SKE-450ZN4 SILENT KNIGHT
Product Overview
The Silent Knight SKE-450ZN4 is a 50-watt voice evacuation system designed to deliver clear and controlled emergency audio messaging across four independent speaker zones. When one of its alarm inputs is activated, the system automatically plays a corresponding pre-recorded digital voice message, ensuring effective communication during emergency situations.
The integrated 4-zone splitter (ZN4) divides the amplifier output into four Class A or Class B speaker circuits, allowing paging by individual zone or through an All Call function that activates all zones simultaneously. With built-in digital message repeating, supervised microphone, power supply, and system status indicators, the SKE-450ZN4 provides a reliable and flexible solution for life safety voice evacuation applications.
