5. Configuração e instalação
5.1 Escolhendo um local
Carbon monoxide is slightly lighter than air and mixes readily with air. For optimal detection, place the detector:
- In or near sleeping areas and living areas.
- On a wall, at least 5 feet (1.5 meters) from the floor, or on the ceiling.
- At least 15 feet (4.5 meters) away from fuel-burning appliances to avoid false alarms from normal combustion byproducts.
- Evite colocar sob luz solar direta, perto de saídas de ar, ventiladores ou em áreas extremamente empoeiradas, sujas ou engorduradas.
- Suitable for use in residential environments such as bedrooms, kitchens, garages, and attics. Ideal for enclosed spaces like hotels, RVs, and tents when traveling.

5.4 App Pairing (Tuya/Smart Life APP)
To enable mobile app alerts and remote monitoring, you need to pair the detector with the Tuya or Smart Life app.
- Baixar aplicativo: Download and install the "Tuya Smart" or "Smart Life" app from your smartphone's app store (Google Play Store for Android, Apple App Store for iOS).
- Registrar/Login: Open the app and register a new account or log in to an existing one.
- Adicionar dispositivo: Ensure your phone's Bluetooth is enabled. In the app, tap the "+" icon to add a new device.
- Entrar no modo de emparelhamento: On the CO detector, locate the RESET hole (usually on the underside). Use a small pin or paperclip to press and hold the RESET button until the LED light on the detector starts flashing rapidly. This indicates pairing mode.
- Conectar ao Wi-Fi: The app should automatically detect the device. Follow the on-screen prompts to connect the detector to your 2.4 GHz Wi-Fi network. Note: The detector only supports 2.4 GHz Wi-Fi.
- Customize Name/Location: Once paired, you can customize the device name (e.g., "Living Room CO Detector") and assign it to a specific room within the app for easier identification of alerts.

6. Operando o detector
6.1 Operação normal
Once installed and powered on, the detector continuously monitors carbon monoxide levels in the air. The LED indicator will typically be off or flash periodically (e.g., every 30 seconds) to indicate normal operation, depending on the specific model's design. Refer to the small instruction leaflet included with the product for exact LED behavior.
6.2 Testando o alarme
É recomendável testar o alarme semanalmente para garantir o funcionamento adequado.
- Press Test/Hush Button: Locate the "PUSH TO TEST/HUSH" button on the cover of the unit.
- Ativar alarme: Press and hold the button until the alarm sounds. The unit may continue to alarm for a few seconds after you release the button.
- Verify App Notification: If paired with the app, you should receive a notification on your smartphone indicating a test alarm.
- Troubleshoot if No Alarm: If the alarm does not sound, ensure the unit is receiving power (battery is installed correctly) and test it again. If it still fails, refer to the Troubleshooting section.

6.3 Alarm Conditions and Actions
In the event of a carbon monoxide detection:
- The alarm will sound an 85-decibel alarm.
- The LED light on the detector will flash.
- If paired, the mobile app will promptly notify you of the alarm, even if you are not at home.
Se o alarme tocar:
- Vá imediatamente para um local com ar fresco ao ar livre ou abra todas as portas e janelas para ventilar o ambiente.
- Não retorne ao local até que o alarme tenha parado e a área tenha sido completamente ventilada.
- Call your emergency services (e.g., 911 or local gas company) if you suspect a CO leak.
- Identificar e corrigir a fonte de monóxido de carbono.
