Silent Knight ECS-CE4 4-Circuit Audio Expander

Increase audio coverage and zoning flexibility for your life-safety and emergency communication systems with the Silent Knight by Honeywell ECS-CE4 4-Circuit Audio Expander. Designed to pair directly with the ECS-125W amplifier, the ECS-CE4 adds four additional speaker circuits so a single ECS-125W (125-watts, with its own power supply and battery backup) can be expanded to support up to eight speaker circuits. That means broader site coverage, better speaker zoning, and improved message targeting for security, surveillance, and monitoring applications without costly amplifier replacements.

Built for professional alarm expansion, the ECS-CE4 streamlines deployment in schools, hospitals, industrial facilities and retail environments where reliable emergency audio and public address are critical. The expander integrates smoothly into existing Silent Knight ECS series systems, reducing installation time and simplifying ongoing maintenance. Enhance your emergency audio strategy and maintain compliance with safety protocols by adding focused speaker circuits where they’re needed most. Contact your Silent Knight distributor to add the ECS-CE4 to your ECS-125W setup and scale your emergency communication coverage today.
