Multi-voltage relay modules provide the electrical interface between a fire alarm control panel and auxiliary building systems that the alarm needs to actuate — elevator recall per ASME A17.1 / NFPA 72 firefighter recall, HVAC fan and damper shutdown, magnetic door holder release, and similar control functions. The MR-Series accepts either AC or DC coil voltage from the panel or NAC, and provides multiple isolated dry-contact outputs for downstream control wiring. The clear-cover variant allows the installer to verify relay state visually during commissioning and troubleshooting without removing the enclosure.

Verify panel/device family compatibility before ordering.
