Schlage L283-347-EL Electrically Locked (Fail Safe) Lock Case, For Use With L9090/92/94 Series Mortise Lock, Field Reversible

The Schlage L283-347-EL is an electrically locked (fail safe) lock case engineered for use with L9090, L9092, and L9094 Series mortise locks. In a fail safe configuration, the lock releases and allows free egress when power is lost, making it ideal for openings where life safety and code compliance are priorities. This component is field reversible, so a single unit adapts to either handing during installation without additional parts. Built to Schlage's commercial-grade standards, it integrates cleanly with existing L Series mortise hardware and supports electrified access control applications in institutional, healthcare, and commercial facilities.

Features

• Electrically locked (fail safe) operation releases the lock when power is removed for free egress.
• Designed specifically for use with Schlage L9090, L9092, and L9094 Series mortise locks.
• Field reversible design accommodates either door handing on site.
• Replacement lock case that restores or converts existing L Series mortise hardware to electrified function.
• Commercial grade construction suited to high-use openings.

Functional Details

In a fail safe (electrically locked) arrangement, the lock case is held secure while energized and unlocks automatically upon loss of power, permitting immediate egress. This behavior supports emergency and life-safety requirements where doors must free up during a power interruption.
