4. Setup and Installation
This magnetic lock is designed for flush mount (embedded) installation. Ensure your door frame and door are suitable for this type of installation before proceeding.
4.1 Door Compatibility
The lock is suitable for various door types, including Wooden Doors, Metal Doors, and Fireproof Doors.
4.2 Installation Steps (General Guidance)
- Prepare the Door Frame: Create a recess in the door frame to embed the main electromagnetic lock body. Ensure the dimensions match the lock's specifications.
- Mount the Electromagnetic Lock: Secure the electromagnetic lock body into the prepared recess using the provided screws. Ensure it is flush with the door frame surface.
- Prepare the Door: Mount the armature plate to the door. The armature plate should align precisely with the electromagnetic lock when the door is closed. Use the provided screws and ensure the rubber ring allows for slight adjustment.
- Wiring: Connect the lock to your 12V DC power supply and access control system according to the wiring diagram. Ensure all connections are secure and insulated.
- Test Operation: After installation and wiring, test the lock's functionality with your access control system. Verify that the door locks when power is applied and unlocks when power is removed.

5. Operating Instructions
The YUHANUS magnetic lock operates in NC (Normally Closed) mode, which is a fail-safe configuration:
- Locked State: When power is supplied to the electromagnetic lock (DC 12V), the electromagnet attracts the armature plate, holding the door securely shut.
- Unlocked State: When the power supply to the electromagnetic lock is interrupted (e.g., via an access control system, exit button, or power failure), the magnetic force is released, allowing the door to open.
6. Maintenance
Proper maintenance ensures the longevity and reliable operation of your magnetic lock.
- Cleanliness: Regularly clean the surface of both the electromagnetic lock and the armature plate. Dust, glue, or adhesive residue can reduce the holding force.
- Armature Plate Screw: Do not overtighten the screw of the armature plate. Loosen it slightly to allow the rubber ring to provide proper elasticity, enabling the armature plate to adjust itself to the appropriate position for optimal contact with the electromagnet.
- Wiring Inspection: Periodically check all wiring connections for signs of wear, corrosion, or looseness. Ensure all connections are secure and properly insulated.

7. Troubleshooting
If you encounter issues with your magnetic lock, consider the following:
- Lock Not Holding:
- Check power supply: Ensure the lock is receiving a stable 12V DC power.
- Inspect surfaces: Clean the contact surfaces of both the electromagnet and armature plate.
- Adjust armature plate: Ensure the armature plate is not overtightened and can pivot slightly to make full contact.
- Verify alignment: Confirm the armature plate aligns perfectly with the electromagnet when the door is closed.
- Door Not Unlocking:
- Check power interruption: Ensure the access control system or exit button is successfully cutting power to the lock.
- Inspect wiring: Look for any short circuits or incorrect wiring that might be maintaining power to the lock.
- Intermittent Operation:
- Check for loose connections in the wiring.
- Ensure the power supply is stable and not fluctuating.
