The ABUS CodeLoxx CLX-LPxA-EF Alarm AE255F Proximity Security is an electronic double-knob cylinder for professional access control systems. As part of the CodeLoxx system, it combines modern proximity technology with advanced security features, enabling convenient and reliable access control in commercial buildings, public facilities, and security-sensitive areas.

Operation is via a tamper-proof chip key or compatible proximity transponder. This allows doors to be opened quickly and contactlessly, minimizing mechanical wear and significantly increasing ease of use. The system enables clear access control and ensures that only authorized personnel gain entry.

A key feature of this cylinder is the integrated radio module in the inner knob. In conjunction with the AE255F evaluation unit, an intruder alarm system can be conveniently armed and disarmed. This links access control and alarm management, reducing operating errors and simplifying security processes.

The security version offers additional mechanical protection through enhanced drill protection and a robust cylinder construction. This significantly increases tamper protection and makes the cylinder suitable for security-critical doors.

Thanks to its modular extension system, the cylinder can be flexibly adapted to different door thicknesses. This allows the ABUS CodeLoxx CLX-LPxA-EF to be easily integrated into new or existing locking systems. In combination with other CodeLoxx components, it creates a high-performance access solution that combines security, convenience, and flexible management in a single system.
