Description


VoiceCom 8 is an intercom system for two-way voice communication in industrial environments. It consists of central unit and up to 8 intercom units. Thanks to the robust, water-resistant metal construction, it is suitable for most harsh enviroment operating conditions. Voice proccesing and possibility of volume adjusting guarantees for audibility even in extreme surrounding noise situations. Modular design makes easy to extend system with new intercom units. Distributing of background music signal to all intercom units is enabled by appropriate audio connector.

 

Connections



Central unit uses powerline 220V AC. It can be connected with max 8 intercom units at distance up to 1.2km. Intercom system is connected into a star type configuration with two pair of wires. One wire pair is for half-duplex voice connection, while other pair is reserved for power supply, either from 220V powerline in case of local power supply, or 24V DC power supply from central unit. Pair of wires for power supply should be with greater cross-cut , and in case of resistivity greater than 2 Ω, local power supply should be used. If it’s necessary to connect more than 8 intercoms, more central units can be connected to one system.
