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.
