Schlage L283-347 El Fail Safe Lock Case Field Reversible

Product Description

The SCHLAGE L283-347 EL is a fail safe electrically locked lock case designed for commercial door hardware applications. In a fail safe configuration, the lock releases when power is interrupted, allowing free egress during a power outage or emergency. This lock case is field reversible, meaning the handing can be changed on-site without special tooling or returning the unit to the factory. It is typically installed by licensed locksmiths or commercial door hardware technicians as part of a complete mortise lock assembly.

This lock case is compatible with the L9090, L9092, and L9094 series mortise locksets. It is suited for commercial and institutional interior doors where access control integration and life-safety code compliance are required. Typical applications include office corridors, institutional facilities, and secured entry points where electric access control systems are in use.

Disconnect and lock out all power to the electric strike or access control circuit before beginning work. Verify door handing before installation and use the field reversible feature as needed to match the door swing. Consult applicable local building and fire codes, including NFPA 80 and IBC egress requirements, when installing fail safe hardware in life-safety applications.
