interface frames and power supplies.
• Installing the interface in an interface frame.
• Wiring the interface to the matrix and to external devices.
• Adjusting the interface’s front-panel controls after installation.
INTERFACE FRAMES AND POWER SUPPLIES
Interface modules convert the 4-wire signals of a central matrix port to
some other form of communication, such as for telephones, camera
intercoms, two-way radios, and so on.
Each interface module connects to both the central matrix and to the
external device through cable attached to hardware connectors on the
rear of the interface module. To house these interface modules,
Clear-Com offers various types of interface frames. The two interface
frames which can house the FOR-22 dual 4-wire/radio interface are
the IMF-3 and the IMF-102 frames, which are described below.
IMF-3 Interface Module Frame
The IMF-3 interface frame holds up to 11 interface modules in three
rack units (3 RU) of a standard Electronics Industry Association
19-inch wide (48.26 cm) rack. The frame holds a modular,
rear-mounted connector panel for each interface, containing two RJ-45
connectors for connecting cable to matrix ports, and two DB-9
connectors for connecting cable to external devices. Figure 2-1
illustrates the rear panel of an IMF-3 interface frame, with 11
rear-panel assemblies installed.
The frame uses an external PSU-101 rack-mounted power supply to
supply power to the interface modules. A second PSU-101 can be
attached for redundancy.
As a rule-of-thumb, one PSU-101 power supply unit is required for
every two IMF-3 frames. A PSU-101 power supply unit requires 90 to
260 VAC at 45 to 65 Hz with a maximum dissipation of 80 watts. A
PSU-101 connected for redundancy requires very little current unless
used.
