SUBSTANCE: detecting unit (14) generates areas of detection located in 2D manner on the floor surface near a door panel (12). Each area of detection is made as capable of detection of a human being or an object using an infrared light regardless of other areas of detection.

SUBSTANCE: proposed security system for automatic gates comprises at least one moveable wing, capable of blocking passage, the boundaries of which are defined by immovable elements of the gates. The system has several transmitters and receivers of infrared beams. The transmitted and received beams define the security zone, corresponding to the dimensions of the working region of the gates. Interruption of one of the said beams triggers an alarm state. The security zone has a quadrilateral shape. The perimetre of the zone is defined by the barrier, formed by the closed gates, two sides, perpendicular to the barrier and outside the wings of the gates, and an opposite side, which is parallel the barrier and closes the security zone. Transmitters and receivers are fitted at points of intersection of these sides, which define the security zone. The alarm state leads to stopping and/or reverse motion of at least one wing of the gate.
