Schlage ND80BDEU Spa 625 Rx Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80BDEU SPA 625 RX is a Grade 1 electrified cylindrical lock configured for storeroom function. It operates on 12-24 volts DC and is factory-set fail secure, meaning the latch remains locked when power is interrupted. The lock features the Sparta lever trim and is finished in Bright Chrome (625). It includes a Small Format Interchangeable Core (SFIC) prep, allowing facilities teams to rekey using a compatible SFIC cylinder without removing the lock body. This hardware is installed by licensed locksmiths, access control integrators, and commercial door contractors on new construction and retrofit projects.

This lock is designed for commercial interior and perimeter doors requiring controlled electrified access. The storeroom function keeps the exterior lever locked at all times - access is granted by credential or remote electrical signal only, while the interior lever remains free for egress. The 2-3/4 inch backset suits standard commercial hollow metal and wood door preps. The Request to Exit (RX) feature sends a signal to the access control panel when the interior lever is used, supporting audit trail and door-held-open monitoring requirements common in healthcare, education, and government facilities.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with ANSI-grade cylindrical lock hardware and low-voltage wiring practices. Disconnect power to the access control panel and any door-mounted wiring before beginning installation. Route low-voltage wiring through the door and frame per the hardware template, keeping signal wires separated from high-voltage runs in compliance with NEC guidelines. Confirm fail secure versus fail safe requirements with the authority having jurisdiction before final configuration.
