Schlage L283-392 Eu Fail Secure Electric Lock Case Rtx

Product Description

The SCHLAGE L283-392 EU is a fail secure electric lock case designed for controlled egress applications in commercial door hardware systems. Operating on an electrically unlocked principle, the lock case remains locked during a power loss and releases only when energized, making it appropriate for secure access points where latch retraction must be intentional. A built-in request-to-exit function supports integration with access control panels and egress detection systems. The lock case is field reversible, allowing installation teams to configure handing on site without returning the unit or ordering handed components. Licensed locksmiths, door hardware specialists, and commercial security integrators are the primary installers.

This lock case is intended for commercial interior and exterior door applications where controlled access and monitored egress are required. It is engineered for use with SCHLAGE L9090 and L9092 series mortise locks. Typical install scenarios include office corridors, stairwells, and controlled-access suites where access control systems must verify exit events. The field-reversible design reduces job-site inventory requirements when servicing multiple door configurations in a single building.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with commercial mortise lock systems and applicable access control wiring practices. Disconnect power to the access control system and any electrified hardware before beginning work. Verify door prep dimensions and backset against the existing mortise pocket before installation. Field reversibility should be completed before mounting the lock case in the door to avoid damage to internal components.
