Zenitel Turbine Ex | Industrial Intercom use

When used with Zenitel Turbine Ex or Industrial Intercom stations, the headset must be connected via the TAX-2B or TA-22B cable with plugbox. This cable assembly provides the required interface between the headset and the intercom station. In this configuration, the AK5850B supports HD Voice functionality with compatible Zenitel intercom systems.

Used together with the TAX-2B or TA-22B cable and plugbox with PTT, the solution provides reliable communication with an operating range of over 10 meters, depending on installation and operating conditions.
