To allow a health personnel to acquire a call from a patient as much as possible, even when a substrate of a nurse call master machine is exchanged or repaired.

The nurse call system includes: corridor a lamp that is installed in a corridor side close to an entrance of each ward where a nurse call slave machine 1 is installed and displays that a call has been performed by the nurse call slave machine 1; a nurse call master machine 20 for notifying that the call has been performed by the nurse call slave machine 1; and a control machine 10 for controlling communication between the nurse call master machine 20 and the nurse call slave machine 1. When an operation part 25 provided in the nurse call master machine 20 is operated, a preliminary notification part 9 for performing a notification by sound is operated only when the call is performed by the nurse call slave machine 1, so that, even when a substrate of the nurse call master machine 20 is exchanged or repaired, a health personnel who hears the notification sound by the preliminary notification part 9 of the corridor lamp 5 can acquire the calling of the patient.
