Technical Specifications
Attention:
1. After the product is plugged in, wait for 180 seconds and it will automatically turn on the normal working state, wait for 30 minutes and the product will enter the stable working state.
2. The product has a self-test button, after receiving the product, you can first plug in the self-test of the product status, that is, press the self-test button after the product alarm sounded, while the product on the green, red and yellow indicators will light up at the same time, check the alarm sound and the three colors of the indicator are normal. After the alarm stops, the product will automatically return to its normal working state, i.e. only the green indicator light is on.
3. The gas test concentration unit ranges from 0-10% LEL. When gas concentration reaches or exceeds 3% LEL, the display shows the concentration level. When gas concentration reaches or exceeds 5% LEL, an audible alarm sounds.
4. If detection remains unsuccessful, unplug the device and wipe it clean with a paper towel, as dust accumulation can also cause inaccurate readings.
5. Horizontal coverage radius: usually 5-10 meters (to the center of the alarm, open and unobstructed area). If there are walls, partitions and other obstructions in the space, the coverage area will be divided, need to be installed in each separate space.
Vertical coverage height: can only cover the same floor, can not effectively monitor across floors (such as the first floor alarm can not cover the second floor), different floors need to be installed separately.
