Introduction

General Description

The Telex Radiocom BTR-500 and BTR-600C UHF Wireless intercom systems offer the ultimate in reliable, high performance, high fidelity full du- plex communications.

The BTR-500 series includes the BTR-500 fre- quency agile base station, working with the TR-500 transceiver beltpack. The BTR-500 base station pro- vides full duplex communications with a single beltpack. Sixteen BTR-500s, or more, may be oper- ated simultaneously. Also a single BTR-500 base station can accommodate an unlimited number of beltpacks operating in “Push-to-Transmit” mode.

The BTR-600C series has all the features of the BTR-500 with the addition of digital modulation and encryption for secure communications. Base station and beltpacks can choose from over 65,000 user selectable security codes out of over 16 million possible codes by means of four cipher code switches on the units. Sixteen BTR-600C, or more, may be operated simultaneously, permitting 16, or more, discrete full duplex radio channels.

The BTR systems incorporate auto-switching 2 channel operation, permitting the beltpack operator to choose between 2 separate audio channels of communications, with the base station tracking the beltpack selection. Auto-switching allows the user the flexibility to create a party-line and a private line within the same beltpack.

The BTR-500 and BTR-600C systems are perfectly suited for stand-alone operation and also can inter- face with Audiocom® (Telex), RTS® TW, as well as RTS Matrix systems and other 4 wire communi- cations systems. Clear-Com®intercom system may also be interfaced to a BTR-500 and BTR-600C systems through the use of a Telex to Clear-Com In- terface box, see “Accesories” for more information. In addition to the external intercom systems inter- faces listed above, the base stations provide connec- tions for auxiliary balanced audio input and output.

The Radiocom BTR series has been designed for re- liable, efficient operation. Operating in the 520 to 760 MHz range, the units operate reliable at dis- tances of 1,000 feet. With available antenna systems from Telex, the effective operating range can be ex- tended. The high efficiency beltpacks provide 12 hours of uninterrupted operation using standard al- kaline batteries.
