Schlage ND80BDEU Ath 625 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80BDEU ATH 625 is a Grade 1 electrified cylindrical lock configured for storeroom function in commercial and institutional access control applications. It operates on 12-24 volts DC and is fail secure, meaning the latch remains locked if power is interrupted. The lock features a 2-3/4 inch backset and mounts an Athens lever on the outside. It is prepared for Small Format Interchangeable Core (SFIC) cylinders, allowing integration into existing keying systems without replacing the entire lock body. Finished in Bright Chrome (626/625), it is suited for high-traffic doors requiring electrified access control with a durable, polished appearance. Licensed locksmiths and commercial door hardware technicians are the primary installers.

This lock is intended for commercial interior and perimeter doors where access is controlled electronically. Storeroom function means the outside lever is always locked and can only be retracted by credential or electric release, while the inside lever provides free egress at all times. The SFIC prep accommodates interchangeable core cylinders for facilities running large master key systems. The fail secure configuration makes it appropriate for server rooms, pharmacies, restricted storage areas, and similar spaces where door security must be maintained during a power loss.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with electrified hardware and low-voltage wiring. Disconnect and lock out all power to the access control circuit before wiring or servicing the lock. Low-voltage wiring must comply with NEC Article 725 requirements for Class 2 circuits. Verify door prep dimensions, backset, and handing before installation, and confirm the access control panel output matches the 12-24 VDC input requirement of the lock.
