Automatic doors

Automatic doors are doors which open automatically when approached by someone, rather than needing to be opened manually with a door handle or bar. In addition to opening automatically, some automatic doors can also be activated by hitting a button which causes the doors to open. These doors are commonly used in commercial and industrial settings, and they can be extremely useful in a wide variety of environments.

Designs for automatic doors vary. Some slide open, while others consist of panels which fold when people enter or exit, and others swing in or out like conventional doors. The doors are equipped with a motion sensor which can detect people when they approach, and the sensitivity of the sensor can be adjusted as needed. If a button can be used to activate the doors, it is usually low to the ground so that it can be accessed by wheelchair users, and it is large and clearly marked.

These doors require electricity to operate, with electricity driving the motor which opens the doors. Many automatic doors have a manual override so that in the event of a power failure or a mechanical problem, the doors can still be opened. The doors are also designed to be sensitive to obstacles in the doorway, so that they will not close on someone or something which happens to be in the middle of the path of the doors. These safety measures ensure that automatic doors are safe in a variety of situations.
