- Peel off the adhesive backing and firmly press the sensor onto a clean, dry surface.
- Door/Window Contact Sensor:
- Mount the two parts of the sensor on the door/window frame and the door/window itself, ensuring they are aligned and within 1 cm (0.4 inches) of each other when the door/window is closed.
- Peel off the adhesive backing and firmly press both parts onto clean, dry surfaces.
- Siren:
- Connect the wired siren to the main panel's siren port.
- Place the siren in a location where its sound can be clearly heard throughout the property.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System not connecting to Wi-Fi. | Incorrect Wi-Fi password, 5GHz network, or weak signal. | Ensure correct 2.4GHz Wi-Fi password. Move panel closer to router. Check router settings. |
| Sensors not triggering alarm. | Low sensor battery, sensor out of range, or incorrect zone settings. | Check sensor battery status. Ensure sensor is within 50m (urban) or 150m (open field) of panel. Verify zone settings in app. |
| No app notifications. | App permissions not granted, internet connection issue, or notification settings disabled. | Check app notification permissions on your phone. Verify panel's internet connection. Ensure notifications are enabled in the app. |
| False alarms. | Improper sensor placement, environmental factors (pets, drafts), or sensitive settings. | Adjust PIR sensitivity. Reposition sensors away from heat sources or direct drafts. Use "Child Safe Mode" for specific zones if needed. |
| Main panel not responding. | Power issue, system crash. | Check power connection. If unresponsive, perform a soft reset by unplugging and replugging the power adapter. |
