  1. Overview of fire door monitoring system

  1.1. Fire door monitoring system setting necessity

  With the rapid development of economy and science and technology, the intensity of urban personnel is constantly increasing. When a fire occurs, the fire source is quickly isolated and the fire range is effectively controlled, which can create favorable conditions for the fire and the evacuation of personnel. Therefore, fireproof partitions such as fire doors are widely used in the fire protection design of construction projects. However, due to unreasonable design, improper selection, and inadequate monitoring, the fire doors cannot fully exert their isolation. Therefore, real-time monitoring and control of the working state of the fire door is an important measure to prevent the spread of fire and the spread of smoke, so the fire door monitoring system came into being.

  The fire door monitoring system is a new product in the field of fire safety. It integrates industrial computer technology, communication, anti-electromagnetic interference, digital sensor technology and industrial field bus control technology into an intelligent system, which can work on the working status of fire doors for 24 hours. Real-time automatic inspection, giving an alarm to the fire door in an abnormal state. In the event of a fire, the surveillance system automatically closes the fire door, gaining valuable time for fire rescue and evacuation.

  With the support of national mandatory regulations, the design and installation of fire doors has become an indispensable part of the construction engineering field. The market demand for fire door monitoring systems is increasing, and the market relationship is in short supply. Therefore, this system has broad market prospects and is becoming a sunrise industry in the fire protection field.

  1.2. Design basis of fire door monitoring system

  National Standard of the People's Republic of China GB29364-2012 "Fire Door Monitor"

  National Standard of the People's Republic of China GB50116-2013 "Design Specification for Automatic Fire Alarm System"

  1.3. Introduction to AFRD fire door monitoring system

  The AFRD fire door monitoring system centrally controls the working status of each terminal device, namely the electric door closer and the electromagnetic release device, and displays the opening, closing and fault status of the fire door of the evacuation channel, and displays the fault signals such as open circuit and short circuit of the terminal device in real time. The system uses the fire two bus to connect the monitoring modules with communication functions. When the terminal equipment is short-circuited or disconnected, the fire door monitor can send out an alarm signal, can indicate the alarm part and save the alarm information, which guarantees the maximum protection. Electrical safety reliability.

  The AFRD fire door monitoring system adopts centralized power supply mode, and the on-site monitoring module uses DC24V safe voltage power supply to effectively ensure the stability and safety of the system. At present, it is widely used in airports, rail transit, tunnels, passenger transportation hubs, hospitals, schools, gymnasiums, exhibition halls, star-rated hotels, high-end commercial buildings and other places.
