Medeco has added the Nexgen XT electronic cylinder to its Smart SFIC Solutions line. The cylinder enables facilities that use small format interchangeable core (SFIC) cylinders to quickly and easily retrofit with an electronic cylinder. Features include user scheduling, audit logs of entry and key expiration. The unit requires no wiring, hardware changes, and door or frame modifications. Keys can be programmed to operate on specific schedules or times, or have expirations set for administrators wishing to limit long-term access to a particular area.
