Difference between Fire Equipment Power Monitoring System and Fire Power Supply - Musical Bird

The difference between the fire-fighting equipment power monitoring system and the fire-fighting power supply lies in the following two points:

1. The fire-fighting equipment power monitoring system is based on the national standard “Fire-fighting equipment power monitoring system”. The system consists of fire-fighting equipment power status monitor, power bus, communication bus and its connected current signal sensor, voltage signal sensor, Current/voltage signal sensor, medium-level module box and other equipments, real-time detection of the main power supply and standby power supply of the fire-fighting equipment through the sensor, so as to judge whether the power supply equipment has over-voltage, under-voltage, over-current, open-circuit, short-circuit and missing faults. . When the fault occurs, the location, type and time of the fault can be quickly displayed and recorded on the monitor, and an audible and visual alarm signal is issued, thereby effectively ensuring the reliability of the fire linkage system when the fire occurs.

2. Fire-fighting power supply is suitable for providing centralized power supply for evacuation lighting and other important first-level power supply loads when a building is in a fire. When the AC mains power is normal, AC mains supply power to important loads through mutual investment devices. After the AC mains power is cut off, the mutual investment device will immediately switch to the inverter power supply. The power supply time is determined by the capacity of the battery. When the mains voltage recovers, the emergency power supply will be restored to the mains power supply.
