SKE-450 SILENT KNIGHT

Product Overview

The Silent Knight SKE-450 is a 50-watt voice evacuation system designed to deliver clear, reliable emergency audio messaging with maximum flexibility for a wide range of installations. When one of its two alarm inputs is activated, either reverse polarity or supervised dry contact, the system automatically broadcasts a pre-recorded digital voice message corresponding to the triggered input.

The SKE-450 features a built-in Digital Message Repeater, supervised microphone, power supply, and Digital Signal Processor (DSP), all housed in a secure dead-front cabinet that protects users and prevents tampering. Audio messages are fully programmable and can be recorded directly through the microphone, via line-level input, or downloaded as needed, making the system ideal for both new installations and retrofit projects.
