Installation tips

Refer to the following prohibited locations before installing the detector:

• A. Avoid installing in places where there is a lot of oil smoke, corners, cabinets and other places where the air is not easy to circulate;
• B. Can not be too close to the gas stove, avoid high temperature and high humidity environment, such as places with a lot of water vapor;
• C. Avoid large airflow in the detection area, such as near the exhaust fan;
• D. Avoid installing in direct sunlight or locations with strong electromagnetic interference.

Refer to the following prohibited installation times before installing the detector:

• A. Installation is prohibited when the house has not been painted and renovated, or the house has been renovated and the overall ventilation is less than 5 days. Please follow the schematic diagram recommended in the manual for installation. Try to find the best installation location and ensure that the product is in the effective monitoring range; during decoration, do not remove the product blister cover; open doors and windows to maintain indoor ventilation.
  If possible, the detector can be temporarily removed, otherwise the effect of the gas released in the room decoration on the detector is destructive and cannot be recovered, which may lead to false alarms or failure of the product.

• B. It is forbidden to install wood furniture in the house, or purchase new wood furniture, when its comprehensive ventilation is less than 3 days;

• C. Use or spray: insecticides (mosquitoes, cockroaches, etc.), air cleaners, glue, hairspray, etc., and installation is prohibited if the overall ventilation is less than 4 hours. Avoid contacting the detector with silicone vapor, formaldehyde, toluene, acetic acid, and hydrogen sulfide. They are mainly produced in home decoration and horizontal materials, such as: adhesives, wall coatings, hairspray, silicone rubber, etc. These can cause sensor poisoning, irrecover able damage, and cause detector false alarms or failures. High concentrations of alcohol vapor will cause false alarms; and long-term exposure to these gases will cause the detector sensitivity to drift and cannot be recovered.

Operation and adjustment

1. Self-check status：
   Turn on the power of the detector, the green indicator light flashes, and the detector enters the preheating state, which lasts for 30 seconds in the shortest time and 10 minutes in the longest time; The indicator light is always on, the preheating is over, and the detector enters the normal monitoring working state. If the status does not match the above, it needs to be returned to the factory for processing.
   Note: The gas sensor of the detector is not stable at the beginning of power-on. In order to ensure the accurate detection of the detector, it is very important to preheat the gas sensor. During the warm-up period, it is forbidden to perform a gas test on the detector. The detector does not respond to key processing and alarm events.

2. Sensitivity optional：
   Open the product shell and adjust the sensitivity through the jump cap, which is divided into three levels of L/M/H (low, normal, and high), the jump cap is inserted with “L” jump cap, it is low sensitivity; plug in “M” Jumping cap, for normal sensitivity (factory default); plug in “H” jumping cap, for high sensitivity.

3. Normal work：
   The detector continuously collects, analyzes and judges the air in the use environment. If the gas leakage reaches the alarm concentration of the detector, the buzzer of the detector will emit an alarm sound of “di~di~di~”, and the red indicator light will flash quickly and an alarm message will be issued.When an alarm occurs, press the “self-check/silence” button , the detector will enter the silencing state, the buzzer will stop beeping, but the red indicator light still keeps flashing, indicating that there is still an alarm. If the alarm is lifted at this time, the red indicator light will go out and enter the normal monitoring state.

4. Test operation:
   When the detector is monitoring normally, short press the “self test/silence” button, the detector will emit a loud “di~di~di~” alarm tone, and the red and yellow indicator lights will flash rapidly at the same time.

5. Indicator light and buzzer indication information :

   The red and yellow indicator lights are flashing, accompanied by the rapid alarm sound of the buzzer “Di~Di~Di~”| Short press the “self-test/- silence” button

6. Record reading:
   Use the special reading device specified by the national standard, and insert the connecting line on the main board (the cover needs to be opened) to the 4P pin terminal with G\U\T\R silk screen printed on it to read all the history currently stored by the detector. Record. The reading device can provide the detector’s alarm, self-test status, and information review functions.

7. Solving the internal fault of the detector：
   When encountering an internal failure of the detector, please turn off the power first, then reconnect the power, and the detector will enter the self checking state. If the fault is still not resolved, please contact the dealer in time.

Ventilation/replacement of gas sensors
8. Network function operation:

1. Pair Zigbee gateway:
   Open the Tuya APP, select the Zigbee gateway, click to add a sub-device, then, long press the “self-check/silence” button for 5 seconds, the green LED indicator flashes continuously, the device resets, and automatically sends a network access request to the Zigbee gateway. After the Zigbee gateway confirms, You can complete the network access, and prompt the device to add successfully on the APP.
   The longest configuration time is 2 minutes. If it times out, it will automatically exit the pairing mode;

2. Test function:
   When the detector is under normal monitoring, short press the “self check/silence” button, if the network alarm information is received, it means that the communication between the gas and the network platform is normal. The same operation, but does not match the above phenomenon, the test fails. Indicates that the product has not been paired (needs to be paired again) or the network communication has failed.

Product testing

After the gas leak detector is installed, power on, and the test can be performed after the self-test preheating is completed. Press the test button to enter the test mode.

Use a lighter test, the test method is as follows:
Do not use a lighter to directly jet the detector, which will cause damage to the detector. The correct way is: find a transparent plastic bag, fill it with a proper amount of air first, then use a lighter to inject into the bag without ignition for about 5 seconds, stop the injection, shake well, and then put the detector into the plastic bag. The detector should alarm immediately, and the detector should be taken out immediately after the alarm.
