2. Setup and Installation
Careful installation is crucial for the proper functioning and security of your access control system. Ensure all power is disconnected before beginning installation.
2.1 Access Control Keypad Installation
The keypad is designed for surface mounting. Choose a secure, weather-protected location near the entry point. Connect the keypad to the power supply and electric lock according to the wiring diagram (refer to the power supply section for terminal details).

- Mount the keypad securely to a wall or door frame using appropriate screws.
- Connect the power wires (DC12V), lock control wires (NC/NO/COM), and exit button wires (PUSH/GND) to the keypad's terminals.
- If desired, connect a doorbell to the doorbell terminals.
- Ensure all connections are tight and insulated.
2.2 Electric Drop Lock Installation
The electric drop lock is typically installed on the door frame and the corresponding strike plate on the door. Ensure proper alignment for secure locking.

- Mount the main body of the lock to the door frame and the armature plate to the door, ensuring they align perfectly when the door is closed.
- Connect the lock's power wires to the power supply's NC/NO/COM terminals as required by your system configuration (NC mode is default for this lock).
- Test the lock's operation manually before applying power.
2.3 Power Supply Installation
The power supply unit converts AC power to DC 12V for the system and manages the lock's power. It should be installed in a dry, secure location.

- Mount the power supply unit to a wall.
- Connect the AC input (AC100-260V) to a suitable power source.
- Connect the keypad's DC12V and GND to the power supply's +12V and GND terminals.
- Connect the electric lock to the NC/NO/COM terminals based on the lock type and desired operation. For the included electric drop lock, use NC and COM.
- Connect the exit button to the PUSH and GND terminals.
- The delay for the lock can be adjusted from 0 to 30 seconds using the potentiometer on the power supply board.
2.4 Door Exit Button Installation
The exit button allows for convenient egress from the secured area.

5. Troubleshooting
If you encounter issues with your access control system, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Keypad does not power on. | No power to the power supply; faulty wiring; power supply failure. | Check AC input to power supply. Verify DC 12V output. Inspect all wiring connections. |
| Lock does not engage/disengage. | Incorrect wiring (NC/NO); insufficient power; lock mechanism obstruction; faulty lock. | Ensure lock is wired to NC and COM terminals for Fail Safe operation. Check power supply output. Clear any obstructions. Test lock independently if possible. |
| RFID card/password not recognized. | Card/password not programmed; incorrect entry; faulty card. | Verify card/password is correctly programmed (refer to Section 3.1). Re-enter password carefully. Try a different registered card. |
| Exit button does not work. | Incorrect wiring; faulty button. | Check wiring between exit button and power supply (PUSH/GND). Test button continuity if possible. |
| Tamper alarm activates unexpectedly. | Keypad tampered with; sensitive setting. | Inspect keypad for physical damage. Consult keypad manual for alarm sensitivity adjustment. |
