Handset Digital Intercom Station

General Information

This data sheet applies to the Model DHS-101 Wall-Mount Digital Intercom Station (NEC Div. 2), 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 DHS-101 Wall-Mount Digital Intercom includes a handset 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 DHS-101 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.
