The WS-4 is a wall-mounted networked paging station that supports both standard and advanced public address functionality. Featuring embedded DSP, PoE, and on-board memory, all device-specific configuration information is stored locally, which means the WS-4 does not rely on a centralised controller for processing and page routing.
