SIWOFB fire power monitoring system, mainly for the fire equipment, the power of the parameters of real-time monitoring. By detecting the voltage, current and switch status of the power supply of the fire fighting equipment, it is judged whether there is a short circuit, an open circuit, an overvoltage, an undervoltage, an overcurrent, a phase failure, an overload and the like, and timely alarm and recording. SIWOFB fire power supply real-time monitoring system with high reliability, real-time and so on, through efficient operation and convenient communication function, real-time reflect the status of the equipment being monitored equipment, centralized display of the parameters of information, so as to effectively prevent the fire , The fire equipment due to power failure and can not work the critical situation, to maximize the protection of fire linkage system reliability.
