Haozee Smart Gas Leakage Alarm Detector User Manual

1. Panimula

The Haozee Smart Gas Leakage Alarm Detector is a crucial safety device designed to monitor and detect the presence of various combustible gases in your home or office. It provides early warning of potential gas leaks, helping to prevent hazards such as fires and explosions. This device is available in two versions: a Wi-Fi version that operates independently and a Zigbee version that requires a Tuya Zigbee hub for functionality. Both versions integrate with smart home platforms for enhanced control and monitoring.

5. Pag-setup

5.1. Lokasyon ng Pag-install

Correct installation is critical for effective gas detection. The placement depends on whether the gas to be detected is heavier or lighter than air.

For gases heavier than air (e.g., LPG, Propane): Install the detector at 0.3-1 meter height from the floor. The semi-diameter to the gas source should be less than 1.5 meters.
For gases lighter than air (e.g., Natural Gas, Methane, Manufactured Gas, Marsh Gas): Install the detector at 0.3-1 meter height from the ceiling. The semi-diameter to the gas source should be less than 1.5 meters.

Avoid installing the detector in areas with strong air currents, near ventilation openings, or in places where it might be obstructed.

5.2. Pag-on

Plug the detector into a standard AC 85V-250V power outlet. The device will initiate a self-test sequence upon power-up.

5.3. Connecting to Smart Home System

For Wi-Fi Version:

Download the Tuya Smart or Smart Life app from your mobile app store.
Magrehistro o mag-log in sa iyong account.
Follow the in-app instructions to add a new device. The Wi-Fi version does not require a separate hub.

For Zigbee Version:

Ensure you have a Tuya Zigbee hub (gateway) already set up and connected to your smart home app.
Download the Tuya Smart or Smart Life app from your mobile app store.
Magrehistro o mag-log in sa iyong account.
Follow the in-app instructions to add a new sub-device under your Zigbee hub.

6. Mga Tagubilin sa Pagpapatakbo

6.1. Self-Test Function

The device features a self-test button on the unit itself and also within the mobile application. Pressing this button will test the alarm and buzzer functionality. The red LED will flash, and the buzzer will beep, indicating normal operation.

6.2. Alarm Behavior

When the concentration of detected gas reaches or exceeds the preset alarm threshold (e.g., 6%LEL for CH4), the detector will automatically enter a continuous alarm state. This includes a loud audible alarm and, if connected to the app, notifications to your smartphone.

6.3. Alert Handling Procedures

In the event of a gas alarm, immediately take the following actions:

Close the main gas pipeline valve immediately.
Extinguish all sources of ignition (e.g., open flames, cigarettes) and avoid using anything that generates sparks.
Do not switch any electrical appliances ON or OFF (lights, fans, etc.) as this can create sparks.
Immediately open windows and doors to ventilate the indoor air.
If the alarm persists or you suspect a significant leak, evacuate the premises and contact your gas provider or emergency services.

7. Pagpapanatili

Regular na Pagsusuri: Perform a self-test using the button on the device or through the app at least once a month to ensure proper functionality.
Paglilinis: Gently wipe the exterior of the detector with a soft, dry cloth. Do not use cleaning agents, solvents, or abrasive materials, as these can damage the sensor. Ensure the ventilation holes are free from dust and debris.
Iwasan ang Sagabal: Periodically check that nothing is blocking the detector's sensor or alarm output.

8. Pag-aayos ng solusyon

Problema	Posibleng Dahilan	Solusyon
Detector not powering on	No power to outlet; faulty unit.	Check power outlet with another device. Ensure plug is fully inserted. If still no power, contact support.
Alarm not sounding during self-test	Buzzer malfunction; internal fault.	Ensure the self-test button is pressed firmly. If no sound, the unit may be faulty; contact support.
Maling mga alarma	Interference from cooking fumes, aerosols, or improper placement.	Relocate the detector away from cooking areas, strong fumes, or high humidity. Ensure proper ventilation in the area.
Wi-Fi/Zigbee connection issues	Weak signal; incorrect setup; Zigbee hub not connected (for Zigbee version).	Ensure the detector is within range of your Wi-Fi router or Zigbee hub. Check your network connection. For Zigbee, verify the hub is online and the device is correctly paired. Reset the device and try pairing again.
Alarm sounds but no gas detected	Sensor sensitivity; residual gas; environmental factors.	Ventilate the area thoroughly. Perform a self-test. If false alarms persist, consider environmental factors or contact support.

9. Mga Tip sa Gumagamit

Know Your Gas Type: Confirm whether your household gas is heavier (LPG, propane) or lighter (natural gas, methane) than air to ensure correct installation height.
Mahalaga ang Zigbee Hub: If you purchased the Zigbee version, remember that a Tuya Zigbee hub is required for the device to function and connect to your smart home system. The Wi-Fi version does not need a separate hub.
LEL Setting: The alarm density (Lower Explosive Limit or LEL) is a pre-set value for safety and is not user-adjustable. The device is designed to trigger an alarm well before dangerous concentrations are reached.
Pagsasama ng App: Utilize the Tuya Smart or Smart Life app for remote monitoring, receiving alerts, and performing remote self-tests, adding an extra layer of security.
Consider Linkage: For Zigbee users, explore linking the detector with a compatible Wi-Fi valve manipulator for automatic gas shut-off in case of a leak, providing an advanced safety measure.
