At present, it is needless to say that the country attaches great importance to fire safety. During the construction process, many fire protection products have become mandatory products. Relevant standards have also been issued for the "Fire Door Monitoring System". It can be seen that the importance of fire door monitoring equipment is self-evident, but why is it important? How important is it?
Relevant professionals pointed out that often closed monitors are often used in fire door monitoring systems. However, such people have found that some of the normally closed monitoring equipment will be in the open state, and some will not be able to be closed normally due to the damage of the sequencer, and even the fire door may be blocked by the operators of some places. Removed without permission! Was it right then? There is no doubt that normally closed products have many benefits in the closed state. They can ensure that after a fire occurs, they can effectively prevent the invasion of dense smoke and fire, thereby providing valuable time for the vegetables of the personnel. Therefore, when in the normally closed state, do not open the picture for the sake of quickness, convenience, or lock it.
Similarly, the normally closed fire door monitoring equipment will be in the fire passage and the elevator room, so it will frequently open and close the door when there is a lot of people during the frequent movement of people, and when there is a lot of traffic, so It will easily lead to personnel damage, and the hardware and electrical products will be damaged accordingly, so the situation of insufficient closing performance will occur! Maybe everyone doesn't feel deep enough, but once a fire breaks out, its smoke and fire blocking effect will be lost, so everyone needs to be careful! At present, Shenzhen Fengfan Technology has designed an electric door closer that can make the fire door in a normally open state. Once a fire occurs, it can quickly close the fire door to prevent smoke and fire.
With the fire door monitoring system (electric door closer), after the fire, the alarm can be issued as soon as possible to ensure that the personnel can escape safely and win the most precious time for the safe evacuation and rescue of the personnel, so at that moment How glad you are that fire door monitoring equipment appears in our lives. With the fire door of this system, it is undoubtedly a door for our lives. After all, once it is in a fault state, it will cause the fire to be uneconomical, and it will easily lead to a small fire becoming a large fire, a large fire becoming a small fire, or even a chimney effect, resulting in the thick smoke being unable to spread, causing safety evacuation and rescue work to be normal Operation, easy to cause serious consequences!
Therefore, the installation of this device is extremely important, it is related to the personal safety and economic loss of everyone, and it plays an effective role in protecting the safety and evacuation of personnel. May the above series of explanations on "the importance of fire door monitoring equipment be self-evident" can let everyone know an overview and an overview!
The fire door electric door closer is an electric device that can close the fire door in the opened state after receiving the instruction, and feedback the status information to the fire door monitor through the door magnetic switch, which is suitable for the control of normally open fire doors. The integrated door closer integrated module communicates with two buses. The split door closer needs to be connected to the LN9M fire door monitoring module. The electric door closer is installed on the normally open fire door, which monitors the opening and closing status of the normally open fire door in real time, and uploads the status information of the fire door to the fire door monitor. It is generally installed above the fire door. When a fire occurs, the fire door monitor issues a door closing instruction to start the electric door closer to close the fire door.
