Information About EVS-100W
The EVS-100W is part of the Silent Knight Emergency Voice System (EVS) series by Honeywell, built to deliver high-performance audio amplification within life safety and fire communication systems. It provides up to eight supervised speaker circuits and includes its own power supply with battery backup for continuous operation during power loss. The amplifier can operate in several configurations, including 50W+50W backup or a single 100W channel, ensuring flexibility for system design. Fully supervised by the control panel, the EVS-100W maintains communication integrity and compliance with NFPA 72 and UL 864 standards for emergency voice signaling.
Key Features:
- High Output Power: Delivers up to 100 watts of audio power at 25 Vrms or 70.7 Vrms for clear message distribution.
- Flexible Configuration: Operates as 50W+50W backup, 100W single channel, or 100W with 50W backup (when used with EVS-100WBU).
- Integrated Power Supply: Includes a built-in power source with battery backup for continuous reliability.
- Eight Speaker Circuits: Provides eight supervised NAC outputs for multiple audio zones.
- Extended Mounting Distance: Can be installed up to 6,000 feet from the control panel for remote deployment.
- Compliant Design: Meets UL 864, UL 2572, and NFPA 72 low-frequency tone requirements for sleeping areas.
- Backup Amplifier Test: Allows physical testing of backup amplifier functionality for maintenance assurance.
- Wide Bandwidth: Supports 400 Hz to 4,000 Hz frequency range for high-quality audio transmission.
The EVS-100W delivers the reliability and precision required for emergency communication, life safety, and voice evacuation systems in commercial and institutional environments.
