If you are looking for a secure and reliable way to keep your doors locked, you might want to consider installing a magnetic door lock. These locks use a magnet to keep the door securely closed, and they are an excellent choice for high-security areas where you need to keep unauthorized personnel out. In this article, we will walk you through the steps of wiring a magnetic door lock and provide you with a comprehensive wiring diagram. So, let’s begin.
What is a Magnetic Door Lock?
A magnetic door lock is a type of locking mechanism that uses a magnetic force to keep the door closed. These locks consist of two main components: an electromagnet and an armature plate. The electromagnet is mounted on the door frame, while the armature plate is mounted on the door itself. When the door is closed, the electromagnet is energized, creating a magnetic field that attracts the armature plate, keeping the door locked.
One of the advantages of magnetic door locks is that they do not require a key to operate. Instead, they are usually controlled by an access control system, such as a keypad or card reader, which allows authorized personnel to unlock the door. This makes them a popular choice for commercial and industrial applications where security is of utmost importance.
Wiring a Magnetic Door Lock
The first step in wiring a magnetic door lock is to determine the power supply. Magnetic door locks typically operate on either 12 or 24 volts DC, so you will need to ensure that your power supply is compatible with your lock. Once you have determined the voltage of your lock, you can connect the power supply to the lock’s control board.
Most magnetic door locks have a control board that is mounted near the lock itself. This board contains the wiring terminals for the power supply, the door position sensor, and the access control system. To wire the lock, you will need to connect the positive and negative terminals of the power supply to the control board. You will also need to connect the door position sensor, which tells the control board whether the door is open or closed.
The final step in wiring a magnetic door lock is to connect the access control system. This could be a keypad, card reader, or other access control device that allows authorized personnel to unlock the door. To connect the access control system, you will need to run wires from the control board to the access control device.

| 2 | Black | Negative Power Supply |
| 3 | Green | Door Position Sensor – NC |
| 4 | White | Door Position Sensor – NO |
| 5 | Blue | Access Control System – Common |
| 6 | Brown | Access Control System – Normally Open |
| 7 | Orange | Access Control System – Normally Closed |
FAQs
1. How do I know if my power supply is compatible with my magnetic door lock?
You will need to check the voltage requirements of your magnetic door lock and ensure that your power supply provides the same voltage. Most magnetic door locks operate on either 12 or 24 volts DC.
2. How do I connect the door position sensor?
The door position sensor should be connected to the control board using two wires. These wires are typically color-coded, with green representing the normally closed (NC) connection and white representing the normally open (NO) connection. Consult your lock’s user manual for specific wiring instructions.
3. Can I use a magnetic door lock on an exterior door?
Yes, magnetic door locks can be used on exterior doors, but they may not be suitable for all applications. If you are considering using a magnetic door lock on an exterior door, you should consult a security professional to ensure that it is the right choice for your specific needs.
4. How do I troubleshoot my magnetic door lock?
If your magnetic door lock is not working properly, you should first check the power supply and wiring connections to ensure that they are secure and properly connected. You should also check the door position sensor and access control system to ensure that they are functioning correctly. If you are still experiencing issues, consult your lock’s user manual or contact the manufacturer for assistance.
5. Do magnetic door locks require maintenance?
Magnetic door locks do not require much maintenance, but you should periodically clean the lock and check for signs of wear or damage. You should also check the power supply and wiring connections to ensure that they are secure and free of corrosion. If you notice any issues, contact a security professional for assistance.
With this guide, you should now be able to wire a magnetic door lock with ease. Always remember to consult your lock’s user manual and manufacturer’s instructions for detailed wiring requirements and specifications.
