Water Sensor

Register the product IMEI on the cloud platform. Scan the code through the APP, or the PC management terminal of the platform, or directly input the IMEI code. Add the device to the cloud platform. Different cloud platforms have different operation modes. This task can be completed at the manufacturer during product delivery, centrally by the engineering contractors, or on-site during installation. Refer to the operation instructions of the cloud platform.
On-site installation and testing of the water immersion detector.

Open the rear cover: Hold the positive pole of the door magnet, press the rear cover with a little force, and slide the rear cover downward after misaligning it.
Insert the NB card: Press the metal piece on the NB card slot with a little force, then slide the metal piece, insert the NB card, and press and slide the metal piece again with the same force.
Start the power supply: Just remove the insulating piece on the positive pole of the battery.
The product’s self-check process. Once the power is turned on, the product immediately enters the inspection state. At this time, the red light turns on, indicating that the power is activated, and then the green light stays on, and the product enters the internal self-check process.
If the product itself is normal and the NB communication is also normal, the product will enter the NB signal strength display state. The NB signal strength is divided into four levels. If the signal is very poor, the yellow light will flash for 1 minute. If the signal strength is average, the green light will flash continuously 2 times, repeating 3 times. If the signal is good, the green light will flash continuously 3 times, repeating 3 times. If the signal strength is excellent, the green light will flash continuously 4 times, repeating 3 times. When installing the product, try to find the best NB signal point for installation. When the signal is not good, the product’s power consumption will increase significantly.
If the product finds problems during self-check, the red light will flash continuously as a reminder. One flash of the red light indicates an NB module failure. Two flashes of the red light indicate an NB card failure. Check for problems such as the card’s specification, activation, and poor contact. Three flashes of the red light indicate that the NB signal fails to connect to the operator’s base station and cannot access the Internet. Four flashes of the red light indicate a communication failure between the NB signal and the operator’s service platform, generally due to identity recognition problems.
Test the anti-disassembly switch. Trigger the anti-disassembly switch, and the red light will flash once, indicating that the anti-disassembly switch function is normal.
Test the water immersion function. Use your hand, a metal object, or water to short-circuit the metal probe for more than 1 second, and the product will flash the red light continuously. When sending an alarm signal, the green light will flash once.
After the test is completed, fix the rear cover with 3M adhesive or screws. Align the inner edge of the positive pole bottom of the door magnet with the positioning post protruding from the middle of the lower edge of the bottom shell, then close the upper cover, slide it downward to close the product, and the water immersion main unit is successfully installed. Refer to the schematic diagram. Then, fix the water immersion probe in the place where water leakage needs to be detected.
After the product is installed, the anti-disassembly switch will automatically enter the normal working mode (when the anti-disassembly switch is closed for more than 5 seconds). If an alarm is triggered, the red light will flash once, indicating that the alarm is triggered, and the green light will flash once, indicating that the NB communication is sent.
If the NB communication fails or the device loses connection with the platform, the red light will flash 3 times.
When the battery is low, it will notify the cloud platform of the low battery and prompt to replace the battery. At the same time, the green light of the door magnet will flash 3 times, and it will flash once every 1 hour.
