A fire-fighting equipment power monitoring system is designed in accordance with the national standard "Fire Equipment Power Monitoring System." This system includes a power status monitor, power bus, communication bus, and various sensors such as current, voltage, and current/voltage signal sensors, along with intermediate modules. These components work together to continuously monitor the main and backup power supplies of fire-fighting equipment in real time, detecting issues like over-voltage, under-voltage, over-current, open circuits, short circuits, and missing power supply faults.

The system plays a crucial role by offering reliable, real-time, digitized, intelligent, and automated monitoring. It provides centralized display of the power status of all monitored equipment, ensuring that fire systems remain operational during emergencies. By doing so, it significantly enhances the reliability of the entire fire linkage system and prevents critical failures caused by power outages during fires.

The importance of such systems cannot be overstated, especially in modern large-scale buildings, public gathering places, and high-rise structures. Fire control centers manage multiple safety systems, including automatic alarms, sprinklers, emergency lighting, and more. The effectiveness of these systems depends heavily on stable power supply. If fire-fighting equipment fails due to unstable or faulty power, it could lead to serious consequences, making these monitoring systems essential for safety and compliance.

This technology is widely applied in shopping malls, stadiums, hospitals, schools, airports, train stations, tunnels, and other large commercial or public buildings. It ensures that all critical fire protection systems are always ready to respond in an emergency.

Compliance Standards:

1. GB28184-2011 "Fire Equipment Power Supply Monitoring System" – Established by the National Fire Protection Standardization Technical Committee, this standard defines the basic functions of the system and was implemented in 2012.

2. GB50116-2008 "Fire Automatic Alarm System Design Specifications" – Includes new regulations regarding fire equipment power monitoring systems.

3. Design Atlas for Fire Equipment Power Monitoring Systems – Published by the China Building Standard Design and Research Institute.

4. GB25506-2010 "General Technical Requirements for Fire Control Room" – Mandates that the fire control room must display the working status and undervoltage alarm information of each fire protection equipment's power supply.

System Composition:

The system consists of a monitoring host, repeaters, monitoring modules, and transmission cables. The monitoring host can support up to 1024 modules across 64 loops (each loop with 16 modules). Communication distance is typically limited to 500 meters, but repeaters can extend this range, managing up to 64 modules per unit.

1. Monitoring Host: Centralized and modular, it tracks, stores, and analyzes data from power supplies and fault conditions. It offers user-friendly interfaces, alarm notifications, and data reporting features, allowing efficient management and monitoring.

2. Repeater: Used when the monitoring host is far from the field modules. It extends communication range and provides power to remote modules, preventing signal and power loss over long distances.

3. Monitoring Module: Collects real-time power and equipment status data. There are three types: M1 (voltage/current monitoring), M2 (residual current monitoring), and M3 (combines both functions). These modules are rail-mounted for easy installation and maintenance.
