Clear-Com TW47

 Compatible with both Clear-Com and RTS®, this versatile interface connects virtually any walkie-talkie to the party-line intercom, using one walkie-talkie as a base station. A person on a remote walkie-talkie can then converse seamlessly with anyone on the wired intercom system. The base-station radio is keyed from the intercom call signal. Extensive RF and EMI isolation prevents interference from entering the intercom system. Separate transmit and receive level controls are provided, along with audio level and transmitter keying indicators. The stand-alone interface is powered by the intercom line.
