This reliable and robust cylinder provides secure, controlled and convenient access. It was specifically designed for use with panic doors with automatic reset of the locking nose. It is operated using the read-protected ABUS Seccor chip key. The cylinder has additional plating for even more protection against break-ins. It allows for contactless operation for fast and easy access control owing to its proximity function. A special advantage of this cylinder is the wireless module in the inside knob, which allows for incredibly easy operation of the alarm system and countless control functions in conjunction with the AE255F evaluation unit.
