Corbin Russwin ML20906 Lwa 626 Sec Lc Electrified Mortise Lock

Product Description

The CORBIN RUSSWIN ML20906 LWA 626 SEC LC is a field-reversible electrified mortise lock kit built on the ML2000 series platform, rated ANSI/BHMA Grade 1 for high-traffic and demanding commercial door applications. The lock operates in both fail safe and fail secure modes, drawing only 15 milliamps at 12 or 24 volts continuous, with a peak draw of 500 milliamps. The trim package includes a Lustra lever with an A Rose, finished in 626/US26D Satin Chrome. The lock case is heavy-gauge steel measuring 5.875 inches by 4 inches by 0.9375 inches. An ANSI Strike SS118 is included. The mortise cylinder is not included with this kit.

This kit is suited for commercial and institutional installations where electrified access control at a mortise lockset is required. Typical applications include office buildings, healthcare facilities, schools, and other high-traffic environments where the door must release or lock upon a loss of power, depending on the selected mode. The field-reversible handing allows the same unit to be installed on doors of either hand without disassembling the lock case, which reduces inventory requirements for contractors managing multi-door projects. Compatible door types include wood, hollow metal, and bullet-resistant doors at a standard thickness of 1.75 inches with a 2.75-inch backset.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with ANSI/BHMA mortise lock preparation standards. Disconnect all power to the access control system before wiring the electrified components. Verify door preparation depth and backset dimensions before installation, and confirm power supply capacity does not exceed two locks per 1-amp supply. Operating voltage must remain within plus or minus 10 percent of the rated 12 or 24 volts DC to ensure reliable electrified function.
