Model DHF-102 Wall-Mount Hands-free Digital Intercom Station General Information This data sheet applies to the Model DHF-102 Flush-Mount Hands-free Digital Intercom Station, which is designed for use in hazardous and non-hazardous area communications, both indoors and outdoors, and in high noise areas. It is ideal for both large and small intercom systems. All communication to the station is via a two-wire digital communication line. The Model DHF-102 Wall-Mount Hands-free Intercom includes two programmable push buttons and a 16-button keypad. It also includes a built-in speaker amplifier and external audio output, and is available with an optional gooseneck microphone. This station provides all-call, group call, hands-free, and handset communication, input/output controls, and a variety of other functions. It also contains integrated functions such as door and gate control, and video integration, and control desk functions, etc. As a minimum, the Model DHF-102 requires a central cabinet to supply power for operation with its basic functions. A local 24 V ac or dc power source is required for full functionality (external speaker and audio line driver operation). Additional remote amplifiers can be installed with this station to broadcast audio into additional areas.
