Basic functions

The electrical fire monitoring detector can realize real-time monitoring and collection of the residual current and temperature value of the controlled circuit, and will send out an audible and visual fault alarm signal when the fault alarm data of the detection circuit is collected; it can also be networked with the electrical fire monitoring host, and the monitoring host can judge The state of the on-site detector, the host computer analyzes and processes to indicate the type of a circuit fault alarm, and sends out an audible and visual fault alarm signal.
