Calls in the Residential Building When calling the residential information panel 102 from the lobby intercom 101 in the residential building to make a call, operate the numeric keypad 101a of the lobby intercom 101 and enter the dwelling unit number. The house number is transmitted to 1 and the house number is transmitted from the house monitoring panel 1 to each house information panel via a multiplex signal line. Then, in the house information panel 102 having the matching unit number, a ringing sound is output by an internal circuit and a call line is connected, and a call is made with the lobby intercom 101 via a call signal line IS.

Security monitoring and control in the dwelling building When a disaster prevention sensor S such as a fire detector or a gas detector connected to the dwelling house information panel 102 provided in the dwelling unit issues an alarm, the dwelling house information board 102 sends a signal via the multiple signal line l. Then, a security signal with an address corresponding to the dwelling unit number is transmitted to the ward monitoring panel 1 by a multiplex signal.
In response to this security signal, an alarm is displayed.

Security monitoring control in the management center As described above, the security signal transmitted from the house information panel 102 to the house building monitoring panel 1
Is transmitted to the multiplexed signal line 11 through the control signal transmission / reception unit 1a as a multiplexed signal with a unique address of the multiplexed signal. The multiplexed signal is received by the control signal transmission / reception unit 2a of the center monitoring panel 2 on the management center side. And performs necessary control processing such as alarm notification.

Calls between the management center and the housing information panel From the center monitoring panel 2 to the housing information panel 10 of one of the residential buildings
When calling by calling 2 and operating the ten key 2c of the center monitoring panel 2 and inputting the dwelling unit number, the dwelling unit number is output from the control signal transmitting / receiving unit 2a to the multiplex signal line l1.

This dwelling unit number is transmitted to the dwelling unit monitoring panels 1 of all dwelling units via the multiplex signal line l1, but the dwelling unit monitoring panel 1 of the dwelling unit to which the dwelling unit number belongs is transmitted through the control signal transmitting / receiving unit 1a. Import the dwelling unit number. Then, the dwelling unit number is transmitted from the dwelling monitoring panel 1 to each housing information panel 102 via the multiplex signal line l, and the housing information panel 102 having the matching dwelling unit number outputs a ringing sound and connects a telephone line by the internal circuit. Then, a call is made with the center monitoring panel 2 via the call signal lines lS and l2.

As described above, in the system of the present invention, the multiplex signal line l1 and the call signal line
By connecting the l2 and connecting the multiplex signal line l1 and the call signal line l2 to the center monitoring panel 2, centralized management of a plurality of residential buildings can be efficiently performed on the management center C side. Since only the center monitoring panel 2 needs to be provided in C, space can be saved.

Also, even if a failure such as a disconnection or short circuit occurs in the multiplex signal line l1 and the call signal line l2 laid between each of the housing buildings J1 to Jn and the management center C, the inside of each of the housing buildings J1 to Jn becomes independent. It is possible to carry out security monitoring control and telephone conversation, thereby providing a system with improved reliability.
