- Ensure the sensor's detection area covers the desired entry points or high-traffic zones.
4.2.2 Door/Window Sensors
- Install the main part of the sensor on the door or window frame and the magnetic part on the moving door or window.
- Ensure the two parts are aligned and within 1 cm (0.4 inches) of each other when the door/window is closed.
- Use the provided adhesive or screws for secure mounting.
4.2.3 Wired Siren
- Connect the wired siren to the designated siren port on the main panel.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System not arming/disarming via remote. | Remote control battery low or out of range. | Replace remote control battery. Move closer to the main panel. |
| No alarm calls/SMS received. | No SIM card, SIM card credit low, incorrect phone numbers programmed, or poor GSM signal. | Ensure SIM card is inserted and has credit. Verify programmed numbers. Check GSM signal strength on the panel. |
| False alarms from PIR sensors. | Incorrect placement (near heat sources, direct sunlight, pets) or "Normal" zone attribute for pet areas. | Relocate sensor. Change zone attribute to "Intelligent" for areas with pets. |
| Main panel not powering on. | Power adapter issue or internal battery depleted. | Check power adapter connection. Allow time for internal battery to charge. |
| Sensors not triggering alarm. | Sensor battery low, sensor out of range, or sensor not properly paired/enabled. | Replace sensor battery. Move sensor closer to panel. Re-pair sensor if necessary. Check zone attribute. |
