What Is An Automatic Door?

An automatic door is an electrically powered door system, designed to automatically open for pedestrians approaching the door, and automatically close behind pedestrians after they have passed through the door. Automatic doors come in a variety of configurations with the most popular types being automatic sliding doors and automatic swinging doors.

Benefits Of Automatic Doors

Automatic doors have many advantages that make it the best choice for commercial building entrance and exit doors.

Hands Free Operation

Traditional manual entrance doors require the pedestrian to pull the door open by hand. Although this may not be a big deal to most, it can be an issue for a disabled pedestrian in a wheelchair. ADA, or the Americans With Disabilities Act specifies that manual swinging doors must be able to open with less than 5 pounds of open force for interior doors and the industry standard is less than 8.5 pounds of open force for exterior doors. Still, however, in order for a person in a wheelchair to enter the commercial building, he must roll up to the door, pull it open by reaching up to the handle, and then simultaneously use his other hand to roll his wheelchair back. This is where the convenience and ease of a commercial automatic door system comes into play. With an automatic sliding system, all pedestrians can activate the door to open by the motion sensor. With an automatic swing door system, the simple press of a handicap door opener push button, will active the door to swing open.

Adaptability To Traffic

Automatic doors excel as main entrance doors to a commercial building. Many buildings experience "rush hours" or times of the day where foot traffic entering their building is high. With traditional manual doors, each pedestrian must open the door by hand, impeding the high flow of traffic. With automatic sliding doors, however, the motion sensor will keep the doors in the full open position to allow all traffic to flow through the door opening. Both automatic sliding doors and automatic swing doors have a hold open function built into the selector switch. When activated to hold open mode, the automatic doors will remain open, until the user switches the automatic doors back to the normal mode function.

Reduce The Spread Of Germs

Did you know your hand can have over 100,000 to a few million germs on it at any given time. Did you also know that 80 percent of infectious diseases are spread by simply not washing your hands. Now with most entrance doors in commercial buildings being manual doors, customers, employees, children, and pedestrians are forced to enter the door by pulling on the door handle. The simple act of touching the door handle can not only spread your own germs on to the door handle, but also allow you to receive other pedestrian's germs that were on the door handle. The reduction and spread of germs can greatly be mitigated through the installation of automatic doors. Automatic sliding doors feature motion activated and presence detection sensors allowing absolutely zero touch for activation from any pedestrian. Likewise, automatic swing doors can be ordered with wave to open touchless activation switches, allowing a pedestrian to simply wave his or her hand in front of the activation switch to open the door.


Automatic doors come standard with a two point mechanical deadlock system which allow the doors to be secure at night. Other mechanical features such as interlocking door panels allow automatic sliding doors to be secure even further. Since automatic doors use a microprocessor control system, they can easily be integrated with any security access control system or fire alarm system, making them extremely safe and secure.

Energy Savings

Unlike most misconceptions, automatic doors can save building owners thousands of dollars in energy bills. Automatic doors are designed to open for all pedestrians and close immediately behind them, conserving the building's energy.

Automatic Door Installation Type

Exterior Automatic Doors

Commercial buildings use automatic doors as a main entrance for a commercial building. In this case, the automatic door acts as an exterior door, separating the inside of the building from the outside. Automatic doors are designed to mount in all standard construction exterior wall types including: brick, masonry, CMU, wood stud, or metal stud. Depending on the exterior wall material will determine what type of anchors are used to mount the automatic door frame to the exterior wall. For instance wood screws would be used for automatic door installation on a wood stud perimeter wall. While masonry anchor bolts would be used on a CMU wall type. The exterior automatic door frame is designed to butt against the exterior wall.

Interior Automatic Door

Interior automatic doors are gaining more popularity, especially when used as a means of separating the inside of two parts of a building. Most interior wall construction is wood stud or metal stud. The interior automatic door frame is designed to butt against the interior wall.

Automatic Door Applications

Automatic doors are ideal for any type of commercial, industrial, or institutional application.

Available Automatic Door Types

Automatic Sliding Doors

An automatic sliding door is a type of automatic door system where the doors electrically slide open, in order to allow pedestrians access through the door way. The automatic sliding door system consists of the door panels, door jambs, and top header. The automatic sliding door header houses the DC motor drive unit, control assembly, belt, and door carriage rollers. Automatic sliding doors are activated through the use of motion sensors. Additional safety presence sensors are installed on automatic sliding doors.

Automatic Swinging Doors

An automatic swinging door is a type of automatic door where the doors swing open electrically for pedestrian access. An automatic swing door consists of the door panels, door jambs, and automatic door header. The automatic door header houses a DC motor drive unit, a heavy duty gearbox with a built in spring, a control system, and an arm mechanism. Push to open or wave to open activation switches are used to activate the automatic swing door.

Automatic Door Openers

An automatic door opener is motorized electric opening and closing device only, without any doors or frame. Automatic door openers are designed to retrofit to existing commercial manual swing doors and transform them into automatic swinging doors.

Frequently Asked Questions

What Are Automatic Doors Called?

Automatic doors are named by the door type. For instance an automatic door that slides open is called an automatic sliding door system. While an automated door that swings open is called an automatic swing door system.

How Do Automatic Doors Work?

Automatic doors are electrically powered by 110VAC input. The AC voltage is converted to DC through the internal automatic door power supply. The automatic door controller outputs the DC voltage to a DC motor drive system, allowing the door to power open. Electrically powered motion sensors or SPDT activation switches are used to activate the automatic door.

How Do You Adjust An Automatic Door?

Automatic doors, both automatic sliding or swinging models, will feature a microprocessor controller which outputs DC voltage to the motor drive unit. Programmable adjustments to the microprocessor control will allow the user to increase or decrease the speed of the door, adjust the hold open time delay, and many other features.
