Schlage ND80PDEL Spa 626 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80PDEL SPA 626 is a Grade 1 electrified cylindrical lock configured for storeroom function with a fail-safe electric release. Rated for 12-24 volts DC operation, this lock is designed for commercial access control applications where the door must default to the unlocked position upon power loss. The Sparta lever trim and satin chrome (626) finish provide a clean, professional appearance suited to high-traffic commercial environments. Licensed locksmiths, access control integrators, and commercial door hardware technicians are the primary installers of this hardware.

This lock is intended for commercial interior or exterior doors where electrified access control is required alongside mechanical storeroom-style security. Storeroom function means the outside lever is always locked and can only be retracted by credential, key, or electric signal, while the inside lever remains free egress at all times. The fail-safe configuration ensures the outside lever retracts and allows entry when power is interrupted, making it appropriate for life-safety egress paths in offices, healthcare facilities, and institutional buildings. The 2-3/4 inch backset accommodates standard commercial door preps.

Disconnect and lock out all power to the access control system before wiring the electric strike circuit. Low-voltage wiring must comply with applicable NEC Article 725 requirements for Class 2 circuits.
