Silent Knight EVS-100W Voice Evacuation Amplifier Module

Designed to deliver clear, reliable life-safety announcements across large facilities, the Silent Knight by Honeywell EVS-100W Voice Evacuation Amplifier Module ensures your fire voice evacuation system provides intelligible, code-compliant audio where it matters most. As a dedicated fire voice evacuation amplifier, the EVS-100W supplies up to 100 watts of audio power with an automatic 50W backup option to maintain operation during fault conditions. It is UL 864/2572 listed and supports low-frequency ANSI 520Hz speaker tones to meet NFPA 72 sleeping-area requirements, helping you meet regulatory and safety standards.

The EVS-100W integrates directly with Silent Knight 5820XL-EVS control panels, allowing up to four amplifiers and distribution over 32 audio circuits for zoned paging and evacuation. A built-in backup-amplifier test streamlines routine maintenance and verification, reducing inspection time and lowering lifecycle costs. With a 400–4000 Hz audio bandwidth, long-distance mounting up to 6,000 feet, and 120/240 VAC power options, it adapts to a wide range of fire, security and monitoring infrastructures.

Specify the EVS-100W to enhance your facility’s emergency communications and compliance — ideal for hospitals, campuses, industrial sites and critical security environments. Contact us to discuss system integration or to order.
