Intercom A8ex is applied in potentially explosive gas environment, except mines and their land structures dangerous on firedamp where under the terms of operation the GGS usual equipment is inapplicable.
The case of intercom A8ex dielectric is also manufactured of steklonapolnenny material. Material and a design of the case provide crash-worthiness and chemical stability.

As a part of digital system of a conference circuit by means of A8 of Ekh implementation of the following functions is possible:

  • communication of subscribers by means of the receiver;
  • connection of the additional amplifier and external loudspeaker;
  • connection of the portable microphone;
  • indication of a call, condition of the line, storing of a call by means of the light-emitting diodes established under each button;
