General Information
Product Overview
The GAI-Tronics DHS/DHF Series Digital Intercom
Stations are designed for use in hazardous and non-
hazardous area communications, both indoors and
outdoors, and in high noise areas.
The DHS/DHF Series Intercom Stations are ideal for
both large and small intercom systems. Communication
and security systems can be networked to include up to
120 intercom servers with the capability to support a
corresponding maximum of 5,760 stations. The
systems can be upgraded to include alarms, radio
interface, telephone interface, music, etc. All
communication to the stations is via a two-wire digital
communication line.
These intercom stations provide all-call, group call,
hands-free, handset and headset communication,
input/output controls, and a variety of other functions.
These stations also contain integrated functions such as
door and gate control, and video integration, and control
desk functions, etc.
System Requirements and Limitations
As a minimum, the DHS/DHF Series Stations require 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,
audio line driver and headset operation). Remote amplifiers can be installed with these stations to
broadcast additional audio.
