Secutron MRI-4003-R Relay Base

Ensure dependable control and simplified integration for fire and security systems with the Secutron MRI-4003-R Relay Base. This detector base provides a single Form C (SPDT) relay—rated at 2A at 30Vdc (0.5A at 125Vac)—so compatible control panels can switch discrete contacts to manage alarms, annunciators or auxiliary devices without complex rewiring. Built to accept both isolated and non-isolated detectors, the MRI-4003-R adapts to diverse installations and reduces field labor for retrofit and new-construction projects. Engineered to meet UL268/ULC S529 requirements for smoke detectors and UL521/ULC S530 for heat detectors, the Secutron detector base supports code-compliant fire detection while enabling seamless integration with security, surveillance and building monitoring platforms. Ideal for commercial buildings, data centers and critical infrastructure where dependable event signaling and remote control matter most. Add the MRI-4003-R Relay Base to your specification to enhance monitoring reliability and streamline system upkeep—contact your sales representative or order online for fast deployment.
