High Quality Auto Sensor Glass Doors From GP Global

Today, let's talk about the opening direction of fire doors. Whether you know about fire doors or not, at least you know that it is a door. Since it is a door, there are always door leaves. When someone passes through, the door leaves must be opened, inward or outward or left or right. Otherwise, it is not a fire door but a firewall.

What are the regulations for the opening direction of fire doors? When you see this, you can look up at your own door or office door. You can see that some of them are pulled inward and some are pushed outward. Generally, they are installed in a convenient and beautiful way according to the needs. Fire doors are different. Whether they are steel fire doors or wooden fire doors, and whether you need to install Class A, Class B or Class C fire doors, their opening directions are the same, that is, the direction of personnel escape and evacuation. This is because when a fire occurs, people run out of the building. If the fire door is installed in the opposite direction, it will inevitably affect the evacuation of personnel, so our country stipulates the opening direction of fire doors.

It must be the direction of personnel escape and evacuation. How do you determine the direction of evacuation? This is very simple. If it is a room, the aisle outside the door is the direction of evacuation. No matter how many doors and rooms there are, as long as it is from the inside to the outside, the outside is the direction the door opens. If it is a staircase, except for the basement, first floor and top floor, all fire doors on the second floor and above must open in the direction of the stairs. The fire door on the first floor opens to the aisle or outside, the basement opens to the outside, and the top floor opens to the roof. As long as the fire door opens in the direction of evacuation, it will be correct.

Automatic sensor doors are famous for their convenience and sense of technology, and are widely used in various places. So, how does it work?

The main controller is the "brain" of the automatic door. It sends instructions through the internal program to control the opening and closing of the door leaf.

The induction detector is like a pair of keen eyes. When an object enters its sensing range, it will immediately send a signal to the main controller.

The power motor provides the power to open and close the door leaf, allowing the door leaf to run smoothly and powerfully.

The door leaf travel track is like a train track, ensuring that the door leaf moves in the predetermined direction.

The door leaf spreader wheel system is responsible for hanging and driving the door leaf to ensure the stability of the door leaf.

The synchronous belt or V-belt transmits power to ensure the uniform operation of the door leaf.

The lower guide system prevents the door leaf from swinging during operation and maintains the stability of the door.

When someone enters the sensing range, the sensing detector sends a signal to the main controller. After judgment, the main controller notifies the motor to run, and the door leaf will automatically open. When the person leaves, the controller will determine whether it is necessary to close the door and notify the motor to perform reverse movement.

The emergence of automatic sensor doors not only improves the intelligence level of the door, but also greatly improves the convenience of use.
