<p>A scheme for assembling the external stations of intercom and video-intercom systems, comprising a series of modular positioning frames (3A-3C), which are fixed either to a series of flush-mounting modular boxes (2A-2C) or to a series of containers applied directly to the surface of a wall (11) and which determine the positioning of a series of functional modules (7A-7L) for analog and/or digital systems. PLastic or aluminium modular faceplates (5A-5H; 6A-6T) are provided for covering the front surface of each functional module (7A-7L), or one-piece steel faceplates for covering the entire external station, these comprising control and/or indicating means for the respective module (7A-7L). <IMAGE></p> |
