Audited Supplier The GDA-TW combustible gas detector (LoRaWAN) is a high stability combustible gas detector (hereinafter referred to as the detector), which is used to detect the leakage of combustible gas. The detector adopts advanced semiconductor gas sensor, which has stable operation, long service life and simple installation. The detector has a built-in MCU for central control processing, and each functional block is directly or indirectly connected to the I/0 port line of the MCU. The normal work of each functional module of the detector is completed through the program solidifed in the MCU, so that the detector works more stable, safe and reliable. This product is suitable for safety monitoring in places where combustible gas exists, such as family residences, real estate villas, hotels and apartments.
1. High reliability sensor;
2. Automatic reset;
3. Adopt microprocessor control;
4. Automatic fault detection indication;
5. Detection of natural gas, liquefied petroleum gas, etc.;
6. Active upload/two-way transmission function:The data will be actively uploaded to the corresponding platform through the LoRaWAN network when alarm occurs. Upload normal information every 24 hours(settable). Real time response to instructions issued by the platform.

Installation and wiring
• When detecting gases heavier than air: install 0.3-1.0 meters above the ground and within 1.5 meters of the radius of the gas source;
• When detecting gases lighter than air: install 0.3-1.0 meters below the ceiling and within 1.5 meters of the radius of the gas source (see the right figure for details);
• Fix the detector on the socket on the wall and hang the detector;
• When installing at home, you should also pay attention to the fact
that the installation location should not be too close to the gas stove;
• To prevent the detector from being baked by the flame of the stove; it cannot be installed in a place with a lot of oily smoke, so as not to cause false alarms or cause the air inlet of the detector to be blocked, which will affect the sensitivity of the detector. It also cannot be installed in exhaust fans, doors and windows, and places where there is a lot of moisture in the bathroom;
• Correct wiring according to the diagram, and all wiring installations must comply with national and local effective regulations and standards. The thickness of the wire core should be appropriate, and the wires connecting the detector and other auxiliary devices should be marked with colors to avoid wrong wiring. Improper connections will result in the product not functioning properly.
