To introduce the electric control system of fire shutter door

We all know that fire shutter has a great fire protection effect. Generally, it is used to divide fire zones, and well control the partition to the fire wall and the door on the fire wall set by the building area. When it is difficult to set fire wall or fire door in the building, fire shutter door shall be used instead, and water curtain shall be used for protection at the same time.

The working principle of the fire shutter controller is not complicated. When a fire occurs, the fire shutter will be automatically lowered under the control of the fire central control system according to the preset procedures, so as to prevent the spread of fire to other areas and strive for valuable time for the implementation of fire fighting. In general, large buildings are equipped with central fire control system according to national fire law. When a fire occurs, the smoke sensor installed on the roof first receives the smoke signal and gives an alarm to the central control system. After identification, the central control system of fire protection connects the power supply of the fire shutter door in the fire area, so that the fire shutter in the fire area can go down at a certain speed.

After a period of time in the middle, the fire shutter will continue to descend until it is closed. The down speed and middle dwell time of the fire shutter door can be adjusted during installation. In some cases, the building is not equipped with a central fire control system. To learn more, please continue to follow our website.
