Functional Features：

---

Monitor single-phase voltage and current in one channel, using a non-polar two bus without the need for an external power supply, and encode using the GS701 encoder. High precision, with an error of ≤ 5%. Real time monitoring of the working status of fire equipment power supply. Real time monitoring of power overvoltage, undervoltage, phase loss, power interruption and other faults in fire equipment, and reporting of fault information to the monitor.
