Dukane Intercom Phone


The Edwards Model 9A1875B Remote Intercom Amplifier acts as an interface between communications systems and intercom speakers. The 9A1875B can be located up to 300 feet (91.4 m) from its host systems as required by facility and communications system design. Greater separations are possible by using preamplifiers in the lines between the 9A1875B and the voice input components. The 9A1875B accepts microphone, speaker, push-to-talk, and carbon handset intercom inputs from most communications systems, and provides auxiliary line level outputs to page amplifiers.The 9A1875B operates in half-duplex mode when connected to remote intercom stations, with the system operator controlling audio direction. Audio direction is controlled by a push-to-talk switch or, if a carbon handset is used, the remote amplifier’s built-in voice operated switching (VOX) circuitry. Contacts are provided to allow handset VOX override in noisy environments. The 9A1875B provides full-duplex operation during master station-to-master station communication through handsets.
