General Information
Product Overview
The GAI-Tronics Digital Intercom system is designed for use in
hazardous and non-hazardous area communications, both indoors
and outdoors, and in high noise areas.
The Model DSA-101 Remote Speaker Amplifier is designed
specifically to enable audio received by a DHX Series Intercom
Station to be broadcast into high noise areas.
System Requirements and Limitations
The DSA Series Remote Speaker Amplifier requires a 24 V ac or
dc power source to operate. A DHX Intercom Station with an
audio line output is required as the audio source.
Audio received by the DHX Intercom Station is automatically
transmitted to the remote speaker amplifier, except when the
intercom station’s handset is off-hook. A maximum of six remote
speaker amplifiers can be connected to a single Intercom Station.
Features and Functions
• 24 V ac or dc power • Power indicator
• Enclosure rated Type 4X
• 12-watt speaker amplifier
• Volume control
Fault indicator

This station contains a high gain amplifier that enables operation in high noise environments. To prevent
feedback problems in the system, the ambient noise levels, volume settings, and station placement must be
taken into consideration. This minimum spacing requirement between stations can be reduced under the
following conditions:
• Pointing the speaker as away from Intercom Stations
• Placing the speaker in separate rooms from Intercom Stations
• Reducing volume levels
