The TW-47 is a stand-alone interface designed to connect a 2-way radio or walkie-talkie into a single channel of a standard Clear-Com, RTS* (*for RTS systems equipped with the Call Light feature), or compatible 2-wire party-line intercom system. It provides both 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 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.

In order 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 -57dB microphone level to +11dB line level are supported. A bi-color LED provides a visual indication of audio level from the intercom line.

A relay contact provides the required "Push-to-Talk" transmitter "keying" of the radio. This relay is activated by detecting the "Call Signal" on the intercom channel. The relay contacts, in conjunction with the custom-made radio cable, allow correct transmitter keying of virtually any type of radio. A "Transmit Key" LED indicates that the relay is active.

Certain Clear-Com stations can be set up so that the Call signal is activated automatically when the Talk button is pressed (Talk-on-Call). With these stations, the radio transmitter can be keyed by simply pushing the Talk button. The operation of the 2-way radio then becomes seamless and transparent to station users.
