4.2 Alarm Activation and Notifications

When a detector (e.g., door sensor, PIR motion sensor) is triggered while the system is armed, the alarm will activate. The wired siren will sound loudly (over 120dB) to deter intruders and alert occupants.

Simultaneously, the system will:

• Automatically dial up to 6 preset phone numbers.
• Send SMS text messages to notify you which zone has a security breach.
• Provide a 10-second automatic message recording (if configured) to inform the recipient of the alarm location and zone.
• Send push notifications to the smartphone app.

5. Maintenance

5.1 Battery Replacement

The wireless PIR motion sensor, door sensor, and remote controls are battery-powered. It is recommended to check the battery status periodically. Replace batteries when low to ensure continuous operation. The system uses AAA batteries (included for initial setup).

5.2 General Care

Keep the alarm panel and sensors clean by wiping them with a soft, dry cloth. Avoid using abrasive cleaners or solvents. Ensure the sensors are not obstructed and have a clear line of sight for optimal performance.

6. Troubleshooting

• WiFi Connection Issues: Ensure your router is broadcasting a 2.4GHz WiFi signal. The system does not support 5GHz WiFi. Verify the WiFi password entered is correct and does not contain special characters.
• GSM SIM Card Not Working: Check if the SIM card has credit and is active. Ensure it is a standard GSM SIM card operating on the supported frequencies (850/900/1800/1900MHz).
• Sensors Not Triggering Alarm: Verify that the sensors are properly paired with the alarm panel. Check the battery levels of the sensors and replace if necessary. Ensure sensors are installed within the effective wireless range of the main panel.
• Remote Control Sensitivity: The remote control buttons can be sensitive. Exercise care when handling to avoid accidental arming or triggering of the panic function.
• Siren Not Sounding: Check the wired connection of the siren to the alarm panel. Ensure the siren is not damaged.
