Schlage ND80LDEL Ath 626 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80LDEL ATH 626 is a Grade 1 electrified cylindrical lock configured for storeroom function, designed for commercial access control applications where fail-safe electric release is required. Operating on 12-24 volts DC, this lock remains unlocked when power is applied and locks upon power loss, making it suitable for life-safety egress requirements. It features the Athens lever trim and ships less cylinder, allowing the integrator to supply a specified core. The 2-3/4 inch backset fits standard commercial door preparations, and the 626 satin chrome finish provides a clean, professional appearance consistent with institutional and commercial hardware standards.

This lock is used in commercial and institutional settings where controlled entry is required on doors that must allow free egress during power failures. Typical installations include office storerooms, server rooms, and secured interior doors in schools, healthcare facilities, and government buildings. The storeroom function keeps the outside lever locked at all times unless electrically released or mechanically actuated, while the inside lever allows free egress. Licensed locksmiths, access control integrators, and commercial door hardware technicians are the primary installers.

Installation Notes

Installation should be performed by a licensed locksmith or certified access control integrator familiar with commercial door hardware and low-voltage wiring practices. Disconnect all power to the access control circuit before making electrical connections to avoid damage to the lock or control panel. Cylinder selection and installation must be completed on-site; the lock ships without a cylinder. Consult local building and fire codes, including applicable IBC egress requirements, to confirm that fail-safe configuration is permitted for the intended door application.
