2.1
Description
The Clear-Com ICS-22 is a two-channel speaker panel designed for use in theatres, live performances, industrial environments, and small television facilities. It features excellent speech intelligibility, even in high noise levels, and can be customized through its programmable options.
In addition, the ICS-22 contains a jack for an optional Clear-Com gooseneck panel microphone and a close-in, voice-operated circuit (VOX). This circuit allows automatic, alternate dipping of the panel microphone and the speaker in response to conversation.
Selectable talking and/or listening allows the operator to communicate on two talk/listen paths. The dual-action talk button operates in electronic momentary or latching mode. Monitoring can be done through the headset, the integral speaker, or both simultaneously. The ICS-22 offers both visible and audible call signaling to attract the attention of operators.
A balanced program input allows the monitoring of external audio using the headset or speaker. This program input can also be used as a paging function.
The ICS-22 speaker panel accepts dynamic headsets, such as the Clear-Com PL-
Pro™ Series HS -6 Telephone Handset, or PT-4 Push-to-Talk Hand Microphone. A sidetone control allows the operator to vary the level of his voice heard through the headset and speaker.
The integral speaker can be turned on or off by a convenient front-panel switch.
An automatic speaker dipping circuit will lower the level of the speaker whenever the talk button is activated. The
ICS22’s close -in VOX dips the speaker or gooseneck microphone automatically as the panel is used. These features help minimize acoustical feedback.
The ICS-22 will need to be powered locally. In permanent wall installations, a 16-
VAC doorbell transformer will provide a convenient source of power. In DT-Box installations, a 14- to 18-VAC wall-mounted transformer will suffice. The connections to this transformer are made to the circuit board’s two -terminal, plug-on connector.
The unit mounts either in a standard USA four-gang electrical outlet box or in an optional Clear-Com DT-Box. The extra thick front panel and compact, surfacemounted circuitry results in a reduced size and lighter weight package that maintains Clear-Com ruggedness.

ICS-22 Speaker Station | User Guide
2.2
Operation
Normal operation of the ICS-22 speaker panel only requires the front panel controls. For intercom operation, set the intercom level control to the desired level and press the talk button when talking. If a headset or handset is used, set the sidetone control for each channel for the desired amount of sidetone in the earphone. If the PT-4 hand-held, push-to-talk microphone is used, or if the panel microphone is used, set the sidetone controls for minimum feed-through to the speaker to prevent acoustic feedback.
2.3
EHX System Configuration for ICS-22 Panels
The Eclipse Configuration System (EHX) software does not directly support the
ICS-22 speaker panel. To configure an ICS-22 panel, the port is configured to drive an ICS-1008 panel with 14 keys (7 pairs of buttons). The two ICS-22 selectors are mapped onto the ICS-1008 keys starting from the left. Only the leftmost two pairs of keys on the ICS-1008 can be used to program the ICS-22; any other keys on the ICS-1008 will have no effect.
There must be a corresponding listen key on the top row to the talk key on the bottom row of the ICS-1008 configuration for the ICS-22 panel to work correctly.
If a talk key only is configured on the ICS-1008 in EHX the Talk key on the ICS-22 will not latch.
Note that the panel signalling and control protocol used by the Eclipse matrix differs from the Matrix Plus 3. So, the operation of these panels with an Eclipse matrix may be slightly different to their operation with a Matrix Plus 3.

2.4.1
Talk Button and Light
This button transmits the headset or gooseneck microphone audio to the selected talk/listen panel/interface or the answer-back label. The talk button has a dual action (momentary or latching) depending upon how the button is pressed. The
Talk button Latch/Non-Latching operation cannot be defeated in EHX even for latch disabled labels.
The following describes the various functions of this button:
Momentary — Press and hold the talk button while speaking. Release it when finished. The light will be illuminated when the button is pressed.
Latching — Press and release the button quickly to latch the talk function. Press and release the button again to turn off the talk function. The light will be illuminated while the button is latched.
Talk indication — The associated talk light will illuminate green when the talk function is activated.
Page 9
ICS-22 Speaker Station | User Guide
VOX indication — When the VOX feature is enabled, the talk light will illuminate green when the talk function is activated, but will turn red when the panel microphone is in use. This automatically dips the speaker volume.
Speaker dip — If the front-panel speaker is turned on and the VOX feature is not used, pressing the talk button will reduce the speaker output level to avoid feedback.
Note: The call-waiting light does not light when a call is received from a programmed label.
2.4.2
Answer-Back Facility
The answer-back facility answers calls from panels or interfaces that the panel has not currently selected.
Call-Waiting Light

is steadily lit when a call signal is received
flashes to indicate a call waiting signal, which has priority over a call signal.
Answer-Back Button
This three-function button:
sends a call signal to the selected, programmed label when the call waiting light is off
directs audio to the longest-waiting call in the call-waiting stack when the call waiting light is flashing
ends the current conversation from the call-waiting stack when the call waiting light is steadily on.
Answer-Back Stack
The answer-back stack tracks incoming calls from any label that is not assigned to the panel. These calls are available in the order they were received. The length of time the calls are available before they are automatically removed is set in the configuration program.
Note: The label programmed to and selected by the panel will never appear in the answer-back stack and duplicate labels are never added.
Answering a Call from the Answer-Back Stack
To answer a call from the answer-back stack:
Page 10
ICS-22 Speaker Station | User Guide

The receiving panel can terminate the call by pressing and releasing the answer-back button.
The calling panel can terminate the call.
Note: The configuration program can be set to also send an audible signal through the speaker, which can only be heard if the intercom level is turned up.
Note: Forcing the trimpots past their stop points will damage them.
Answering Another Call from the Answer-Back Stack
To answer another call from the answer-back stack:
If the calling panel disconnected the call, the call waiting light will flash.
If the receiving panel disconnected the call, a call from another unselected label will be activated when the answer-back button is released.
Sending a Call Signal
The answer-back button can send call signals to a panel or interface currently on the selected talk/listen path when the call-waiting light is not on. The light will turn on when the button is pressed and turn off when it is released.
Receiving a Call Signal
The call waiting light turns on when another panel sends a call signal and remains on during the call.
2.4.3

Caution:
Do not connect Pins 1 and 3 together. Headset extension cords or headset “Y” cables are not recommended because they may increase crosstalk between channels.
2.4.11
Panel-Mic connector
Clear-Com recommends that the GM-9 (9-in. long) and GM-18 (18-in. long) plugin panel microphones be used with the ICS-22. Both are the electret type. The
1/4-in. phone jack on the microphone mates with the panel-mic receptacle on the
ICS22’s front panel.
To install a GM-9 or GM-18 microphone there are four steps.
1) Remove the plastic plug from the jack, if present.
2) If a set screw is present in the microphone-mounting flange, check and unscrew it to make sure it is clear of the threads in the bushing.
Page 13
ICS-22 Speaker Station | User Guide
3) Screw the microphone into the bushing and tighten.
4) Optional: Replace the set screw supplied with the gooseneck microphone on top of the microphone-mounting flange and turn it clockwise to lock the microphone in place.
2.4.12
VOX Control
When the panel microphone is selected on the ICS-22, the VOX control should be adjusted for proper operation. This control is located to the right of the panel microphone connector and is recessed slightly into the front panel. Use a narrow, flatbladed screwdriver such as a “greenie” or “tweaker” for this adjustment.
When the adjustment is correctly set, the talk lamp will be red when speaking into the panel microphone and will be green when hearing audio from the speaker.
Turning the control clockwise makes the ICS-22 more sensitive. The VOX feature can be disabled by turning the VOX control fully counter clockwise.

This eight-wire modular jack (RJ-45) provides an audio and data communications link to the Matrix system.
2.5.4
Program-Input Connector (4)
A three-terminal, plug-on connector provides the program input to the panel.
Program is fed to the headset and speaker. The level to the speaker or headset is controlled by the program-level control. The program-input connector accepts a balanced or unbalanced line-level audio signal from -20 dBu to +10 dBu. If this input is connected to the stage announce (SA) output of a main panel it can be used as a paging input. Since the level of this input is independently adjustable from the intercom audio volume, it can be used to override the intercom audio.
Note: The Program Input can be set between -20 dBu to +10 dBu.

Power Connection (5)
The panel requires local power, which can come from various sources, including:
16-VAC Doorbell Transformer
A doorbell transformer can be attached to a separate box containing the powerline connection and the low-voltage, 16-VAC can be routed to the connector on the EB7-4W circuit board. This connection is especially useful if the headset or speaker panel is installed in a wall.
14-VAC Wall-Mounted Power Supply
A Clear-Com wall-mounted power supply (part number 400008) can be used for powering the panel from 120 VAC. (Use part number 400011 for 220 VAC power.)
This connection is a better choice if the headset or speaker is mounted in a desktop box, such as a Clear-Com DT-Box, which is not located on a wall.
24- to 28-VDC Source
The headset or speaker panel can be powered from a DC source, such as batteries.
To connect the selected power supply:
