3. System Components
3.1 Alarm Host (Siren)
The alarm host serves as the central unit of your security system. It connects to your Wi-Fi network, emits a loud siren when triggered, and sends notifications to your mobile application. It features a built-in backup battery for continuous operation during power outages.

3.2 Door/Window Sensors
These two-part sensors detect when a door or window is opened. When the two parts separate by more than 1 cm, an alarm is triggered, and a notification is sent to your phone.
3.3 Motion Detectors
Motion detectors use infrared technology to sense movement within their detection range. They are ideal for securing larger areas or entry points.

3.4 Remote Controls
The remote controls allow for convenient arming, disarming, and an emergency SOS function with a single press.

- Door/Window Sensors & Motion Detectors: These accessories are battery-powered. When the battery is low, the app will notify you. Replace batteries with the specified type (e.g., CR2032 for sensors, AA for motion detectors, refer to individual sensor manuals for exact type).
- Remote Controls: These also use small button-cell batteries. Replace when the indicator light fails to illuminate or range decreases.
6.2 Cleaning
Wipe all components with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials.
7. Troubleshooting
- Alarm Host not connecting to Wi-Fi:
Ensure your Wi-Fi network is 2.4 GHz. Check Wi-Fi password. Move the host closer to the router. Restart the host and your router. - Sensors not triggering alarm:
Check sensor battery levels in the app. Ensure sensors are properly paired. For door/window sensors, verify the two parts are aligned and separate by more than 1 cm when opened. For motion detectors, ensure no obstructions are blocking its field of view. - No app notifications:
Check your phone's notification settings for the Smart Life/Tuya Smart app. Ensure the app has permission to send notifications. Verify your phone has an active internet connection. - Siren not sounding:
Ensure the alarm host is powered on and connected. Check the volume settings in the app.
