Secutron MRI-4050 Sync Module for MGC Notification Devices

Deliver reliable, code-compliant notification across your facility with the Secutron MRI-4050 Sync Module for Control Panel Modules. Designed for MGC notification appliance circuits (NACs), this hardware-only sync module aligns strobe flash patterns with audio signals and supports two-stage alert/evac sequencing — all without programming. The MRI-4050 synchronizes up to 20 interconnected modules and can manage one Class A or two Class B NAC lines, ensuring uniform notification in large commercial, institutional, or industrial fire alarm systems. Installers benefit from a fail-safe relay that supplies NAC power by default, an isolated silence input to locally mute horns while maintaining strobe operation, and simple mounting in a standard 4” square or double-gang back box. With no standby power draw and a built-in LED that indicates master/slave status, the module reduces commissioning time and ongoing maintenance costs. Ideal for integrators focused on security, surveillance, and life-safety monitoring, the Secutron MRI-4050 provides dependable synchronization for notification appliances. Contact your distributor or specify the MRI-4050 for your next fire alarm or security monitoring project.
