The fire door monitoring system consists of fire door monitors, fire door electric door closers, fire door magnetic switches, input and output interfaces, etc. Due to the fact that fire doors are divided into normally closed fire doors and normally open fire doors, different fire door monitoring systems should be configured for each type of fire door.

Firstly, we need to understand how normally open and normally closed fire doors play a role in fire prevention. Normally open fire doors are installed in places with large crowds, such as schools, large shopping malls, hospitals, etc. Due to frequent access to stairwells, it would be inconvenient to install normally closed fire doors in these places. At the same time, if people frequently open fire doors, it can cause damage to normally closed fire doors, so these places usually install normally open fire doors. The normally open fire door is in an open state under normal circumstances, making it convenient for people to enter and exit. When a fire occurs, the fire door monitor sends an alarm signal and the electric door closer closes the fire door. The normally open fire door is closed by the electric door closer. The function of an electric door closer is to automatically close a normally open fire door upon receiving a signal, while also providing feedback to the fire door monitor to inform them that the door has been closed. After receiving feedback signals, the fire door monitor will no longer sound an alarm. In this way, the normally open fire door will be closed under the action of the fire door monitoring system in the event of a fire, playing a role in smoke and fire isolation, ensuring smooth evacuation routes such as stairs. Therefore, the configuration of the frequently opened fire door monitoring system is: fire door monitor, fire door electric door closer.

Normally closed fire doors are installed in places with fewer crowds. Under normal circumstances and in the event of a fire, it should be in a closed state to prevent smoke and fire from spreading. Some people say that since they are all in a closed state, is it still necessary to install a fire door monitoring system? The answer is that installation is still required. Because normally closed fire doors cannot guarantee that they will always be in a closed state. Many fire accidents that have occurred so far have been caused by people opening normally closed fire doors, such as using fire extinguishers or bicycles to keep them open. Once the normally closed fire door is in the open state for too long, when a fire occurs, the fire is prone to spread to fire exits such as stairwells, without playing a role in fire prevention. The fireproof door magnetic switch is actually a signal device that detects the normally closed door status. Therefore, when someone opens the normally closed fireproof door for too long, the door magnetic switch will give a signal to the fireproof door monitor, and the fireproof door monitor will sound an alarm to remind people to handle it. Therefore, the configuration of the closed door fire door monitoring system is: fire door monitor, fire door magnetic switch.
