Overview
Designed to deliver dependable remote fire monitoring and intuitive control, the Silent Knight SK-RZA4 Remote Annunciator by Honeywell brings enterprise-grade annunciation to your security and life-safety infrastructure. As an annunciator module for the SK-4 fire alarm control panel, the SK-RZA4 gives operators clear, at-a-glance status with separate red/yellow LEDs and zone-specific programming—helping teams act quickly during an incident. It supports four Style B initiating device circuits (IDCs) and two Style Y notification appliance circuits (NACs), with an optional SK-CAC4 module to convert all circuits to Class A for redundant protection. Synchronization for ANSI audible signals and ADA-compliant strobes ensures compliant, consistent notification across facilities, while selectable protocols for System Sensor, Wheelock, and Gentex simplify integration with existing notification appliances. Built-in features like manual horn silence (strobes continue), silent/audible walk tests, and alarm verification reduce nuisance alarms and streamline maintenance. Ideal for security integrators, facilities managers, and fire monitoring centers, the SK-RZA4 enhances surveillance, monitoring, and emergency response reliability. Order the SK-RZA4 to upgrade your fire annunciation and improve on-site safety and compliance.
