Telex 4015-100 25-Pair Cable Assembly

The 4015-100 is a factory-terminated 100-foot 25-pair cable assembly for RTS and Telex wired intercom systems, part of the 4000 Series IFB and two-wire family. It carries the multiple audio-and-power pairs a partyline needs down one bundled run, so an installer pulls a single tidy cable between racks, junctions, and station drops instead of lacing up two dozen individual lines by hand.

Because the pairs are already grouped and terminated at the factory, the 4015-100 saves shop time and keeps a two-wire install consistent from job to job. Choose the length that matches the throw between your power supply and station field; this is the 100-foot version, and the 50-foot 4015-50 covers shorter runs.
