- Sensors: PIR motion sensors and door/window contact sensors are battery-powered. When a sensor's battery is low, the system will typically notify you via the control panel or app. Replace batteries promptly to ensure continuous protection. Refer to the specific sensor's manual for battery type and replacement instructions.
6.2 Cleaning
Wipe the control panel and sensors with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the surfaces or electronic components.
7. Troubleshooting
7.1 General Issues
- System not responding: Check if the control panel is powered on and connected to a power source. Verify the power switch is in the ON position.
- Sensors not triggering: Ensure sensors are correctly installed and within range of the control panel. Check sensor batteries and replace if necessary.
- False alarms: Review sensor placement to avoid areas with drafts, direct sunlight, or pets that might trigger motion sensors. Adjust sensitivity settings if available.
