What Is An Automatic Sliding Door

An automatic sliding door is an automated door way that utilizes sliding door panels. As a pedestrian approaches the automatic sliding door, moving door panels will automatically slide open, allowing the pedestrian to pass through the entryway. As the pedestrian enters the building and passes through the doorway, the moving door panels automatically close behind them.

How Does An Automatic Sliding Door Work

An automatic sliding door consists of the aluminum glass door panels, door frame jambs, and door frame header. The door frame header houses the dc motor, control system, timing belt, roller top track, and door panel roller carriages. On both the interior and exterior sides of the header are dual technology motion and presence sensors. The motion sensors are designed to detect pedestrians approaching the door. Once pedestrians are directly beneath door frame header, they are in the threshold zone of the automatic sliding door, and the presence or safety sensors detect them. The presence safety sensors are designed to keep the moving door panels open and for them not to close on any pedestrians in the threshold zone of the automatic sliding door. Once the pedestrians have completely passed through the door way, the motion sensors and presence safety sensors do not detect any pedestrians, allowing the moving door panels to close.

When a pedestrian first approaches an automatic sliding door, the motion sensor detects them. The motion sensor sends a relay signal to the control system inside of the door frame header, signaling to the control system to open the doors. The control unit sends voltage to the DC motor, powering the DC motor on. Attached to the end of the DC motor output spindle is a worm gear that meshes into a gearbox. As the DC motor runs, the worm gear on it's output spindle rotates with high revolutions turning the gearbox. The internal gears within the gearbox reduce the gear ratio. On the output shaft of the gearbox is a timing belt pulley. On the opposite side of the motor/gearbox assembly is an idler pulley. A timing belt wraps around the gearbox pulley and idler pulley.

At the top of the moving door panels are carriage rollers. These rollers are designed to sit on the top roller track located inside of the door frame header. This allows the door panels to smoothly glide open and closed. The portion of the door panel which contains the carriage rollers is connected to the timing belt by belt clips. A bottom track is located between the door frame jambs. At the bottom rail of the door is a bottom guide assembly which is designed to glide along the bottom track. The bottom guide prevents the moving door panels from derailing or moving out of alignment.

As the DC motor is powered on by the controller, the gearbox output pulley rotates, causing the timing belt to move with the pulley. Since the door panels are connected to the timing belt, the door panels slide open.

Once the pedestrian passes through the door way and the motion and presence sensors do not detect them, the controller reverses the polarity of the voltage sent to the DC motor. This causes the DC motor to rotate in the opposite direction, allowing the gearbox output shaft belt pulley to rotate in the opposite direction, causing the door panels to slide into the closed position.

Configurations Of Automatic Sliding Doors

Automatic sliding doors come in variety of configurations.

Bi-Part Automatic Door Configuration

A bi-part automatic sliding door consists of 4 door panels. The two moving door panels meet together at the center of the opening. While the two outermost door panels are stationary and do not slide. The two moving door panels slide open when activated, allowing pedestrians to pass through the center of the door way.

Single Slide Automatic Door Configuration

A single slide automatic sliding door consists of 2 door panels. One moving door panel and one stationary door panel. Single slide automatic sliding doors are handed. They can be manufactured so the moving door panel slides open to the right, or manufactured so the moving door panel slides open to the left.

Telescoping Automatic Door Configuration

Telescopic automatic sliding doors are available in bi-part configuration with 6 door panels (4 moving door panels and 2 stationary door panels), or in single slide configuration with 3 door panels (2 moving door panels and 1 stationary door panel). Telescopic automatic sliding doors are similar to the design of elevator doors in the fact that the moving door panels slide open and stack together. They are ideal for automatic door applications that require extra door opening.

Emergency Break Out Function

In the United States, due to emergency safety requirements set forth by the NFPA 101 and ANSI A156.10, the moving automatic door panels must be able to swing outward in case of an emergency. A ball detent catch is utilized at the top rail of the door, allowing the door panel to detach from the doors top carriage so that the door can swing out in emergency. The United States is actually one of the only countries that requires this feature, since countries like UK, China, Korea, Germany, etc do not.

Full Break Out Automatic Sliding Door

This automatic door type is when both moving door panels and stationary door panels have the ability to swing out in case of emergency. This is the most popular automatic sliding door configuration.

Fixed Side Lite Automatic Door

This automatic door type is when only the moving door panels have the ability to swing out in case of an emergency.
