  The control means 31 is an example of simultaneous broadcast means for controlling the entire management room base unit 30 and for simultaneously broadcasting the sound recorded in the sound memory 36. This simultaneous broadcast means has a broadcast execution button 32 for performing simultaneous broadcast, and is a means for outputting the sound recorded in the sound memory 36 to the house information board of each dwelling unit via the sound signal line La.

  The operation means 32 has a numeric keypad, a trial listening button, a recording start button, a broadcast execution button, and the like. The audition button is an example of audition means for auditioning the sound recorded in the audio memory 36, and is a button to be pressed when auditioning. The recording start button is a button that is pressed before the simultaneous broadcasting is started. When this button is pressed, the sound from the microphone is stored in the sound memory 36. When the broadcast execution button is pressed when starting the broadcast, the contents of the broadcast stored in the audio memory 36 are broadcast.

  The handset 33 is an example of a microphone that inputs voice.

  The call means 34 outputs the audio signal output from the handset 33 to the audio signal line La and sends the audio signal received via the audio signal line La to the handset 33.
