INTERCONNECTION to a HARD-WIRED INTERCOM SYSTEM

The RADIOCOM wireless system can be integrated into Telex intercom systems and most existing wired intercom systems includ- ing RTS and Clearcom.

Connect the intercom cable to the back of the BTR-300. There are two intercom connections on the back of the unit, one being a male con- nector, the other a female connector, con- nected in parallel with each other. Either works as an input or output.
