<P>PROBLEM TO BE SOLVED: To provide an apartment building interphone system capable of identifying a dwelling unit in which an alarm has been activated even after the alarm has been recovered and a display of alarm information has gone off. <P>SOLUTION: In an apartment building interphone system, a living room master unit 2 has an alarm button 28 and is connected to a fire sensor 10 and a gas leakage sensor 11. Upon receiving an operation of the alarm button 28 or an activation of the fire sensor 10 or the gas leakage sensor 11, a master unit CPU 25 transmits an abnormality occurrence signal to a control unit 3, the signal including transmission source information such as a type of abnormality, living room information, and so on. The abnormality occurrence signal is transmitted to an apartment building entrance unit 1 via the control device 3. The apartment building entrance unit 1 activates the alarm upon receiving the abnormality occurrence signal, and at the same time, stores the received transmission source information in an entrance unit memory 15 and outputs the alarm from a notification relay output section 20 to report the abnormality to a security company. Thereafter, upon receiving a predetermined display operation, the apartment building entrance unit 1 displays the transmission source information stored in the entrance unit memory 15 on a display section 16. <P>COPYRIGHT: (C)2012,JPO&INPIT |
