Installation

Step 1 — Select Installation Position

Position the electromagnetic lock and armature plate correctly on the door and frame.

Step 2 — Mount the Lock

Secure the electromagnetic lock body firmly to the appropriate mounting surface using the supplied mounting hardware.

Step 3 — Mount the Armature Plate

Install the armature plate on the door so that it aligns correctly with the electromagnetic lock when the door is closed.

Step 4 — Check Alignment

Close the door and verify that the lock and armature plate make proper contact. Correct alignment is important for achieving the specified holding force.

Step 5 — Connect Power

Connect the lock according to the required 12V/24V DC configuration and the applicable wiring instructions.

Step 6 — Test Operation

Test locking, unlocking and door-status monitoring before putting the system into regular service.

Installation Note: Final installation and wiring should be performed by a qualified technician when required by the access-control system.

Important Installation & Usage Tips

1. Do not overtighten the armature plate screw.
2. Allow the rubber ring to provide flexibility to the armature plate.
3. Keep the magnetic contact surfaces clean.
4. Remove dust, glue, paint or adhesive from the contact surfaces.
5. Ensure the lock and armature plate are properly aligned.
6. Ensure the door closes completely before the magnet engages.
7. Use an appropriate regulated DC power supply.
8. Verify the required voltage before connecting the lock.
9. Use a suitable access-control relay/controller.
10. Test the emergency release function after installation.
11. For glass doors, use the appropriate mounting bracket.
12. Do not drill or modify the lock body unnecessarily.
13. Ensure all mounting screws are securely fixed.
14. Check the door-status feedback wiring when applicable.

Wiring

The EM-602 is a wired electromagnetic lock. It requires a regulated 12V DC or 24V DC power supply and can be connected to an access-control system, push-to-exit button, or remote controller. The EM-602 also provides NO/NC/COM feedback terminals for monitoring the door/lock status.

• Power: Connect the positive (+) power supply to V+ and the negative (–) power supply to V−/GND. Use the correct 12V or 24V DC setting before powering the lock.
• Input: Connect the lock to the access-control relay/output. An authorized access signal interrupts power to release the electromagnetic lock. A normally closed (NC) access-control arrangement is typically used for fail-safe electromagnetic locks.
• Output: The NO/NC/COM feedback contacts provide a dry-contact status signal that can be connected to a compatible access-control panel to monitor the door/lock status.
• Other Connections: A push-to-exit button, remote controller, intercom, biometric reader, RFID/card reader or keypad access controller can be connected through the access-control relay to release the lock. The exact terminal/wire assignment should be followed from the EM-602's supplied wiring diagram.

Programming

The EM-602 itself is primarily an electromagnetic locking device rather than a standalone programmable access controller.

Step 1

Configure the connected access-control system according to its own instructions.

Step 2

Test the door sensor and relay operation after configuration.

Operation

Step 1 — Door Closed

When the door is correctly closed and the electromagnetic lock is powered, the magnet and armature plate engage.

Step 2 — Door Secured

The electromagnetic lock provides up to 600 Lbs (280 kg) holding force when correctly installed and aligned.

Step 3 — Access Granted

When the connected access-control system releases the lock, the electromagnetic holding force is removed and the door can be opened.

Step 4 — Monitoring

The door sensor can be used to monitor the door's status as part of the connected security/access-control system.

Troubleshooting

Problem: Door does not lock

Solution:

• Check that the power supply is connected.
• Verify that the supply is 12V or 24V DC as required.
• Check wiring and connections.
• Ensure the electromagnetic lock and armature plate are correctly aligned.
• Check that the door is fully closed.

Problem: Lock has weak holding force

Solution:

• Check alignment between the magnet and armature plate.
• Ensure both contact surfaces are clean and properly seated.
• Verify the correct DC power supply.
• Check mounting screws and mechanical installation.
• Ensure the installation is capable of achieving the specified holding force.

Problem: Door sensor/status monitoring is not working

Solution:

• Check the sensor wiring.
• Check connections to the access-control/security system.
• Verify that the door is properly aligned and closing completely.
• Check the connected controller configuration.

Common Problems

1. Lock does not hold the door securely – Check power supply, alignment and contact between the lock and armature plate.

2. Lock does not release – Check the access-control release signal and wiring.

3. Door sensor does not show the correct status – Check sensor connections and door alignment.

4. Lock installation is misaligned – Reposition the lock/armature plate so that the two surfaces meet correctly when the door closes.
