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 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 paging requirements for facilities of all sizes.
