Schlage ND12DEL Ath 625 Rx Electrified Cylindrical Lock

Product Description

The SCHLAGE ND12DEL ATH 625 RX is a Grade 1 electrified cylindrical lock configured for exit function operation. It accepts 12 to 24 volts DC and is wired fail safe, meaning the latch retracts and the door is free to open when power is removed. The Athens lever handle and bright chrome (625) finish make it suited for commercial corridors, stairwells, and exit routes where both aesthetics and access control are required. A 2-3/4 inch backset fits standard commercial door preparations. The RX option provides request-to-exit signaling. No cylinder override is included in this configuration.

This lock is intended for commercial and light-institutional applications where electrified exit hardware is required on interior or vestibule doors. The exit function allows free egress from the secure side at all times, with electric control of entry from the unsecured side. Typical installations include office suites, server rooms, and access-controlled corridor doors. A licensed locksmith, security integrator, or electrician familiar with low-voltage access control systems typically handles installation and integration.

Installation Notes

Installation should be performed by a licensed locksmith or low-voltage access control technician familiar with ANSI cylindrical lock door preps and local electrical codes. Confirm door backset, cross bore, and edge bore dimensions before installation. Disconnect and lock out the access control power supply before wiring the lock to prevent unintended operation. Verify fail safe or fail secure requirements with the authority having jurisdiction before finalizing the wiring configuration.
