<p>Anti-intrusion apparatus, particularly for passage openings, like doors, windows, or similar, comprising sensing means (1, 201, 301), which detect the passage or the attempted passage through an opening (A), and generate or modify a signal, and electronic means (12) for recognizing and processing the said signal for the control of warning means or actuators of other kind. The apparatus comprises at least one sensor (1) or one group of sensors supported so as to be movable like a curtain (2, 3, 4, 5) or similar from an idle position, in which the sensors (1) are gathered on one side of the opening (A), leaving it substantially clear, into an operating position, in which the sensors (1) are arranged according to a predetermined design on the whole extension of the opening (A), whereas the sensors (1) are of the type that can generate a signal or modify a reference signal when they are moved from the position they take with no stresses, like movements or similar, acting thereupon, into their operating condition.</p> |
