Schlage ND80LDEU Ath 626 Rx Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80LDEU ATH 626 RX is a Grade 1 electrified cylindrical lock configured for storeroom function with fail-secure operation. It accepts 12 to 24 volts DC, making it compatible with a wide range of access control power supplies. The Athens lever trim and satin chrome (626) finish give it a clean, professional appearance suited to commercial environments. The lock ships less cylinder, meaning the installer supplies the appropriate core. A built-in request-to-exit (REX) function allows the lock to signal the access control system when the lever is operated from the secured side.

This lock is designed for commercial doors requiring controlled entry and free egress. Storeroom function keeps the outside lever locked at all times - entry is granted only by credential or remote release - while the inside lever always allows free exit. The 2.75-inch backset fits standard commercial door preps. Typical installations include server rooms, storage areas, restricted-access corridors, and similar applications where continuous locking with electric release is required.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with ANSI Grade 1 cylindrical hardware. Verify door prep dimensions - backset, cross-bore, and edge-bore - match lock specifications before installation. Disconnect and lock out all power to the access control system before wiring the lock. Low-voltage wiring must comply with NEC Article 725 requirements for Class 2 circuits.
