Installation

1. Check Door Type & Lock Position – Confirm that the main metal door/gate has sufficient flat mounting space for the rim lock and that the door can close properly against the door frame.
2. Mark the Cylinder Hole – Use the installation plate as a template and mark the Ø30 mm cylinder hole. The diagram shows the cylinder-hole centre positioned approximately 60 mm from the door edge.
3. Maintain Recommended Clearance – Keep approximately 5 mm recommended distance between the door edge/lock arrangement and the door frame as indicated in the installation diagram. Proper clearance helps prevent the lock from rubbing against the frame.
4. Select Left- or Right-Hand Installation – The mounting plate provides positioning references for both left-hand and right-hand doors. Select the orientation according to the actual door opening direction.
5. Fix the Lock Body – Drill the required mounting holes according to the template and securely mount the electronic rim lock on the door. Make sure the cylinder is correctly aligned with the marked cylinder-hole centre.
6. Install the Door-Frame Locking Part – Position the corresponding locking/receiving part on the door frame so that the lock engages correctly when the door is closed. Check the alignment before applying power.
7. Check Mechanical Movement – Close and open the door manually to confirm that the latch/locking mechanism moves freely and does not experience excessive pressure or obstruction.
8. Install the RF Receiver – Mount the RF receiver in a suitable location near the lock and power supply. Avoid placing it unnecessarily close to large metal surfaces, electronic equipment or strong electromagnetic sources, as these can affect wireless operation.

Wiring

• Power: Connect Power Supply +12V → Remote Receiver +12V and Power Supply GND → Remote Receiver GND.
• Input: The RF receiver receives the wireless command from the programmed remote control at 433.92 MHz.
• Output: Connect Lock Wire 1 → Receiver NO and Lock Wire 2 → Receiver GND, as shown in the supplied wiring diagram.
• Relay Connection: Connect Receiver COM → Receiver +12V, following the connection diagram supplied with the product.
• Remote Receiver: The receiver acts as the interface between the wireless remote and the electronic rim lock, switching its relay when a programmed remote command is received.
• Power Requirement: The RF controller manual specifies DC12V operating voltage. The supplied connection illustration shows a 12V 3A power supply.
• Important: Switch OFF the power before making, changing or checking electrical connections.

Programming

1. Power the RF Receiver – After completing the wiring, switch on the DC12V supply and confirm that the receiver is powered.
2. Select the Required Receiver Mode – The RF controller manual provides Jogging Mode, Self-Locking Mode and Interlock Mode, along with separate timed learning options.
3. Pair the Remote – Press the receiver's learning button according to the desired mode, then press the required button on the remote control. The LED indication confirms successful learning.
4. Jogging Mode – Press the learning button once and then press the desired remote button. The receiver learns the remote for momentary/jogging operation.
5. Self-Locking Mode – Press the learning button twice and then press the desired remote button. The receiver learns the remote for self-locking operation.
6. Interlock Mode – Use the learning-button sequence specified for interlock mode and then press the required remote button to complete learning.
7. Timed Learning – The controller manual provides 5-second, 10-second, 15-second and 20-second delay-learning methods for the corresponding receiver functions.
8. Clear All Learned Remotes – To erase the stored remote controls, press the receiver's learning button eight times. The LED flashes continuously to indicate that the remote controls have been cleared successfully.
9. Test the Remote – After programming, press the learned remote button and verify that the receiver activates the electronic rim lock correctly.
   

Operation

1. Press the Programmed Remote Button – Press the learned button on the supplied RF remote. The receiver detects the wireless signal and activates its programmed relay function.
2. Receiver Operates the Lock – The RF receiver switches its output according to the programmed operating mode, allowing the electronic rim lock to release.
3. Open the Door – Once the lock releases, open the door normally without forcing the door or locking mechanism.
4. Close the Door – After entering or exiting, close the door and ensure that the rim-lock latch aligns correctly with the door-frame receiving section.
5. Use the Selected Mode – In Jogging Mode, the receiver operates momentarily. In Self-Locking Mode, the relay changes state according to successive remote commands. The actual operation depends on the mode programmed into the RF receiver.
6. Use the Mechanical Key When Required – The lock shown in the supplied product image includes a mechanical cylinder/key arrangement, providing an alternative manual method of operating the lock.
7. Maintain Reliable RF Communication – Keep the receiver away from unnecessary metal obstructions and strong electromagnetic interference. If remote response becomes weak, check the remote battery and receiver placement.
   

Troubleshooting

• Problem: Remote does not operate the electronic lock.
  Solution: Check that the RF receiver has DC12V power, verify the receiver wiring, and re-pair the remote using the learning-button procedure.
• Problem: Remote operating range is reduced or inconsistent.
  Solution: Check the remote battery and keep the receiver away from metal walls, large electronic devices and strong electromagnetic fields, as advised in the RF controller manual.
• Problem: Lock does not release after pressing the remote.
  Solution: Check the NO, GND, COM and +12V connections against the supplied wiring diagram. Also check that the door is not putting excessive mechanical pressure on the lock.
• Problem: Remote was previously working but no longer operates the receiver.
  Solution: The remote may have been cleared from the receiver. Re-learn the remote using the required programming mode.
• Problem: Lock operation is mechanically difficult.
  Solution: Check the alignment between the lock body and door frame. The installation diagram shows approximately 60 mm cylinder positioning, a Ø30 mm cylinder hole and a recommended 5 mm clearance.
• Problem: Remote controls need to be removed from the receiver.
  Solution: Use the receiver's clear function. The manual specifies pressing the learning button eight times; continuous LED flashing indicates successful clearing.
  

Common Problems

• Remote not responding – Check receiver power, remote battery and remote pairing.
• Lock not releasing smoothly – Check door/lock alignment and ensure the door is not pressing against the locking mechanism.
