Schlage ND80LDEU Rho 626 Rx Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80LDEU RHO 626 RX is a Grade 1 electrified cylindrical lock configured for storeroom function with fail-secure operation. It accepts 12-24 volts DC, making it compatible with a wide range of access control power supplies. The lock ships without a cylinder installed, allowing the integrator to spec the appropriate core for the project. The Rhodes lever trim and satin chrome finish suit commercial interior applications. A built-in Request to Exit (REX) function supports integration with access control panels that require egress signal feedback. This hardware is specified and installed by licensed security integrators, locksmiths, or commercial door hardware contractors.

This lock is designed for commercial doors requiring controlled access on the secure side with free egress on the interior. The storeroom function keeps the exterior lever locked at all times, releasing only on valid electrical or mechanical credential. The 2.75-inch backset fits standard commercial door preparations. The REX output allows the latch retraction or lever movement to trigger an access control panel event, reducing nuisance alarms on monitored exit points. Fail-secure operation means the lock remains locked during a power loss, making it appropriate for security-sensitive storerooms, server rooms, and restricted-access areas.
