Description


VoiceComDX (VCDX) is an intercom system inteded for two way voice communication in industrial environments. System consists of central unit and intercom units, but there are some optional devices such as backup power supplies or external loudspeakers. Thanks to the robust, water and dust resistant metal construction, it is suitable for most harsh enviroment operating conditions. Basic system consisted of 8 intercom units, can be extended up to 64 intercom units by connecting several central units. Voice proccesing and possibility of volume adjusting guarantees for audibility even in extreme surrounding noise situations. Intercom unit has metal bar for switching between speak and listen.

 

Connections



Intercom system VCDX has all standard phone line functions, such as dialing, establishing and disconnecting call, with DTMF signalisation. Beside that, it has capability of forming group call, conference call and priority call. Special configuration is dispatcher system where one of intercoms is dispatcher unit. In this configuration intercom units can make a call only with dispatcher. Intercom units which are not invited in to conversation can not listen the call between dispatcher and other intercom unit. Dispatcher unit has LED indication of intercom units status. It can establish and disconnect call with intercom units, and to invite them to conference call.
