MD-S271 series wireless smart fire hydrant terminal is a smart terminal with wireless transmission function developed to solve the application scenario of fire hydrant safety.
This series of products is powered by a built-in lithium battery, with ultra-low power consumption design and a battery life of up to 5 years. This series has a built-in wireless transmission module and has a variety of wireless transmission methods, including 4G/LORa/NB-iot.
The patented shell is designed to withstand 300kg strong external impact, and has passed the IP68 waterproof level certification and low temperature resistance test. The unique anti-freezing design can ensure that it still works normally in the harsh outdoor environment below -30℃. This series of products has various functions such as high and low pressure alarm, fluctuating pressure alarm, anti-tilt, GPS positioning, low battery alarm, etc., to ensure that the fire hydrant “has water available and sufficient water pressure” at critical times. This fire hydrant intelligent terminal has a variety of installation methods, supports flange installation, and is equipped with installation accessories such as installation flanges, hydraulic pipes, and installation brackets to ensure the portability of on-site installation.
At the same time, it also supports installation in the fire hydrant well, and the optional split installation structure can be easily installed in the fire hydrant well.
