  The present invention relates to an interphone device and an interphone system in which an alarm device is connected to the interphone device.

  There is an alarm device of a type that includes a sensor and a notification device that performs notification based on a detection signal of the sensor, and that performs both abnormality detection and notification by itself. In this type of alarm device, since the alarm is integrated with the sensor, the user may not notice the notification by the alarm at a place away from the place where the abnormality has occurred.

  Therefore, an intercom system with an alarm function has been developed in which a notification by an alarm device is transferred to an interphone device at a remote location and notified by the interphone device. In this interphone system with an alarm function, an alarm can be quickly notified to a user who is away from the place where the abnormality has occurred by performing the notification by the alarm device also in the interphone apparatus away from the alarm device.

  In addition, in this type of intercom system, in order to eliminate the inconvenience caused by continuous notification when there is a normal notification due to the occurrence of an abnormality or a false alarm due to a faulty wiring or alarm device failure, it is useless. There are those in which the intercom device is provided with a notification stop key so that the notification can be stopped, and those in which the notification is automatically stopped after a certain period of time. In this case, the transfer signal from the alarm device is continuously output, but the notification is stopped in the intercom device.

Further, for example, in Patent Document 1, in the intercom system of an apartment house, even when the alarm sound stop / restore button on the room unit side is pressed after the fire detector is activated, Until the fire detector is restored by pressing, the outdoor indicator lights are continuously turned on or blinked so that managers can know which fire detector of the dwelling unit has been activated. A residential intercom system is described.
