Schlage L9092EUL 03B 626 Electric Mortise Lock

Product Description

The SCHLAGE L9092EUL 03B 626 is a Grade 1 fail secure electric mortise lock designed for commercial access control applications. In a fail secure configuration, the lock remains locked when power is removed, maintaining door security during a power outage. This unit ships less cylinder, meaning the lock cylinder must be sourced and installed separately. The satin chromium plated finish (626) provides corrosion resistance suited to high-traffic commercial doors. It is field reversible, allowing installation on doors with either hand without special hardware. Licensed locksmiths, security installers, and commercial door hardware specialists typically perform installation.

This electric mortise lock is intended for commercial interior or exterior doors where access control integration is required. The 03 lever and B rose configuration define the trim style and fit standard commercial mortise door preps. Fail secure operation makes this lock appropriate for server rooms, secured storage areas, and other spaces where the door must remain locked during a power interruption. The field reversible design reduces inventory requirements for contractors working across mixed-hand door schedules.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with access control wiring. Disconnect and lock out all power to the access control system before wiring the electric mortise function. Verify door hand orientation before installation; although the lock is field reversible, confirm the door prep dimensions match the mortise body before cutting. Work must comply with applicable local building codes and NFPA 80 requirements for fire-rated door assemblies where applicable.
