Maintenance

  • Cleaning: Wipe the keypad and magnetic lock surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents.
  • Weather Protection: The keypad is IP68 rated for outdoor use, but regular inspection for debris or water ingress around seals is recommended, especially in harsh weather conditions.
  • Cable Inspection: Periodically check all wiring connections for signs of wear, damage, or loose connections.
  • Power Supply: Ensure the power supply unit is in a well-ventilated area and free from obstructions.

Troubleshooting

  • Lock does not engage/disengage:
    • Check all power connections to the magnetic lock and power supply.
    • Verify the power supply is receiving input power and providing DC12V output.
    • Ensure the magnetic lock and armature plate are properly aligned and free of obstructions.
    • In NC (fail-safe) mode, a power outage will unlock the door. Restore power if this is the case.
  • Keypad not responding:
    • Check power connection to the keypad.
    • Ensure the keypad is securely mounted and its internal connections are intact.
  • Fingerprints/Cards/Passwords not recognized:
    • Ensure the fingerprint sensor is clean and your finger is placed correctly.
    • Verify the RFID card is presented correctly to the reader.
    • Double-check the entered password.
    • If fingerprints were lost after a power cycle, they may need to be re-registered.
  • Remote control not working:
    • Check the battery in the remote control.
    • Ensure the remote receiver is powered and correctly wired.
    • Verify the remote control is paired with the receiver.
  • Doorbell not ringing:
    • Check wiring between the keypad and the doorbell unit.
    • Ensure the doorbell unit is receiving power.

Note:

Some users have reported that fingerprint data may be lost after a power cycle, requiring re-registration. RFID cards and codes typically retain their programming.
