Schlage ND12DEL Ath 626 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND12DEL ATH 626 is a Grade 1 electrified cylindrical lock configured for exit function applications. It operates on 12 to 24 volts DC and is wired fail safe, meaning the lock releases when power is removed. The Athens lever trim and satin chrome finish (626) give it a clean, professional appearance suited to commercial and institutional settings. With a 2-3/4 inch backset and no cylinder override, this lock is intended for controlled egress points where electrical release is required and mechanical key bypass is not. Licensed locksmiths and commercial door hardware installers are the typical trades for this product.

This lock is designed for commercial interior doors in offices, schools, healthcare facilities, and institutional buildings where Grade 1 security and electrified access control are required. The exit function allows free egress from the secured side while controlling entry from the exterior. It is commonly installed as part of an access control system tied to a panel, credential reader, or request-to-exit device. The fail safe configuration makes it appropriate for doors on egress paths where life safety codes require the door to unlock upon power loss.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with electrified hardware and applicable access control wiring practices. Disconnect power to the access control panel before making electrical connections to avoid damage to the lock solenoid or panel board. Verify door prep dimensions, backset, and handing before installation. Consult local building and fire codes, including NFPA 80 and IBC egress requirements, when installing hardware on rated or egress doors.
