How Do Automatic Sliding Doors Work

How Automatic Sliding Doors Work

Automatic electric sliding doors have quickly become the standard way for individuals to gain entrance to a building. But, even so, very few stop to think about the inner mechanics allowing these pieces of technology to function. This is how automatic sliding door mechanisms work.

Main Door Essentials

Before we can get into the specifics of how automatic sliding doors mechanisms open and close, it’s important to understand some of their fundamental parts. While there are certainly more pieces to an automatic door than can be listed here, a few of them are absolutely necessary to know. These are the main parts to keep in mind:

Door Panels

For starters, every electric sliding door consists of a series of panels. Two of these window panes will remain fixed to the outer edges of the entryway, while two other sections will make up the movable portion of the door. As the doors open, the moving windows will slide over the fixed models and create an obstruction-free space for individuals to enter.

Tracks and Rollers

Tracks and rollers, on the other hand, are what allow the automatic door mechanism to move. Positioned above and below the entryway, these components push and pull the door panels open or closed. This requires an electric signal to be fed to the belts surrounding the rollers, which causes them to slide across the track, carrying the moving door panels with them.

Motor Mechanism

The motor mechanism is what stores electricity and appropriately distributes it to the belts that help move the electric sliding doors. They’re connected by an auxiliary drive which helps control the amount of energy being exerted on the belt.

Optical Sensors

Then, lastly, the optical sensor is what tells the automatic sliding door mechanism to release that energy. As an individual approaches the door, the optical sensor, or motion detector, will notice them and activate the motor. These sensors can also be installed in the form of pressure plates depending on the type of door your building uses.

The Movement of an Automatic Door

In order to fully understand how automatic sliding doors work, you need to know how all these different components function together. When movement is picked up by the sensors, the motor mechanism is triggered to start moving its belt. This will cause the rollers to move along the tracks and pull the doors open. Once the signal from the sensor is gone, the motor will turn off and the rollers will slowly return to their former position. Keep in mind, this process might vary depending on the type of door you have installed, and your automatic door mechanism may use additional components to accomplish the same effect.

Automatic sliding doors offer convenience and efficiency for building owners and maintenance managers. Understanding the terminology associated with these doors can help in making informed decisions about installation, maintenance, and repairs. This glossary of automatic sliding door terminology will help you understand what to expect and how to manage these systems effectively. 1. Automatic Sliding Door An automatic sliding door operates without the need for manual intervention. These doors open and close in response to detected movement, offering seamless access for pedestrians. They’re commonly found in commercial buildings, such as shopping malls, airports, and office complexes, providing convenience and improved energy efficiency. 2. Motion Sensor Motion sensors play a crucial role in the operation of automatic sliding doors. These devices detect the presence of individuals approaching the door and trigger the opening mechanism. There are various types of motion sensors, including infrared sensors, microwave sensors, and photoelectric sensors. Each type has unique advantages relevant to the application and environment. 3. Activation Device An activation device is any tool or technology that initiates the opening of an automatic sliding door. While motion sensors are common, other activation devices include push buttons, key fobs, and swipe cards. Building owners and maintenance managers should choose the right activation device based on accessibility needs and expected foot traffic. 4. Door Operator The door operator is the heart of the automatic sliding door system. This motorized mechanism controls the movement of the door panels. High-quality door operators ensure smooth and reliable operation, minimizing wear and tear on the door components. Regular maintenance of the door operator is crucial to prevent unexpected breakdowns and maintain safety. 5. Safety Sensor Safety sensors are an essential feature of automatic sliding doors. They prevent the doors from closing on individuals or objects by detecting any obstruction in the door's path. If something triggers the safety sensor, the door will reverse or halt its movement. These sensors protect users and comply with safety regulations, making them a vital component of the door system. 6. Automatic Door Repair Despite the advanced technology of automatic sliding doors, they can still experience issues. Regular maintenance and prompt automatic door repair can help prolong the lifespan of the doors and maintain their efficient operation. Building owners and maintenance managers should develop a proactive maintenance schedule to address potential problems before they escalate into costly repairs. This glossary of automatic sliding door terminology provides a foundation for discussing installation, maintenance, and repairs related to automatic sliding doors. By familiarizing yourself with these terms, you can ensure smooth operation and address any issues that may arise. Embracing this knowledge will lead to a safer and more efficient environment for all building occupants. As always, reach out to Pacific Entrance today for commercial automatic door repair service.
