Schlage ND80PDEU Rho 622 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80PDEU RHO 622 is a Grade 1 electrified cylindrical lock configured for storeroom function. It operates on 12/24 VDC and is fail secure, meaning the latch remains locked when power is lost. The lock features a Rhodes lever handle, a conventional cylinder for key override, and a 2-3/4 inch backset. Finished in flat black coated (622), this unit is designed for commercial access control applications where reliable electrified locking is required. Installation and service are typically handled by licensed locksmiths, access control technicians, or commercial door hardware contractors.

This lock is suited for storeroom and secured-entry applications in commercial and institutional buildings. The storeroom function keeps the outside lever locked at all times, requiring either a key or an electrical signal to allow entry. This makes it appropriate for server rooms, supply closets, pharmacies, and similar controlled-access spaces. The 12/24 VDC dual-voltage capability allows integration with a wide range of access control panels and power supplies without requiring a dedicated transformer match.
