Silent Knight ECS-CE4 (4-Circuit Audio Expander)

The Silent Knight ECS-CE4 is a four-circuit audio expander for ECS-Series emergency communication systems. It installs inside an ECS-50W or ECS-125W amplifier cabinet and adds four supervised speaker circuits for distributed paging and emergency tones. Circuits are mapped through the host ECS system for group selection and All Call or Non-Active Call operation. The compact, in-cabinet design keeps wiring short and fully supervised.
