Schlage ND80PDEU Ath 622 Electrified Cylindrical Lock Fail Secure

Product Description

The SCHLAGE ND80PDEU ATH 622 is a Grade 1 electrified cylindrical lock configured for storeroom function with fail-secure operation. It accepts 12 or 24 VDC input, making it compatible with a wide range of access control power supplies. The Athens lever design pairs with a conventional cylinder, and the flat black coated finish provides a clean, consistent appearance in commercial interiors. A 2-3/4-inch backset fits standard commercial door prep. This lock is installed by licensed locksmiths, security integrators, or commercial door hardware technicians as part of an access-controlled entry system.

This lock is suited for commercial and institutional applications where door access must be controlled electronically while maintaining mechanical key override capability. Storeroom function means the outside lever is always locked and can only be unlocked by credential or key - the inside lever remains free egress at all times. Typical installations include storage rooms, server rooms, back-of-house doors, and restricted-access areas in office, healthcare, education, and retail environments. The fail-secure configuration keeps the door locked during a power loss, which is the preferred mode for security-critical openings.

Installation Notes

Installation should be performed by a licensed locksmith or qualified security hardware technician familiar with electrified door hardware and access control wiring. Disconnect power to the access control system before wiring the lock. Verify door prep dimensions - backset, cross bore, and edge bore - match the lock specification before installation. Consult applicable local codes and the door manufacturer's requirements for electric hardware on rated assemblies.
