The fire equipment power monitoring system is a system developed by our company in accordance with the national standard GB 28184-2011, specifically designed for real-time monitoring of the power supply of fire equipment. The system includes three parts: a fire equipment power status monitor, a power monitoring extension, and voltage/current sensors. Each fire equipment power status monitor can be connected to 200 voltage/current sensors and supports up to 15 extension units. A single host can have up to 200 points, and a maximum of 800 points can be achieved through extension units. The system uses voltage/current sensors to perform real-time detection of the main and backup power supplies of fire-fighting equipment, in order to determine whether the equipment power supply is experiencing overvoltage, undervoltage, overcurrent, short circuit, open circuit, or phase loss faults. When a fault occurs, it can quickly display and record the location, type, and time of the fault on the monitor, and emit sound and light alarm signals, effectively ensuring the reliability of the fire linkage system in the event of a fire.

1. Fault alarm
1) The working status of the power supply of the monitored equipment (current, voltage, alarm information);
2) Monitor power undervoltage (≤ 80% power supply voltage) or overvoltage (>110% power supply voltage):
3) Fault alarm sound signal: manually eliminated, can be restarted when there is another alarm signal input;
4) Fault alarm light signal: yellow LED indicator light:
5) During the fault period, the normal operation of non faulty circuits is not affected.
2. Alarm record
1) Capable of recording 50000 relevant fault alarm messages:
2) Alarm type: fault time type, occurrence event, location, and description;
3) Alarm event query;
4) Printing of alarm records.
3. Operation grading
1) Daily duty class: can enter the software interface to view real-time monitoring status, eliminate alarm sounds, and query alarm records
2) Monitoring operation level: It can be used for other operations beyond information maintenance of the system itself;
3) System management level: capable of operating any functional module of the system
