B and a communication device 4C that can communicate with the intercom 5A provided in the rooms 11 to 13 of the apartment 1 are provided.

[0010] The condominium 1 has a power line 6 of AC100V which is a commercial power supply, a common entrance 2, and each of the rooms 11-1.
3 and the like.
Unlocking device 5B that outputs an unlocking command signal to auto-locking device 3A provided in each of .about.13 and intercom 5A are connected.
Is connected to the entrance door control device 7.

Here, the entrance door control device 7 is a
Signal and the automatic lock device 3A
7A, which outputs a signal to the telephone, and interphones 5 of predetermined living rooms 11 to 13 formed by the exchange 7A.
A signal superimposing circuit 7B for superimposing a call signal specifying A and a voice signal from the microphone of the communication device 4C on the power line 6 and transmitting the signal to the interphone 5A, and a voice signal from the interphone 5A superimposed on the power line 6 and unlocking. The unlock command signal from the device 5B is discriminated, and the communication device 4 is exchanged via the exchange 7A.
Output to the C speaker and the auto-lock device 3
And a new joint discriminating circuit 7C that outputs an unlock command signal to A. Here, when the exchange 7A recognizes, in addition to the unlock signal transmitted from the unlocking device 5B, the ID registered in advance in the ID card reading unit 4B of the entrance device 4, the auto-lock device 3A issues the unlock command signal. Is output.

Next, the operation of this embodiment will be described.

First, when a resident of the apartment 1 returns home, an ID (not shown) owned by the ID card reading unit 4B is provided.
When the D card is inserted and the ID registered in advance is recognized, an unlock command signal is output to the auto-locking device 3A via the exchange 7A, and the door 3 is unlocked. You can enter the shared entrance.

Next, when a guest comes to the living room 11 of the apartment 1, when the guest operates the number 11 of the living room 11 that is memorized in advance through the ten key 4A, the signal of the living room 11 pressed by the ten key 4A is The exchange 7A converts the call signal into a call signal for the intercom 5A in the living room 11, and the converted call signal is superimposed on the power supply to the power line 6 by the signal superimposing circuit 7B and transmitted. Intercom 5 in this room 11
Living room 11 receiving the call signal of A via power line 6
Interphone 5A makes a ringing tone. When the receiver of the intercom 5A is picked up, the call signal from the intercom 5A is transmitted to the interphone 5A-the power line 6-.
A signal discrimination circuit 7C-switch 7A-communication device 4C is output to the speaker of the communication device 4C of the entrance device 4 in the order, and a communication signal from the microphone of the communication device 4C is transmitted by the communication device 4C-switch 7A-signal superimposing circuit 7C. -Wire 6-Interphone 5
By outputting to the intercom 5A in the order of A, the conversation between the intercom 5A and the communication device 4C can be performed, and when the resident of the living room 11 recognizes the guest and operates the unlocking device 5B, the unlock command signal is output. 5B-power supply line 6-signal discriminating circuit 7C
