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.
