Local alarm system

Medical area gas pressure alarm is suitable for monitoring the gas supply pressure of hospital floor, nurse station, operating room and other areas, real-time digital display of the monitored gas pressure, alarm points can be set according to the requirements of each parameter, and the over-limit alarm can be realized to ensure the normal gas supply pressure of the hospital. This type of gas pressure alarm in medical area is equipped with RS-485 communication interface, which can realize the networking between the main alarm box and the system host through the network.
