DSC RM-2 End-Of-Line Power Supervision Relay for 4-Wire Smoke Detectors

Keep your fire alarm network reliably supervised with the DSC RM-2 end-of-line power supervision relay. Designed specifically for 4-wire smoke detectors, this DSC relay delivers continuous monitoring of detector power integrity so security and facilities teams can quickly identify wiring or power faults before they become system failures. With a minimum operating voltage of 10V DC and hybrid installation flexibility, the RM-2 integrates smoothly into DSC/Johnson Controls panels and existing fire and security architectures, minimizing installation time and service disruption. By providing dedicated end-of-line supervision, the relay helps reduce false alarms and ensures compliant supervisory reporting for commercial and industrial installations. Ideal for use in security, surveillance, and building monitoring environments, the RM-2 strengthens your fire detection layer and supports uninterrupted operation of critical life-safety systems. Improve your system reliability and simplify maintenance — add the DSC RM-2 relay to your fire alarm supervision strategy today.
