Schlage ND80PDEL Ath 622 Electrified Cylindrical Lock Fail Safe

Product Description

The SCHLAGE ND80PDEL ATH 622 is a Grade 1 electrified cylindrical lock designed for storeroom function in commercial and institutional access control applications. Operating on 12-24 volts DC, this lock is configured fail safe, meaning the latch retracts and the door is unlocked when power is removed. It features a 2-3/4 inch backset, an Athens-style lever handle, and a conventional cylinder for key override. The flat black coated finish provides a consistent, professional appearance. This hardware is specified by security integrators, locksmiths, and commercial door hardware contractors for controlled-entry applications requiring remote release capability.

The ND80PDEL ATH 622 is suited for storeroom and restricted-access doors in commercial buildings, schools, healthcare facilities, and institutional environments. In storeroom function, the exterior lever is always locked and can only be retracted by key or by energizing the lock electrically. The interior lever allows free egress at all times. This makes it well matched to server rooms, pharmacies, supply closets, and similar spaces where controlled entry is required without impeding exit.

Installation Notes

Installation should be performed by a licensed locksmith or commercial door hardware technician familiar with electrified hardware and access control wiring. Disconnect all power to the access control panel before making electrical connections to avoid damage to the lock mechanism or control board. Verify door preparation dimensions, backset, and cross-bore size before installation, and confirm that the door frame and strike are compatible with cylindrical lock hardware. Low-voltage wiring to the lock should comply with applicable local codes and the NEC for Class 2 circuits.
