i an I. The Clear-Com Concept Clear-Com is a closed-circuit intercom system that provides highly intelligible, two-way communications ability in high- and low-noise environments. A basic system consists of a Power Supply or Main Station connected to various Remote Headset or Speaker Stations. Clear-Com manufactures a wide range of portable, rackmount, and custommount intercom stations. All are compatible and will interface with a variety of other communications systems.
=I. Introduction to the PS-10 Power Supply, continued tically re-sets the system. The PS-10 front panel provides an XLR-type, 3-pin male connector for convenient output to an intercom at INTERFACING WITH OTHER SYSTEMS The Clear-Com AC-1O "Adapt-A-Com" is a universal adapter that interfaces the Clear-Com intercom system with another intercom or communications link/device. The AC-10 guarantees compatibility with virtually any in-house intercom you may already have, be it a 2-, 3-, or 4-wire system.

7 I m SYSTEM INTERCONNECTION The PS-1OK mounts in a standard 19" rack, while the portable PS-10 can go anywhere. Cable is run from the 3-pin connectors to all headset and speaker stations. Allow at least three inches behind the unit for cables extending from the rear panel, and avoid sharp bends in the cabling. The PS-10 provides four XLR-type 3pin connectors for intercom output. All four are internally connected in parallel.
III System Interconnection, continued together. The chassis is insulated from the signal ground with a capacitor (.01 microfarad, 1.4 kv). This eliminates the hum and potential shock hazard that can arise if intercom stations are at a different ground potential- If the conduit already has Class II wiring, you can use that, it's shielded or not.
System Interconnection, continued MULTIPLE POWER SOURCES Power Supplies and Main Stations can be paralleled together in the intercom system. A second power source doubles the system capacity and acts as a back-up if the other source goes down. The diagram below illustrates interconnection of two power the sup- plies, which may be installed at the same end of the intercom line or at opposite ends.
U.g TROUBLE-SHOOTING THE PS-IO SYMPTOM CAUSE REMEDY System is totally dead, light in power switch doesn't come on a. loss of AC power a. plug the power supply into a good outlet b. replace fuse* b. internal fuse has blown Circuit breaker trips repeatedly, or "short" LED remains lit a. shorted or mis-wired interconnect cable b. defective remote station remove cables from the power supply, one at a time, until the faulty line is isolated.
.V WARRANTY AND MAINTENANCE Your Clear-Com System contains modular, solid-state equipment that allows system expansion and field serviceability. Efficient ventilation is inherent in chassis design; the PS-dO can withstand an ambient temperature of 50 degrees C (122 packaging F). Rugged degrees guards against abuse; the chassis are 16 gauge aluminum or stainless with double-sided, glass steel, Our conepoxy plug-in PC boards. circuitry servatively-engineered assures the longest component life.
