The ZKTeco CM‑280S Electromagnetic Lock is engineered as a secure door locking solution for access control installations where a fail‑safe magnetic lock is required. Utilizing electromagnetism, the CM‑280S generates a powerful holding force that keeps doors firmly secured while power is applied. When the power is cut (such as during authorized access or an emergency), the lock instantly releases, ensuring safety compliance and convenient egress.

This overhead electromagnetic lock features surface mounting for easy installation on a wide range of door types including metal, wood, glass, and fire‑rated doors, using appropriate brackets if needed. Its rugged anodized aluminum body ensures long‑lasting performance even in high‑traffic environments. Integrated LED indicators help installers and users quickly assess lock status, while compatibility with standard access control systems makes the CM‑280S ideal for advanced security setups across commercial and institutional locations in Pakistan.
