Automatic Sensor Door System

Sensors in automatic doors detect movement, pressure, or infrared pictures, causing the doors to open or shut. The doors will open as soon as pressure or movement is sensed, and they will shut when the detectors can no longer sense anything. Automatic doors effectively contribute to energy saving and reduce annual heating and cooling costs. Doors open only when activated and automatically close so to eliminate the doors being left open. They also prevent air-conditioning from escaping and outside air and dust from entering. Automatic door means a door equipped with a power-operated mechanism and controls that open and close the door automatically upon receipt of a momentary actuating signal. The switch that begins the automatic cycle may be a photoelectric device, floor mat, or manual switch.
