Schlage L9092EUP 03A 626 Fail Secure Electric Mortise Lock

Product Description

The SCHLAGE L9092EUP 03A 626 is a Grade 1 fail secure electric mortise lock designed for commercial door hardware applications. In a fail secure configuration, the lock remains locked when power is lost, making it appropriate for controlled-access openings where security must be maintained during outages. The unit features a conventional cylinder, a 03 lever handle, an A rose trim, and a satin chromium plated (626) finish. It is field reversible, allowing installation on doors with either hand without special-ordering a separate unit. Licensed locksmiths, commercial door hardware installers, and security system integrators are the primary trades that install and commission this hardware.

This electric mortise lock is intended for commercial and institutional applications where access control integration is required. Typical installations include office entry doors, stairwell doors, server room entries, and other controlled-access openings that require electrified hardware tied to an access control panel or credential reader. The field-reversible design reduces the need to stock multiple handed units, and the Grade 1 rating confirms suitability for heavy-use commercial door openings.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with electrified hardware and access control wiring. Disconnect power to the access control panel and de-energize the door circuit before servicing or installing the lock. Follow local building codes and AHJ requirements for electrified hardware on egress and fire-rated doors, as fail secure locks on certain egress paths may require additional compliance review. Confirm door hand and backset before mounting to take full advantage of the field-reversible feature.
