PROBLEM TO BE SOLVED: To provide an intercom system for displaying a call by using a large current in making a call in a wiring capable of applying only the small current such as an LAN cable. SOLUTION: In a nurse call intercom system in which a calling signal is transmitted to a nurse call master set according to a calling operation from a slave set at a bed and a corridor light displays the calling, a trunk line has a wiring mode in which a plurality of corridor lamps are connected via a jumper line with a control device as an end point, and the corridor lamps are equipped with super capacitors for storing currents as power sources from the control device via the trunk line and discharging deficient currents in currents from the trunk line in displaying a calling, thereby reducing the current in calling to simplify the wiring.
