The EWS-4 is a wall-mounted networked paging station for use in Vocia systems. The EWS-4 features embedded DSP and on-board memory to support standard and advanced public address and mass notification functionalities. The EWS-4 can store four user-configurable page codes. Additionally, all device-specific configuration information is stored locally, which means the EWS-4 does not rely on a centralized controller for processing and page routing. Thus, the processing, routing and storage functionality in a Vocia system is decentralized, which eliminates any centralized point of failure. As part of the Vocia system, the EWS-4 meets EN 54-16 certification for facilities of all sizes.
