General Information
Product Overview
The GAI-Tronics DHS/DHF 200 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 200 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 control desk functions.
System Requirements and Limitations
As a minimum, the DHS/DHF 200 Series Stations require a system central to supply power for operation
for 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. Refer to Pub. 42004-452, “Model DSA-201 Remote Speaker Amplifier.”
