Art. 05512 - Electronic control unit for multiple interphone connections

Electronic control unit for managing 4 outdoor interphone stations and 3 indoor interphone handsets. It can be connected by means of a screw terminal block to 4 outdoor interphone handsets (Art. 05515, 55012, 55013, 55033) or by means of an 8-pole plug to 3 indoor multi-door interphone handsets (Art. 05514). An acoustic and visual (LED) signal on the multiport handsets indicates a call from an external interphone station. The first handset that is picked up establishes communication with the external calling station, excluding the 2 handsets. Further calls during the conversation are signalled on the 3 handsets and put on hold according to the arrival priority.
