Schlage ND80BDEU Spa 626 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80BDEU SPA 626 is a Grade 1 electrified cylindrical lock configured for storeroom function, designed for commercial access control applications where controlled egress and fail-secure operation are required. It operates on 12-24 volts DC, making it compatible with a wide range of access control power supplies and panel outputs. The lock features a 2-3/4 inch backset and is finished in satin chrome (626). The Sparta lever design meets institutional aesthetic requirements while maintaining Grade 1 mechanical durability. SFIC prep accepts Small Format Interchangeable Cores from major manufacturers, supporting large keying systems without rekeying the lock body.

This lock is suited for interior commercial doors in office buildings, healthcare facilities, educational institutions, and government environments where electrified access control is integrated into a broader security system. Storeroom function means the exterior lever is always locked and can only be released by an electrical signal or a key, while the interior lever remains free for egress at all times. It is typically installed by licensed locksmiths or low-voltage access control integrators working alongside door hardware contractors.

Installation Notes

Installation should be performed by a licensed locksmith or credentialed access control integrator familiar with ANSI cylindrical lock door prep requirements and low-voltage wiring practices. Disconnect access control panel power and verify the door frame is properly reinforced for electrified hardware before installation. Low-voltage wiring should be routed through the door and frame in accordance with NEC guidelines for Class 2 circuits. Verify fail-secure versus fail-safe requirements with the authority having jurisdiction before finalizing the installation.
