DW-IP2 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.
