Schlage ND80PDEU Ath 619 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80PDEU ATH 619 is a Grade 1 electrified cylindrical lock configured for storeroom function with a fail-secure operation. It accepts 12/24 VDC input and features the Athens lever in a satin nickel (619) finish. Designed for commercial access control applications, this lock requires power to retract the latch, meaning the door remains locked during a power loss. With a 2-3/4 inch backset, it fits standard commercial door preparations and integrates into hardwired access control systems. Licensed locksmiths, security integrators, and commercial door hardware installers are the primary tradespeople who specify and install this hardware.

This electrified cylindrical lock is suited for interior commercial doors where controlled, one-time or scheduled access is required from the exterior while allowing free egress from the interior. Storeroom function means the exterior lever is always locked and can only be released by an electrical signal or a key - the interior lever remains free at all times. Typical installations include server rooms, pharmacies, stock rooms, and secured office areas within commercial and institutional buildings.

Installation Notes

Installation should be performed by a licensed locksmith or qualified security integrator familiar with electrified door hardware and applicable local codes. Disconnect power to the access control system before wiring the lock to avoid damage to the electronics. Verify door preparation dimensions, including backset and cross-bore diameter, match the lock specifications before installation. Consult the manufacturer wiring diagram for proper voltage selection and connection to the access control panel.
