Abstract
An access control installation adapted for controlling access from a first zone to a second zone, said installation comprising: at least one separating panel separating the first and second zones, said separating panel having at least one moving closure element (1) adapted for selectively opening or closing an opening; at least one opening actuator (3a, 3b) adapted for causing the closure element (1) selectively to prevent or to allow access via the opening; and a control circuit (5) for controlling the opening actuator. Said installation further comprises at least one sound sensor (6) fastened to the separating panel on the same side as the second zone and adapted for detecting knocks on the first surface of said separating panel, and the control circuit (5) is adapted for: recognizing a predetermined code represented by a particular sequence of knocks on the first surface; and controlling the opening actuator as a function of the recognized code.
