- Locking: When power is supplied, the electromagnet creates a strong bond with the armature plate, locking the door.
- Unlocking: Access is triggered by an access control system (like a biometric reader, keypad, or RFID card) that temporarily cuts the power, allowing the door to open.
- Fail-Safe Mechanism: EM locks are inherently fail-safe. If the building loses power or there is an emergency, the magnetic field drops, instantly unlocking the doors to ensure safe egress.
- Holding Force: Most standard doors use a 600 lbs (approx. 270 kg) or 1200 lbs (approx. 540 kg) holding force.
- Door Compatibility: They work seamlessly with wooden, glass, and metal doors. [1]
