How do Automatic Doors Work?

30 March, 2023

Keen to learn how do automatic doors work? The automatic door maintenance and repair experts at Safetell explain…

Automatic swing doors add convenience and accessibility to a building. With automatic doors, people do not need to push or pull the door open, which can be especially useful for people with mobility impairments or those who have their hands full with bags, strollers, or other items.

This convenience can improve the overall experience of visitors and customers, and also helps to reduce the spread of germs and viruses by reducing the need for people to touch the door handle.


How do automatic doors work?

Automatic doors work by using a motor-driven mechanism to open and close the door automatically. This type of door is typically equipped with sensors that detect the presence of a person or object and then activate the motor to open the door. The door remains open for a pre-determined amount of time and then closes automatically.


Sensor Operation

The operation of the doors will usually be controlled by a variety of sensors, including infrared sensors, pressure sensors, and radar sensors. In some installations, doors may also feature a push button or touchless activation operator.

Infrared sensors detect the presence of a person or object by detecting infrared radiation emitted from the person or object. When the sensor detects the presence of a person or object, it sends a signal to the door operator to open the door.

Pressure sensors detect pressure changes in the air, and activate the door operator when a person or object comes into close proximity to the door. This type of sensor is often used in areas where a hands-free operation is desired, such as hospitals and other public buildings.


Door Operators

Automatic swing doors are operated by a motor-driven mechanism known as a door operator. There are several types of door operators that are commonly used, each with its own set of features and benefits. These include hydraulic operators, pneumatic operators, electro-mechanical operators, electro-hydraulic operators, magnetic operators and belt drive operators.

The basic operation of a door operator involves the use of a motor that drives a gear mechanism. The gear mechanism is connected to the door and rotates it on its hinges, causing the door to open or close. The speed and force of the door’s movement can be adjusted to meet the specific needs of each application.


Control Systems

Control systems are an important component of door operators, as they provide the means to control and monitor the operation of the door. The control system typically includes a control panel, which is used to adjust the settings of the door operator, such as the speed and force of the door’s movement.

The control system will be connected to the sensors and may also include safety features, such as sensors that detect obstacles in the path of the door, and stop the door from closing if an obstacle is detected. The control system may also include features that allow for the remote monitoring and control of the door.
