- Sensor Online Detection: An alarm will be triggered if the panel fails to detect a sensor for more than 72 hours, indicating a potential issue with the sensor or its connection.
- Wireless Sensor Low Voltage Warning: The system will alert you when a wireless sensor's battery is low, prompting you to replace it.

5. Troubleshooting
5.1 Common Issues and Solutions
- Doors and Windows Not Closed Warning: If the system is armed and a door/window sensor detects an open state, the panel will issue a warning. Ensure all entry points are secured before arming.
- Incorrect Password Entry: For security, if the wrong password is entered 5 consecutive times, the keyboard will refuse input for 90 seconds. Wait for the lockout period to expire before trying again.
- Sensor Not Responding: Check the sensor's battery level. Ensure the sensor is within the effective range of the alarm panel (200m for FSK, 100m for other technologies). Re-pair the sensor if necessary.
- No App Notifications/Remote Control: Verify the panel's Wi-Fi or 4G/GSM connection. Ensure the Tuya Smart app is running and has the necessary permissions on your mobile device.
- Panel Not Connecting to Wi-Fi: Ensure your Wi-Fi network is 2.4GHz, as the panel does not support 5GHz networks. Double-check the Wi-Fi password.
5.2 Important Compatibility Note
This 4G alarm panel is only compatible with FSK (Frequency Shift Keying) sensors. Ensure any additional sensors you purchase are FSK compatible.
