Vocia EWS-4 Vocia Emergency Wall-Mounted Paging Station

Emergency Wall-Mounted Paging Station for Critical Communication
The Vocia EWS-4 is a networked emergency paging station designed for use in EN 54-16 certified life safety systems. Equipped with four user-configurable buttons and a high-quality noise-canceling handheld microphone, this unit ensures fast and efficient communication during emergencies. With embedded digital signal processing (DSP), onboard memory, and Power over Ethernet (PoE) capability, the EWS-4 provides a reliable and independent paging solution without relying on a centralized controller.

Configurable Page Codes and Emergency Priority Levels for Critical Messaging
Supporting four user-configurable page codes and up to 250 software-configurable priority levels, the EWS-4 ensures that emergency messages are delivered with the appropriate urgency. The device also features four emergency priority paging levels, allowing high-priority messages to take precedence in critical situations. This makes it ideal for hospitals, transportation centers, and large public facilities where emergency paging is essential.

Built-In Digital Signal Processing for Clear and Reliable Audio
The EWS-4 integrates local DSP, providing gain control, filters, and a compressor/limiter to optimize speech intelligibility in any environment. Local storage of default and custom preambles ensures that pre-recorded messages can be included in announcements. Additionally, the built-in store-and-forward functionality guarantees that pages are retained and played back even in the event of temporary network disruptions.

Seamless Network Integration with CobraNet and Power over Ethernet
Designed for modern AV and life safety systems, the EWS-4 supports CobraNet for dynamic audio routing and system control. Power over Ethernet (PoE) eliminates the need for additional cabling by delivering both power and data through a single connection. An auxiliary port allows the use of an external 24V power supply for redundancy, ensuring continuous operation even during power failures.

Enhanced Security with PIN Protection and LCD Display for User Control
To prevent unauthorized use, the EWS-4 features an optional PIN-based access restriction, ensuring that only authorized personnel can initiate emergency announcements. The backlit LCD display provides real-time system information, making it easy to monitor status updates and paging activity, even in low-light conditions.

Durable Surface-Mounted Housing for Long-Term Reliability
Built for demanding environments, the EWS-4 features a sturdy, surface-mountable component housing designed for long-term use. Rotary ID switches allow for easy unit identification and system integration, simplifying setup and configuration. Whether installed in office buildings, government facilities, or industrial complexes, this paging station is built to withstand rigorous use.

TAA Compliance and Certification for Government and Enterprise Use
The EWS-4 meets U.S. Trade Agreement Act (TAA) compliance requirements, making it eligible for federal procurement and government contracts. It is EN 54-16 certified, EN 60849 & AS 60849 verified, CE marked, and RoHS compliant, ensuring adherence to stringent industry safety and environmental regulations. This makes it an ideal choice for any professional emergency paging or life safety system.
