Schlage ND80PDEU Spa 626 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80PDEU SPA 626 is a Grade 1 electrified cylindrical lock configured for storeroom function, designed for commercial access control applications where fail-secure operation is required. It accepts 12/24 VDC input, meaning the door remains locked on power loss - a critical requirement in security-sensitive environments. The lock features a 2-3/4 inch backset and is finished in satin chrome (626), making it suitable for installations where a clean, professional appearance is expected. It is installed by licensed locksmiths, security integrators, or commercial door hardware contractors.

This lock is intended for commercial interior or exterior doors in office buildings, institutional facilities, schools, and similar environments where controlled access is needed. Storeroom function means the exterior lever is always locked and requires credential or remote electric release to operate, while the interior lever remains free-egress. The Sparta lever trim provides a standard commercial lever profile compatible with cylindrical lock prep doors.

Installation Notes

Installation should be performed by a licensed locksmith or credentialed security hardware contractor in accordance with applicable building and fire codes. Disconnect or de-energize the access control power supply before wiring the lock to avoid damage to the electrified components. Verify door prep dimensions and backset measurement before installation to confirm proper fit. Consult local fire and life-safety codes to confirm fail-secure operation is permitted for the intended door location.
