INSTALLATION / Clear-Com CS-222 2-Channel Main Station * 2.3 REAR PANEL DESCRIPTION CIL SS CS-222 Rear Panel 1. Power Swltch The AC "Power Switch" is located on the top left corner of the rear panel. The switch is a rocker switch with a "1"n mark for on and "0" for off. i 2. Power Connector Just below the power switch is an EIA power receptacle for either 115 or 230 VAC ~~~power input. w ~~3. Power Voltage Select and Fuse Block Just below the EIA receptacle is a plug-in fuse block. By placing a flat blade screwdriver in the slot between the connector and the block and twisting slightly the fuse block will release from the connector. Complete removal of the block will give access to both fuses. Both fuses are identical in value regardless of the AC voltage applied. By turning the block over when replacing it in the receptacle will convert the input voltage range. lii yvllgta range that ini sad rigflt aid e u n Ibottomni of a bflc in Ibnt winf selected 4. Intercom Line Connectors There are two sets Of three XLR-SM intercom connectors for both channel outputs. Standard Clear-Corn wiring is as follows: Pin 1 -- Ground Pin 2-- +30 VDC Pin 3 - intercom Audio 5. Termination Switches Each intercom channel is provided with a 'Termination" switch allowing easy termination of the intercom line. The switch is provided in case there are multiple MAIN stations connected to the inter-corn line. CAUTION: FOR PROPER OPERATION IT IS IMPERATIVE THAT QMJAND OLY 0 DUE TERMINATION BE PRESENT ON A CLEAR-COM INTERCOM LINE. CLEAR- COM LINE DRIVERS DEPEND ON A KNOWN LOAD VALUE FOR PROPER OPERATION. 11/90 Rev. 1.0 Page 12
INSTALLATION / Clear-Corn CS-222 2-Channel Main Station 6. Announce Output Connector The "Announce" output is a XLR-3M. The output is transformer isolated, 600 ohms output impedance, and has an output level of approximately 0 dBv. Wiring is as follows: Pin 1 -- Ground Pin 2 --- Audio Pin 3 -- +Audio 7. Announce Relay Contact Terminals The "Announce" relay contacts are available on a screw terminal block. The relay contacts are "Form C" (break before make). The contact description is as follows: Left most ---- N/O --- Normally Open Contact Center ------- C --- Wiper Right most -- N/C --- Normally Closed Contact 8. Program Input Connector The "Program" input is a XLR-3F. It is an electronically balanced (differential) input. Wiring is as follows: Pin 1 -- Ground Pin 2-- -Audio Pin 3 - +Audio 9. Program Gain Switch The "Program Input Gain Switch" is located next to the "Program Input" connector. In the "Mic" position the input will accept a 'low' impedance dynamic microphone and produce a usable level from a -65 dBv input signal for monitor and intercom line feed uses. In the "Line" position the input presents a balanced high impedance and a -15 dBv input signal will produce a nominal intercom level on an intercom line. 11/90 Rev. 1.0 Page 13
