- Door Magnetic Detection Setting: Configure whether to turn off or turn on the door magnetic alarm. This also involves setting up an external alarm switch.
- Security Alarm Mode Setting: Choose between turning off security mode, turning on deadlock (lockout) mode, or turning on alarm mode.
- Data Transmission: This feature allows for the transmission of user card and user password data between compatible machines. Both machines must be from our company and support this function.
- Sound & Light Setting: You can toggle the machine's sound (on/off) and the red indicator light (on/off).

7. Troubleshooting
- Device Not Responding:
- Check the power supply connections to ensure the device is receiving adequate power (DC 9-18V).
- Verify all wiring connections are secure and correct according to the diagrams in Section 3. - Fingerprint Not Recognized:
- Ensure the fingerprint sensor is clean and free of dirt or moisture.
- Try re-enrolling your fingerprint in the system or via the Tuya app.
- Ensure your finger is placed correctly and covers the entire sensor area. - RFID Card Not Working:
- Confirm that you are using a compatible 125KHz EM card.
- Re-enroll the RFID card if it was previously working.
- Ensure the card is held within the 2-6 cm reading range. - Door Not Unlocking/Locking:
- Check the connection to the electric lock. Ensure it is properly wired to the relay output (NO, NC, COM).
- Verify the door opening delay time setting. If set too short, the lock might re-engage prematurely.
- If using multi-user combined unlock, ensure all required users have authenticated. - Tuya App Connectivity Issues:
- Make sure Bluetooth is enabled on your smartphone.
- Ensure the device is within Bluetooth range.
- Try restarting the TuyaSmart app or your phone.
- Check for app updates in your phone's app store. - Keypad Backlight Not Working:
- Check the sound & light settings in the device's programming mode to ensure the backlight is enabled.
8. User Tips
- Master Code Security: Change the default Master Code immediately after installation to a strong, unique password to prevent unauthorized access to programming settings.
- Fingerprint Enrollment: When enrolling fingerprints, try to capture multiple angles of your finger for better recognition accuracy.
