4. Maintenance
4.1 Power Supply
The alarm base station should always be connected to the AC adapter for continuous operation. The internal backup battery provides approximately 4 hours of power during outages.
4.2 Battery Replacement
Door/window sensors and key fobs are battery-powered. When a sensor's battery is low, the app will typically indicate its status. Replace batteries promptly to ensure continuous protection. Refer to the individual sensor/fob for specific battery types (e.g., CR2032 coin cell for many small sensors).
4.3 Cleaning
Wipe the devices with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the surfaces or internal components.
5. Troubleshooting
5.1 Connectivity Issues
- Cannot connect to WiFi: Ensure your router is broadcasting a 2.4GHz network. The system does not support 5GHz WiFi. Verify your WiFi password is correct.
- Device offline in app: Check if the alarm base station is powered on and connected to AC. Verify your home WiFi network is active and stable.
5.2 Sensors Not Triggering
- Check sensor alignment: Ensure the two parts of the door/window sensor are within 0.3 inches when closed.
- Verify sensor battery: Replace batteries if they are low or depleted.
- Check app status: Ensure the specific sensor is enabled and the system is in an armed mode.
5.3 False Alarms
- Review sensor placement: Ensure sensors are securely mounted and not subject to accidental triggers (e.g., loose doors, strong vibrations).
- Check app history: The app's history records can help identify which sensor triggered the alarm.
5.4 No Alarm Sound from Base Station
- Check volume settings: Ensure the alarm volume is not set to 'Mute' or a very low level in the app settings.
- Verify alarm mode: Confirm the system is in an armed state that allows for audible alarms.
