1. Introduction
This product is designed to detect explosive gases (natural gas and LPG) in the air for houses, offices, and similar places. In case of gas leak, it sounds an alarm with voice prompt, pushes text notifications to your mobile, and can drive a valve/manipulator to turn the gas leak source off.
It also functions as a fire alarm device with a built-in heat sensor, designed to respond when the convected thermal energy of a fire increases the temperature.
You can monitor the gas level and temperature via a mobile application from anywhere in the world. An Internet connection via a Wi-Fi 802.11 b/g/n (2.4GHz) network is required for operation. The TFT color LCD screen displays the date and time, gas level, temperature, and remaining sensor life days.

5. Installation
5.1. Important Considerations
- Do not install the detector where the temperature is under 0°C or over +55°C, or outdoors.
- Avoid installing near exhaust fans, vaporous areas, chimney hoods, or smelly places.
- The detector should not be very close to apertures and ventilation channels, as strong air currents may decrease gas concentration and affect detection accuracy.
5.2. Location Guidelines
For Natural Gas (Methane): Natural gas is lighter than air. In case of a leak, it rises towards the ceiling. Therefore, the alarm apparatus should be located 30 cm under the ceiling and 1.5-4 meters away from the gas supply.
For LPG (Propane and Butane): LPG is heavier than air. In case of a leak, it falls to the ground. Therefore, the alarm apparatus should be located 30 cm above the floor and 1.5-4 meters away from the gas supply.
5.3. Mounting Methods
You can install the detector using screws or adhesive tape:
- Using Screws: Screw the bracket to the ceiling or wall with the included screws. Hold your detector against the bracket and turn it clockwise to fix it in place.
- Using Adhesive Tape: Tear off one side of the double-sided adhesive tape and stick it to the underside of the detector. Tear off the other side and attach the detector to a flat surface.
6. App & Wi-Fi Configuration
To connect your detector to the internet and control it via your smartphone, follow these steps:
6.1. Download the App
Scan the QR code below or search for "Smart Life" in Google Play Store (for Android) or Apple App Store (for iOS) to download and install the application. Once installed, the app will guide you through registration.
6.2. Add Your Detector (Wi-Fi Version)
Ensure your Wi-Fi network is 2.4GHz. 5GHz networks are not supported.
- Smartlink (EZ) Mode:
- In the app, tap "Add Device" or "+" and select "Security & Sensors" from "Add Manually". Then, tap "Gas Detector (Wi-Fi)".
- Choose your local Wi-Fi network and input its password.
- Power off your detector. Press and hold the button, then power on the detector. Do not release the button until the screen displays "Smart Mode, Connecting".
- Tap "Fast flashing" in the app and wait for the configuration to finish. Tap to name your detector, then tap "Done".
- Soft AP Mode (if Smartlink fails):
- Power off your detector. Press and hold the button, then power on the detector. Do not release until the screen displays "Smart Mode, Connecting". Click the button again, and the screen will display "AP Mode, Connecting".
- In the app, tap the top right icon to select "AP Mode", then tap "Slow flashing".
- Tap "Confirm" > "Go to Connect", then choose the Wi-Fi hotspot named "Smartlife-XXXX" from your phone's Wi-Fi list.
- Return to the app and wait for the Wi-Fi configuration to finish.

6.3. Linked Peripherals
The detector can be connected to external equipment such as solenoid valves and exhaust fans. Upon an alarm, the equipment is automatically controlled to mitigate potential safety hazards. The middle socket on the back of the device is for a manipulator, and the right socket is for valve control.
7. Operating Instructions
7.1. Warm-up
After powering on, the detector will warm up within 180 seconds. The screen will display "Waiting" with a countdown and ticking sound.
7.2. Working Display
The screen displays the working window and clock panel alternately every minute. The Wi-Fi icon indicates connection status:
- Connected: Shown with a dot.
- Offline: Shown in gray.
- No icon: Indicates Wi-Fi module failure.
The "Life" indicator shows remaining sensor life days. If a fault occurs, it will display "Fault".
7.3. Gas Leak Alarm
When a gas leak is detected, the level ring is displayed, and "There is a gas leak. Check now" is heard. If the gas leak level continuously rises and reaches the preset level, the detector alarms sound, the red alarm indicator flashes, and you will hear "Emergency. There is a gas leak. Don't use any electrical switches and naked flames. Get out and call for help now". A notification "Gas leak detected" is pushed to your mobile, and the valve/manipulator is activated to turn the gas source off.
7.4. Heat Alarm
When the temperature around the detector increases to the preset value (57°C), the red alarm indicator flashes, the value ring is displayed, and "Heat alarm. Check now" is heard. A text notification is also pushed to your mobile.
7.5. Silence Alarm
In case of an alarm, you can click the button on the device or tap the silence icon in the APP to mute the alarm sound. The screen will then display "Alarm has been hushed" with the same voice prompt.
7.6. Restore to Normal from Alarm
The alarm is automatically canceled when the air clears and the temperature around the detector drops below the alarm setting value.
8. Maintenance
8.1. Testing the Detector
Without an active alarm, you can test the detector by clicking the button on the device or tapping the test icon in the APP. The screen will display "Ready for test" and you will hear "This is a mere test. We'll alarm a sound. The alarm is loud. The test starts". The detector will then test for low-level gas leak, high-level gas leak alarm, heat alarm, and valve/manipulator control. When the test is finished, the screen will display "Test finished. Please reset valve". If everything is OK, "The test is finished. Everything is OK" will be heard, and a text notification will be pushed to your mobile.
8.2. Clock Adjustment
The date and time are usually updated automatically over the network if your detector is connected via Wi-Fi. If not, you can adjust the date and time manually:
- Without an alarm, press and hold the button until the date and time setting window is displayed.
- The digit will increase automatically in a loop (from year). Click the button to select the digit you want to adjust, and the screen will skip to the next digit.
- Once all date and time digits are entered, they will turn green, and the screen will display "Long click to save". Press and hold the button until you hear a tone to save the settings.
- If there is no operation for 30 seconds, the detector will exit the date and time adjustment, and any unsaved digits will be lost.
9. Troubleshooting
9.1. Sensor Fault
In case of a sensor fault, the yellow fault indicator will flash, and "Fault" will be displayed on the screen. You will hear "The sensor failed. Check now", and your mobile will receive a text notification. If this occurs, please contact customer support.
9.2. Power Outage
The device requires continuous power (Micro USB+5V/1A) to operate. In the event of a power outage, the device will not function. It does not have a built-in battery for backup power. Ensure a stable power supply for continuous protection.
10. User Tips
- Regular Testing: Perform weekly tests using the device button or the app to ensure the sensor is functioning correctly.
- App Notifications: Keep app notifications enabled on your mobile device to receive immediate alerts for gas leaks or high temperatures, even when you are away from home.
- Wi-Fi Stability: Ensure a stable 2.4GHz Wi-Fi connection for reliable remote monitoring and notifications.
- Placement is Key: Carefully consider the type of gas you are detecting (natural gas or LPG) and place the detector according to the guidelines in the Installation section for optimal performance.
11. Safety Considerations and Warnings
- Vapors from alcohol, sprays, very intense cigarette smoke, torch gas, cleaning agents, chemical substances with strong odors, intense meal vapors, and water vapors may cause the alarm to malfunction by misleading the apparatus.
- This product is designed to reduce the risk of accidents but cannot guarantee absolute safety.
- Always use the detector correctly and maintain a strong awareness of safety and security in your daily life.
