5. Operating Instructions
5.1 Keypad Operation
The keypad allows access via a numerical code or RFID card/keyfob.
- Default Access Code: The default access code is typically 1234.
- Entering an Access Code: Enter your 4-digit code followed by the '#' key. The door will unlock for a preset duration.
- Adding User Codes:
- Enter Programming Mode: Press '*' then enter the Master Code (default: 123456) then '#'.
- Add User Code: Press '1' then enter a 3-digit User ID (e.g., 001) then '#'. Enter the new 4-digit User Code then '#'. Repeat for additional users.
- Exit Programming Mode: Press '*' to save and exit.
- Adding RFID Cards/Keyfobs:
- Enter Programming Mode: Press '*' then enter the Master Code (default: 123456) then '#'.
- Add Card: Press '1' then present the RFID card/keyfob to the keypad. The keypad will beep to confirm. Repeat for additional cards.
- Exit Programming Mode: Press '*' to save and exit.
- Deleting User Codes/Cards: Consult the specific keypad manual for detailed instructions on deleting individual users or resetting the keypad.

5.2 Remote Control Operation
The remote transmitters allow convenient unlocking from a distance.
- Pairing Remotes: The remotes are typically pre-paired with the receiver. If re-pairing is needed, refer to the remote receiver's specific instructions. Usually, this involves pressing a learning button on the receiver and then a button on the remote.
- Unlocking: Press the unlock button on the remote transmitter. The door will momentarily unlock.
5.3 Exit Button Operation
The push-to-exit button provides a simple way to exit from the secured area.
- Exiting: Press the exit button. The magnetic lock will disengage, allowing the door to open.
6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your access control system.
- Cleaning: Clean the keypad and magnetic lock surfaces with a soft, dry cloth. Avoid abrasive cleaners or solvents.
- Check Connections: Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
- Magnetic Lock Alignment: Ensure the magnetic lock and armature plate remain properly aligned. Misalignment can reduce holding force.
- Battery Replacement (Remotes): If remote controls become unresponsive, replace their internal batteries.
7. Troubleshooting
If you encounter issues with your access control system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Magnetic lock does not engage or holds weakly. | Incorrect wiring; insufficient power; misalignment of lock and armature plate; improper mounting. | Verify all wiring connections (refer to Section 4.2). Ensure the power supply is providing stable 12VDC. Check alignment and adjust if necessary. Confirm the magnetic lock and armature plate are securely mounted, potentially requiring appropriate brackets for your door type. |
| Keypad is unresponsive or not powering on. | No power to keypad; faulty wiring; keypad malfunction. | Check power connections to the keypad from the power supply. Ensure the power supply unit is receiving input power. Verify wiring integrity. |
| Cannot add more than 4 users to the keypad. | Keypad user capacity limit reached; incorrect programming steps. | Some keypads have a limited number of user slots. Consult the specific keypad's detailed manual for its maximum user capacity and advanced programming options. Ensure you are following the correct sequence for adding users (Section 5.1). |
| Remote control does not unlock the door. | Remote battery low/dead; remote not paired; remote receiver issue. | Replace the battery in the remote transmitter. Re-pair the remote with the receiver (refer to Section 5.2). Check wiring to the remote receiver. |
| Exit button does not release the lock. | Incorrect wiring; faulty button. | Verify wiring connections for the exit button to the power supply control unit. Test the button for continuity if possible. |
