Introduction of fire hydrant anti-theft water alarm device
1. Without changing the appearance of the fire hydrant, directly replace the original 100mm water outlet stuffy cover.
2. Send the alarm information and data to the monitoring center through GPRS/CDMA.
The main function
Cover opening alarm, damage alarm, water alarm, knockdown alarm, pressure monitoring.
Monitoring principle of fire hydrant anti-theft water alarm device
1. When someone uses water at the 100mm water outlet and twists the fire hydrant anti-theft water alarm device, the tilt switch in the device deviates and turns on, triggering the alarm device, and transmitting the alarm information to the monitoring center through GPRS to achieve timely Call the police.
2. When someone uses water at the 65mm water outlet, the water pressure in the fire hydrant triggers the micro switch in the fire hydrant anti-theft water alarm device to close, and the alarm information is transmitted to the monitoring center through GPRS to realize the alarm.
3. The fire hydrant anti-theft water alarm device is equipped with bluetooth communication function, which realizes wireless maintenance through the mobile APP, and the mobile APP can check the alarm information at any time and determine the location of the fire hydrant.
Expanded application of anti-theft water alarm device
1. The fire hydrant anti-theft water alarm device is also equipped with 433MHz wireless communication function, which is used to expand the monitoring of fire pipeline pressure.
2. A 433MHz micro-power measurement and control terminal is installed in the meter well to collect the pipeline pressure, transmit the pressure data to the fire hydrant anti-theft water alarm device, and then periodically transmit it to the centralized control center through GPRS.
