Product Function Description

Warm-up state

Before using the gas detector, it needs to heat its inside sensor to produce a chemical reaction to ensure its detecting stability and reliability. This state is called warm-up state. It goes into warm-up state for 3 minuets after being plugged into the power socket and the blue led blinks slowly with voice prompt during this period.

Early warning state

The detector goes into earning warning state when it detects the gas concentration is above 1500PPM(3%LEL). At this time, the detector would flash, make sound as well as push warning notification to user mobile until the gas concentration decreases.

Alarm state

When the detector detects the gas concentration is above 3500PPM(7%LEL), it would alarm. It would make sound, red led flashes and push alarm message to user. If the gas concentration keeps this high level it would keep sounding and flashing.

Silence the device

When the device is alarming, press the touch key to cancel the alarm sound or open the app –click device icon to enter its interface ---click mute (the red led would still flashes)

Share the device by multiple people

Open tuya app –click device icon to enter its interface – click / at upper right corner – choose share device – add other tuya account.

How to distinguish each device

Open app – click device icon to enter its interface --- click / at upper right corner – change device name. Then when it alarms, it would push message by the changed device name.

Frequently Asked Questions (FAQ)

Q What is the warm-up time required before the gas detector starts working?

The detector enters a warm-up state for 180 seconds (3 minutes) after being plugged into the power socket. During this time, the blue LED blinks slowly with a voice prompt while heating the internal sensor to ensure reliable and stable detection.

Q What is the correct installation height for LPG versus Natural Gas?

For LPG (liquefied petroleum gas), which is heavier than air, install the detector about 0.3 meters above the ground. For Natural Gas, which is lighter than air, install it more than 1.5 meters above the ground, within a 1.5-meter radius of the gas source.

Q What are the different alarm levels and responses of the detector?

The early warning triggers at 1500PPM (3%LEL) with flashing, sound, and mobile alerts. The full alarm activates at 3500PPM (7%LEL) with continuous sound (85dB), flashing red LED, and app alarm push notifications. The serious alarm level is reached at 5000PPM (10%LEL).

Q How can I mute or silence the alarm when it goes off?

You can cancel the alarm sound directly by pressing the touch key on the device, or by opening the mobile app, clicking the device icon, and selecting "mute". Please note that the red LED will continue flashing as long as the gas concentration remains high.

Q Can multiple users monitor the same gas detector?

Yes. Open the Tuya app, select your device to enter its interface, tap the icon at the upper right corner, choose "share device", and enter the other users' Tuya account details.

Q What do the different LED indicator colors mean?

The Blue LED indicates the warm-up phase (blinking) and standby mode (blinking every 10s). The Purple LED indicates network pairing status. The Red LED indicates an active gas warning or alarm state.
