Building communication system with at least one door station and at least one residence station

摘要

The system has memories (10, 18) and timing relays (11, 19) attached to processing-/controlling units (9, 17) of residence stations (8, 16). The relays controllingly predetermine different operating modes over a time specification and/or a date respective to an actual weekday. Door station-information is stored in the memories. The processing-/controlling units transfer the stored door station-information to a door station (1) by a door station-information-signal (IT) during reception of a bell signal (KL) and occurrence of one of the operating modes with the unconnected bell signal.
