Secutron MRI-4045 Dual Relay Module

The Secutron MRI-4045 Dual Relay Module delivers reliable, address-efficient control for fire and security systems by providing two independent, supervised outputs while consuming only one module address. Ideal for integrating external devices—such as door holders, HVAC shutdowns, annunciators or auxiliary notification—the MRI-4045 uses two Form C (SPDT) contacts rated at 2A at 30VDC or 0.5A at 125VAC and verifies contact position continuously to reduce false indications and simplify monitoring.

Designed for use with compatible fire alarm control units on a single Signaling Line Circuit (SLC), the MRI-4045 supports group activation for fast coordinated responses and mounts easily in a standard 4" square or double-gang back box for straightforward installation. A panel-controlled LED provides clear local status, and contact troubles are reported automatically for rapid maintenance. With industry-grade supervision and compact form factor, this relay module streamlines integration into security, surveillance and building monitoring systems.
