Product Description
The ZKTeco CM-280S Overhead Electromagnetic Lock is a high-strength security locking solution designed for modern access control systems. It uses powerful electromagnetic force to securely lock doors until power is released through an access control device such as a fingerprint machine, RFID reader, or intercom system.
With a holding force of up to 600lbs (approximately 280kg), this lock ensures reliable security for single doors in commercial and residential environments. Its overhead installation design makes it suitable for glass doors, wooden doors, and metal doors, providing flexible installation options.
The CM-280S operates on a fail-safe mechanism, meaning the door automatically unlocks during power failure, ensuring safety compliance. It is widely used in offices, banks, buildings, and secure entry points.
