Fire door monitoring system plays an important role in fire doors, especially in the event of fire, fire doors can stop the spread of fire, leaving more time for people to escape, then the various components of the fire door monitoring system can be controlled at any time The open and close state of the fire door enables the normally closed fire door to open automatically in the event of a fire. The normally open fire door automatically closes in the event of a fire. The fire door monitoring system is an LN9D fire door electric door closer and the LN9K fire door door magneto Switch, LN9F fire door electromagnetic release, LN9M fire door monitoring module, LN9H fire door monitoring host and LN9P fire door zone extension, then we look at the detailed description of the various components of the fire door monitoring system 
1. It is impossible for people to close the door when a fire occurs. Therefore, the fire door must be automatically closed and an LN9D fire door electric door closer must be provided. At present, the automatic door closers are classified into two types: hydraulic type and spring type. The hydraulic door top springs and single-tube spring hinges that are used for fire doors are mostly one-way open. It should be noted that do not mistakenly install such automatic door closers on the side of the fire surface to avoid high temperature damage in the event of a fire. It is necessary to ensure that the automatic door closer is sensitive and effective at ordinary times, and should be replaced in time if it is damaged.
2. Fire doors, which are normally open, must be provided with fixed devices to facilitate passage. Generally equipped with LN9F fire door electromagnetic release switch or fusible alloy to fix the door on both sides of the wall, in case of fire, loss of power (or energization of magnetic and latch the tongue) or burning alloy, the door is under the action of the spring Automatically closed. It is worth noting that the fire doors cannot be fixed by hooks or door cards because people who are in a panic during a fire will not close the doors. This will result in the intrusion of fireworks, thus losing the safety evacuation effect of the walkways and stairwells. .
3. Fire doors for stairwells that are specially designed for evacuation are usually locked in order to prevent theft during use. In order to solve the problem of both fire prevention and anti-theft, such fire doors can be used LN9K fire door magnetic switch, electromagnetic door locks . The staff of the building can use the key to open and enter. In the event of a fire, the circuit is connected through the remote control of the smoke detector or the fire control room. The bolt is retracted under the magnetic force and the door can be pushed open. It is also possible to set up a simple mechanical push bar door lock, which can be opened at any time by simply pushing a door inside. When a person goes out, the door will spring back and close. When entering from the outside, the key must be used to open the door. This prevents the perpetrator from entering the building.
4. Some double fire doors have a bite to seal. If they are closed in reverse order, they cannot be closed. Therefore, the sequencer that controls the steps before and after closing the door leaf must be set.
5. If the door handle of the fire door must be turned by hand to open it, it may not be able to open the door because it was burned hot in the event of a fire. For this purpose, push-type door locks should be used. The fire door can be opened only by pushing or squeezing.
6. To prevent the carpet or indoor furnishings from catching fire doors, ensure that they can be used normally in the event of a fire.
7. The fire door monitoring host LN9H is specially used for the real-time monitoring of the fire door. Real-time detection of the fire door is performed through the sensor to determine whether the fire door is purely faulty. When the fire occurs, the fire door can be quickly controlled on the monitor to isolate the fire zone. Sound and light alarm signals are also issued to effectively protect the area without fire.
8. The fire door area extension LN9P meets the requirements of the national standard GB29364-2012 “fire door monitor†24V power supply relay; can provide effective power supply for the local area partition; upload its own working status, facilitate the unified management of the LN9H fire door monitor , Extend the power supply distance of the fire door monitor to the sensor, ensure the system power supply is stable and reliable, extend the communication distance of the LN9H fire protection monitor and expand the number of management sensors, and form a more complete and stable monitoring network. The built-in backup power supply can work 8H. The standby power supply is automatically switched, which effectively ensures the reliable operation of the system. The airframe is small and flexible and easy to install.
9. The fire door monitoring module LN9M is a control device that displays and controls the fire door opening and closing state. It is also the central control room or fire automatic alarm system to connect the front electric door closer, electromagnetic door stopper, electromagnetic release device, escape door lock, etc. The bridges and ties of the device. The LN9M fire door monitoring module is suitable for normally open fire door systems with electronic control devices, electric door closers, electric releasers, and electromagnetic door stoppers. The monitor can record various states of the fire door and transmit it to the central control room for feedback to the FAS. At the same time, it can receive fire control commands from the central control room through the communication bus, and can also receive fire protection from the FAS through the monitor's fire input port. signal. When the fire command or signal is received, the monitor releases the electric control device, which is the normally closed fire door, and the purpose of isolating the fire source and preventing crosstalk.
Each product in the fire door monitoring system can also be purchased separately. It is a constantly innovative and improved product of Le Bird . Due to the market demand, the Leightard fire door monitoring system has been recruited to the country.
