4. Setup and Installation
Important Considerations:
- This lock is designed for outswinging doors. For inswinging door applications, specific Z & L brackets are required (e.g., FPC-5191 for 300lb, FPC-5192 for 600lb, FPC-5193 for 1200lb). These brackets are sold separately.
- Ensure the installation surface is stable and capable of supporting the lock's weight and holding force.
Installation Steps:
- Prepare the Door and Frame: Identify the mounting location on the door frame (for the electromagnet) and the door leaf (for the armature plate).
- Use the Template: Affix the provided installation template to the door frame and door leaf according to the instructions. This ensures accurate drilling for the mounting holes.
- Drill Holes: Carefully drill the necessary holes as indicated by the template.
- Mount the Electromagnet: Separate the cover from the electromagnet body. Secure the mounting plate to the door frame using the provided screws. Hang the electromagnet body onto the mounting plate and secure it with the set screws.
- Mount the Armature Plate: Insert the guide pins into the armature plate. Fasten the armature plate to the door leaf using the screw and inner hex nut. Ensure rubber washers are used to allow slight adjustment for optimal contact.

This video provides visual guidance on mounting the lock and armature plate on an outswinging door, as well as details on wiring and power consumption.
Wiring and Power:
- Voltage Selection: The lock supports dual voltage (12V or 24V). Inside the terminal, a jumper allows you to select the desired voltage. The default setting is typically 12V. Refer to the detailed wiring diagram in the included user guide for specific jumper positions.
- Power Connection: Connect the red wire to the positive (+) terminal of your power supply and the black wire to the negative (-) terminal.
- Door Status Monitoring (Optional): A white wire is provided for door status monitoring. This can be connected as a hard-wired alarm contact to your access control system to indicate if the door is open or closed. If this feature is not required, the white wire can be safely cut.
- Normally Open/Closed Outputs: The lock also features Normally Open (NO), Normally Closed (NC), and Common (C) outputs located in the green terminal block. These can be used for various access control applications.

5. Operation
Fail-Safe Mechanism:
The Visionis VIS-ML600LED is a fail-safe lock. This means that in the event of a power failure or intentional power cut, the lock will automatically unlock. This feature is crucial for emergency egress and safety regulations.
LED Indicator:
The integrated LED indicator provides immediate visual feedback on the lock's status:
- Green LED: Indicates that the lock is powered, engaged, and securely holding the door closed.
- Red LED: Indicates that the lock is powered but the armature plate is not properly engaged with the electromagnet, or there is a misalignment.
6. Maintenance
To ensure optimal performance and longevity of your Visionis VIS-ML600LED electromagnetic lock, regular maintenance is recommended:
- Cleaning: Periodically clean the surfaces of both the electromagnet and the armature plate with a soft, dry cloth. Ensure no dust, dirt, or debris accumulates, as this can reduce the holding force.
- Connection Check: Inspect all wiring connections to ensure they are secure and free from corrosion or damage. Loose connections can lead to intermittent operation or power loss.
- Alignment Verification: Regularly check the alignment between the electromagnet and the armature plate. Proper alignment is critical for maximum holding force and correct LED status indication.
- Screw Tightness: Verify that all mounting screws for both the lock body and the armature plate remain tight.
7. Troubleshooting
If you encounter issues with your electromagnetic lock, refer to the following troubleshooting guide:
- Lock Not Engaging or Holding Force is Weak:
- Check the power supply to ensure it is providing the correct voltage (12V or 24V) and sufficient current.
- Ensure the armature plate and electromagnet surfaces are clean and free of debris.
- Verify proper alignment between the electromagnet and the armature plate. Adjust if necessary.
- Check the rubber washers on the armature plate screw; they allow for slight movement to ensure full contact.
- LED Indicator is Red:
- This indicates the lock is receiving power but is not fully engaged. This is often due to misalignment or an obstruction preventing full contact between the electromagnet and armature plate.
- Adjust the door or armature plate to achieve proper contact.
- Lock Not Unlocking:
- Since the lock is fail-safe, it should unlock when power is removed. Verify that the power supply to the lock is being completely cut off by your access control system or switch.
- Check for any short circuits or wiring issues that might be maintaining power to the lock.
- Excessive Power Consumption or Heat:
- Ensure the correct voltage (12V or 24V) is selected via the internal jumper. Incorrect voltage can lead to improper operation and heat.
- Verify the power supply capacity meets the lock's requirements (e.g., 500mA for 12V or 250mA for 24V for 600lb/1200lb models).
