DW-IP2 Digital weatherproof call station

DW-IP2 weatherproof loud-speaking call station is used at industrial and transportation sites in distributed and centralized Intercom and PA/GA communication system Armtelics.

DW-IP2 is designed for outdoor use and harsh environments with high humidity, noise, dust and smoke levels including environments with aggressive chemical vapors, within the broad temperature range. DW-IP2 includes built-in software and configuration data for direct communication with other subscribers of the communication system, processing of calls priority, control of communication and indication modes.

  • Wide range of optional modules;
  • Group simplex calls;
  • Duplex and half-duplex communication via SIP protocol;
  • Use of toggle switches / pushbuttons and dial pad for communication;
  • Two ways of connection: Ethernet port or ADSL port via twisted pair cable
  • Communication via SIP or Armtel-IP protocols;
  • Volume control of integrated loudspeaker and a handset speaker;
  • One-way control mode and «End call» function;
  • Recording and playback of voice messages;
  • Indication of faults on call pushbuttons of associated device;
  • Control of external signalimg device with the help of built-in relay.
