Lifesafety Power RGM75B-D8PZ 4 Door 75W Integrated Mercury Drawer
Overview
The RGM75B-D8PZ is a 75W integrated Mercury drawer designed for multi-door access control installations where centralized power distribution and relay control are required. This unit consolidates four-door power management and Mercury protocol signaling into a single enclosure, eliminating the need for distributed relay boards across your facility. Deploy this where you need to manage door strikes, mag locks, and request-to-exit devices from a single point — typical in small commercial buildings, office suites, or secure entry lobbies handling four independent access zones.
Compatibility
This drawer works with Mercury-protocol access control systems and requires integration with a compatible access control panel or gateway that outputs Mercury commands. Four-door capacity means each of the four relay outputs can independently control a door strike, electromagnetic lock, or exit device. Verify your panel supports Mercury protocol before ordering — Mercury is distinct from Wiegand or RS-485, so confirm your system architecture beforehand.
Installation Notes
Standard four-post mounting means this unit mounts into a 19-inch relay rack or wallmount bracket assembly. Single or dual voltage operation (selectable at install) accommodates both 12VDC and 24VDC installations — confirm your facility's power standard before commissioning. UL/CUL/CE certification verifies electrical safety compliance for commercial access control environments. Wire the four Mercury inputs to your access panel outputs using shielded twisted-pair to minimize noise — long cable runs (over 100 feet) may require line termination. Each output terminal handles typical strike/lock current; verify your specific device current draw against the 75W total budget to avoid undersizing for simultaneous door activation.
