**Fire Door Monitoring System: Composition, Functions, and Applications**
The fire door monitoring system is a critical component of modern building safety infrastructure. It monitors the operational status of fire doors, ensuring they function properly during emergencies to prevent the spread of fire and smoke. This system is mandated by the "Design Code for Automatic Fire Alarm Systems" (GB 50116-2013) as part of the broader automatic fire alarm system.
This article explores the structure and practical applications of the fire door monitoring system, emphasizing its vital role in safeguarding lives and property. By adhering to national standards and guidelines, the AFRD fire door monitoring system offers comprehensive solutions for monitoring fire doors, ensuring compliance and efficiency.
**Composition of the Fire Door Monitoring System**
The fire door monitoring system primarily consists of several key components:
1. **Fire Door Monitor**: Acting as the central control unit, the fire door monitor tracks the open or closed states of fire doors via sensors and actuators. It also sends alarms if doors remain in an abnormal state and can automatically close fire doors upon receiving a fire signal from the fire alarm system. The AFRD100/B fire door monitor (Figure 2) is a prime example of this technology, featuring an 8-inch touch screen and multiple communication options.
2. **Fire Door Monitoring Module**: These modules control the electromagnetic release units and electric door closers while relaying magnetic switch signals. There are two types: normally closed (closed by default) and normally open (open by default).
3. **Electric Door Closer and Electromagnetic Releaser**: Electric door closers and electromagnetic releases are essential for managing normally open fire doors. They work together to provide remote control over fire doors and feedback their statuses to the monitoring system.
4. **Magnetic Switch**: Comprising two magnets—one fixed on the door and the other on the frame—the magnetic switch detects whether a door is open or closed, sending signals back to the fire door monitor.
**Applications of the Fire Door Monitoring System**
The AFRD fire door monitoring system has been successfully deployed in various settings, including commercial buildings (Figure 6). The system’s versatility ensures compliance with national standards like GB29364-2012 and GB50116-2013, facilitating efficient fire safety management.
Key features include:
- **Bus Control Functionality**: Ensures reliable communication between modules even in the presence of faults.
- **Firefighting Linkage**: Automatically closes normally open fire doors upon detecting a fire, containing the blaze.
- **Remote Monitoring**: Regional extensions allow for long-distance monitoring and resetting of modules.
- **User-Friendly Interface**: Simple, intuitive controls make operation and maintenance straightforward.
**Conclusion**
The fire door monitoring system is indispensable for maintaining building safety. Its ability to monitor fire doors in real time helps prevent accidents and ensures swift responses in emergencies. Implementing this system in buildings not only meets regulatory requirements but also enhances overall fire safety.
