The E1-EX Series ECHO Intercom Stations provide safe and efficient two-way voice communications in ECHO Digital Intercom Systems.  This ECHO Station is designed and approved for use in Zone 1 and 2 Hazardous Areas including ATEX/IEC EX Zone 1, Gas Group IIB locations.

The E1-EX Series provides instantaneous high-speed connections and clear, crisp digital voice quality.  Each station offers single-button all call, priority emergency paging, group paging, speed dial, conference call, and relay output. 

Any station can call any other station(s) in an ECHO Digital Intercom System.  With the headset or gooseneck microphone options, each is capable of hands-free voice communication.  Because the ECHO Digital Central Exchange provides 30 channels of simultaneous communication, calls are processed and connected immediately without dial tone or delay. 

The keypad is designed to provide tactile and audible feedback (via external powered speaker) for positive activation.  Each station may be programmed for four levels of privacy for receiving calls;  non-private, semi-private, full privacy and do-not-disturb.  Volume for voice and signal levels are easily adjusted on the keypad. 

This station is constructed with a heavy duty, corrosion-resistant cast aluminum and a powder coated aluminum faceplate, equipped with weatherproof keypads, and is rated for use in Type 4X and IP66 dust- and water-tight applications.
