The security of an electromagnetic lock is impressive. When activated, the lock is made up of an armature and an electromagnet. This magnetic force locks the door and makes it nearly impossible for an intruder to force entry without first deactivating the lock. These locks are designed with failsafe features. They automatically unlock in the event of an electrical failure and allow for safe escape. Due to their combination strength and security, the electromagnetic door lock systems are ideal for high-security environments.
