6.1 Wiring Diagram
Figure 6.1: Wiring connections for the access control system.
Refer to the wiring diagram above for connecting the keypad to your access control power supply, electric lock, exit button, and doorbell. Ensure all connections are secure and correctly matched to prevent damage to the device or system malfunction.
- 12V: Connect to the positive (+) terminal of a DC12V power supply.
- GND: Connect to the negative (-) terminal of the DC12V power supply and common ground for other devices.
- PUSH: Connect to the exit button.
- OPEN: Typically for connecting to a door sensor or similar input.
- BEL+ / BEL-: Connect to the positive and negative terminals of an external DC12V doorbell.
- NC / COM / NO: Relay output terminals for connecting to an electric lock. Choose NC (Normally Closed) or NO (Normally Open) based on your lock type.
6.2 Typical Installation Scenario
Figure 6.2: Example installation of the access control system.
The diagram illustrates a common setup where the access controller is mounted near the door, connected to a magnetic lock, an exit button on the inside, and a central power supply unit. Ensure the keypad is mounted at an accessible height and in a location protected from extreme weather conditions if installed outdoors.
7. Operating Instructions
The Sebury NN99 access control system supports various methods for granting access.
7.1 Default Settings
The device typically comes with a default programming password. Refer to the small English user manual included in the package for the specific default password and initial programming steps. It is highly recommended to change the default programming password immediately after installation for security reasons.
7.2 Adding Users (Cards/Passwords)
To add new RFID cards or user passwords:
- Enter the programming mode using the master password.
- Follow the specific instructions in the included manual to add a new user ID.
- For RFID cards, present the card to the card reading area. For passwords, enter the desired password and confirm.
- Exit programming mode.
7.3 Granting Access
Users can gain access using one of the following methods:
- RFID Card: Present a programmed RFID key fob or card to the card reading area. The door will unlock.
- Password: Enter the programmed user password on the keypad, then press the '#' (Enter) button. The door will unlock.
- RFID Card + Password: Present a programmed RFID card, then enter the corresponding password and press '#'. The door will unlock. This method provides a higher level of security.

7.4 Doorbell Function
If an external doorbell is connected to the BEL+ and BEL- terminals, pressing the doorbell button on the keypad will activate the doorbell.
8. Maintenance
To ensure the longevity and optimal performance of your access control system, follow these maintenance guidelines:
- Cleaning: Wipe the keypad surface with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components.
- Environmental Conditions: Ensure the device is not exposed to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture. While the RFID key fobs are described as waterproof, the main keypad unit may not be fully weatherproof unless specified.
- Regular Checks: Periodically check all wiring connections for looseness or corrosion. Ensure the electric lock operates smoothly.
- Security: Regularly review and update user access permissions. Change the master password periodically.
9. Troubleshooting
If you encounter issues with your access control system, refer to the following common problems and solutions:
- Device not powering on:
- Check the DC12V power supply connection.
- Verify the power adapter is functioning correctly.
- RFID card not recognized:
- Ensure the card is correctly programmed into the system.
- Confirm the card is a 125KHz EM type.
- Present the card firmly to the card reading area.
- Door not unlocking:
- Check the wiring to the electric lock (NC/NO/COM).
- Verify the power supply to the lock is adequate.
- Ensure the correct access code or card is being used.
- Keypad unresponsive:
- Check for power supply issues.
- If the device is completely frozen, try disconnecting and reconnecting power (power cycle).
- Doorbell not ringing:
