Skyline digitizer module to be incorporated into both doorphone and video door entry Skyline panels to configure MDS CITY panels or MDS DIRECT panels. The same device allows both plate configurations. It detects the pressing of the call button or the keypad on the panel and sends the corresponding code. It is also responsible for activating / deactivating the amplifier and the on-board camera (if it is video), in addition to the installation's video changer (if it exists). It works both in combination with SKYLINE keypad MODULES (7439) and push buttons (7371, 7372, 7376, 7367, 7368 and 7375, which do not require a call extension module), and even allows combinations of both types of modules.
