Fire power supply
Basic skills
The voltage/current signal sensor can collect the voltage and current value of the detection circuit at the same time, or only collect a certain circuit or a few channels according to actual requirements. It can be networked with the fire-fighting equipment power monitoring host, and the monitoring host can judge the status of the on-site sensor. Status, after the host computer analyzes and processes, it indicates the type of a circuit fault alarm, and sends out an audible and visual fault alarm signal.
