5. Maintenance
5.1 Battery Management
The alarm panel features an internal 1500 mAh backup battery, ensuring continued operation during power outages. Sensors are typically battery-powered and will indicate low battery status through the app or on the sensor itself. Replace sensor batteries promptly when indicated.
5.2 System Checks
Regularly check the status of all sensors and the alarm panel via the TUYA app to ensure they are online and functioning correctly. Test the alarm system periodically by triggering a sensor in armed mode to confirm siren activation and notification delivery.
5.3 Anti-Sabotage Function
The system is equipped with an anti-sabotage function that detects and reports attempts to tamper with the alarm panel or sensors. Ensure all components are securely mounted to prevent false alarms or system compromise.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm panel not connecting to WiFi | Incorrect WiFi password; panel too far from router; 5GHz network selected. | Verify WiFi password. Move panel closer to router. Ensure you are connecting to a 2.4GHz WiFi network. Restart router and panel. |
| Sensor not pairing | Sensor battery low; sensor out of range; not in pairing mode. | Replace sensor battery. Move sensor closer to the alarm panel. Ensure both panel and sensor are in pairing mode as per instructions. |
| No notifications received | App notifications disabled; phone not connected to internet; app not running in background. | Check app notification settings on your phone. Ensure your phone has an active internet connection. Allow the TUYA app to run in the background. |
| False alarms | Improper sensor placement; pets triggering motion sensor; loose sensor. | Review sensor placement guidelines. Adjust motion sensor sensitivity or placement to avoid pet detection. Securely mount all sensors. |
| Remote control or RFID card not working | Not paired; battery low (remote control). | Ensure the accessory is correctly paired with the alarm panel. Replace the battery in the remote control if applicable. |
