At present, fire smoke exhaust windows on the market can be mainly divided into two types, one is called electric fire smoke exhaust window system, and the other is electric ventilation window system. The difference between the two is that one needs to meet fire protection requirements and achieve fire synchronization function, while the electric ventilation window system only needs to achieve normal opening and closing of the electric window. Implement ventilation function within the space. The following will introduce the fire linkage function of the electric fire smoke exhaust window system.
① Fire alarm status
When a fire occurs, the intelligent control box receives the fire signal from the original fire center of the building and transmits the signal to the window opener. After receiving the fire signal, the window opener automatically opens the fire smoke exhaust window to achieve the purpose of ventilation and smoke exhaust. It is also possible that when a fire occurs, the original fire control center of the building did not provide a fire alarm signal. In this case, you can directly break the non damaging glass on the emergency button switch panel and press the alarm button. After receiving the alarm signal from the emergency button, the fire control box will also open all the opening windows to exhaust smoke.
If a fire occurs without an external power source and the fire linkage function needs to be achieved, the existing fire control center of the building needs to provide 220V fire power to the fire control box to achieve the function of fire smoke exhaust windows.
Note: The original fire control center of the building must be equipped with backup power supply. (Implement fire linkage function)
② Daily ventilation status
The manual switch is connected to the intelligent control box. It is possible to partition and uniformly open/close the smoke exhaust windows within the partition to meet daily ventilation requirements, and the opening angle of the smoke exhaust windows can be controlled arbitrarily.
