5. Instalação

Proper installation is crucial for the detector's effectiveness. Consider the type of gas you are primarily detecting:

• For heavier-than-air gases (e.g., LPG): Install the detector 0.3 to 1.0 meters (1 to 3.3 feet) above the floor.
• For lighter-than-air gases (e.g., methane, carbon monoxide): Install the detector 0.3 to 1.0 meters (1 to 3.3 feet) below the ceiling.
• General Placement: Ideally, install the device 1 to 3 meters (3.3 to 9.8 feet) away from the combustion source (e.g., stove, boiler) and in a horizontal position.
• Avoid installing near windows, doors, or ventilation openings where air currents might dilute gas concentrations.
• Evite áreas com alta umidade ou temperaturas extremas.

6. Setup (App and Wi-Fi Connection)

The PHYSEN detector connects to the Tuya or Smart Life app for smart features. Ensure your Wi-Fi network is 2.4 GHz.

1. Ligar: Plug the detector into a standard 100–240 V AC European socket. The device will begin a warm-up period of approximately 3 minutes. During this time, no gas tests can be performed.
2. Enter Wi-Fi Configuration Mode: Press and hold the "TEST" button for more than 15 seconds. The green light will flash rapidly, and "E2" will appear on the screen, indicating the device is in Wi-Fi pairing mode.
3. Abra o aplicativo: Open the Tuya Smart or Smart Life app on your smartphone.
4. Adicionar dispositivo: Click "Add Device" or the "+" icon in the app. Ensure your phone's Bluetooth is active. The app should automatically detect the device. If not, select "Gas sensor" from the list of devices.
5. Conectar ao Wi-Fi: Enter your 2.4 GHz Wi-Fi network name and password in the app, then click "Next".
6. Conclusão: Wait for the device to connect successfully. Once added, click "Done".

7. Instruções de operação

7.1. Indicadores de exibição LED

• Green Light (Normal/Standby): Indicates the detector is functioning correctly.
• Displaying Values: If flammable gas exceeds 4.0% LEL or CO exceeds 20 ppm, the display will show the detected values.
• Red Light Flashing & Alarm Sounding: Indicates that the alarm threshold has been reached.
• Yellow Light & "Err" on Display: Indicates a device fault. Please contact customer service.

7.2. Método de teste

To test the methane detection function:

1. Ensure the system has completed its 3-minute warm-up period.
2. Press the button of a lighter near the air inlet of the detector and slowly release gas (ensure the lighter flame is off).
3. When the concentration reaches the alarm threshold, the alarm will activate and continue until the gas concentration drops below the threshold.

8. Alarmes e notificações

The detector provides immediate alerts to ensure your safety:

• Alarme audível: An 85 dB alarm sounds when gas or CO levels exceed safe thresholds.
• Notificações do aplicativo: The Tuya/Smart Life app will send instant Wi-Fi notifications to your phone if an alarm is triggered. This allows you to monitor your home remotely.
• Muting Alarms: You can silence the alarm directly from the app.
• Dispositivo de compartilhamento: Share access to the device with family members for enhanced security, allowing multiple users to receive notifications and manage alarms.

Figure 7: Real-time app notifications keep you informed of any gas or CO alarms, low battery, or device faults.

Figure 8: Share the device with your family for greater security, ensuring everyone receives alerts.

8.1. Paid SMS/Call Alerts (Optional)

If your phone is consistently connected to the internet (Wi-Fi or mobile data), you will receive free app alarm notifications, which are sufficient for daily use. A paid SMS or call alert service is available through the Smart Life/Tuya app for situations where your phone may frequently be offline. This service is offered and managed exclusively by the app provider, not by PHYSEN.
