Frequently Asked Questions
Q: What types of doors is this electromagnetic lock compatible with?
A: This 280KG electromagnetic door lock is compatible with a wide range of door types, including wooden doors, metal doors, glass doors, and fireproof doors. As long as the armature plate can be mounted flush against the lock body, it will work effectively.
Q: How does a power-on electromagnetic lock work in a power outage?
A: This lock operates in "power-on to lock" (fail-safe) mode, meaning it holds the door shut when electricity is supplied. In the event of a power outage, the magnetic field is released and the door can be opened freely — an important safety feature for emergency egress compliance.
Q: Can I connect this lock to my existing access control system?
A: Yes. This DC 12V electromagnetic lock is designed to integrate seamlessly with standard access control systems including keypad controllers, card readers, push-button exits, remote controllers, and more. Simply wire it into your control panel's 12V output circuit.
Q: What does the built-in MOV (reverse current protection) do?
A: The Metal Oxide Varistor (MOV) protects the lock's internal electronics and your connected access control equipment from voltage spikes that occur when power to the electromagnet is cut. This helps extend the overall life of the lock and prevents damage to your system.
Q: What is the current draw of this electromagnetic lock?
A: The lock draws between 380–430 mA at DC 12V during normal operation. Be sure your power supply can handle this load, especially if you are running multiple locks or other access control devices on the same supply.
