The Corbin Russwin CLX33905-124D is a premium, Grade 1 electrified cylindrical lever lockset engineered for high-security commercial applications requiring dependable electronic access control. Operating on a Fail Secure function, this lock ensures the exterior lever remains locked during power outages to maintain building integrity while always permitting free egress from the inside. Featuring the elegant Georgia (124) lever and D Rose in a satin chrome finish, it is built with ElectroLynx® technology for simplified "plug-and-play" installation via 8-pin connectors. Designed for versatility, it accommodates both 12VDC and 24VDC power requirements with an incredibly low 10mA current draw, making it an efficient and robust solution for heavy-duty doors in hospitals, universities, and government facilities.
Function: Fail Secure - The Fail Secure function ensures the outside lever remains locked when power is removed, maintaining building security during a power outage or system failure. When power is applied, the outside lever unlocks for entry, while the inside lever always allows for free egress at all times.
