Schlage L283-471 Eu Fail Secure Electric Lock Case

Product Description

The SCHLAGE L283-471 EU is a fail secure electric lock case designed for commercial access control applications. In a fail secure configuration, the deadbolt remains locked when electrical power is interrupted, maintaining security during outages. This lock case includes an integrated deadbolt position monitor, which provides a signal output to indicate bolt status for use with access control panels or building management systems. The unit is field reversible, allowing installation on either hand of door without special hardware. It is intended for use with L9492 and L9494 series mortise lock bodies.

This lock case is suited for commercial and institutional door hardware applications where access control integration is required. Typical installations include office buildings, schools, healthcare facilities, and other commercial environments where monitored, electrically controlled deadbolt locksets are specified. Because the unit is field reversible, installers can adapt it to left-hand or right-hand door configurations during initial install without returning the hardware for a specific handing from the factory. Compatible host locksets are the L9492 and L9494 series mortise locks.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with commercial mortise lock systems and access control wiring. Disconnect and lock out all electrical power to the access control circuit before servicing or installing the lock case. Verify door handing before setting field reversibility to avoid reassembly during commissioning. Low-voltage wiring for the electric strike circuit and monitor contacts should comply with applicable local codes and NEC requirements for access control systems.
