Abstract
A multiple dwelling house interphone system include a collective entrance machine, a dwelling room master device, a management master device, and a sensor. When the sensor detects the occurrence of the abnormality, an abnormality occurrence signal is transmitted from the dwelling room master device to the management master device, and the dwelling room master device and the management master device emit emergency alarms. The management master device includes a display section and a display control section. The display control section displays an alarm stop button to stop an emission operation on the display section when the abnormality occurrence signal is received and the emission is started. When the alarm stop button is operated, the display control section subsequently displays an emission source call button to call the dwelling room master device as a transmission source of the abnormality occurrence signal.
