The ClearCom TW-47 is a stand-alone intercom system interface designed to connect any 2-way radio or walkie-talkie into a single channel of a standard Clear-Com, RTS Systems with call light, or compatible 2-wire party-line intercom system. It provides both an audio connection and "push-to-talk" transmitter keying, using standard Call signals.
The ability of a 1- to 5- watt walkie-talkie to both talk to and receive from the wired intercom system can greatly extend an intercom system's capability, especially in very large indoor and outdoor facilities and venues. The TW-47 is powered directly from the intercom line, and connection to the radio is via a single DB-9F 9-pin connector. The interface has extensive RF and EMI isolation to prevent the 2-way radio RF from radiating into the intercom system.
To accommodate the widest variety of 2-way radios, the TW-47 is supplied with a 9-pin connector and wiring diagrams for many 2-way radios. The combination of internal jumpers (switches) and front panel "Transmit" and "Receive" level controls assures correct level matching to virtually any radio. Adjustments from -57 dB microphone level to +11 dB line level are supported. A bi-color LED provides a visual indication of audio level from the intercom line.
