Abstract

A security system comprising a plurality of security subsystems each of the security subsystems being discretely located, typically in separate buildings. The security subsystems are interconnected by a system communications bus to enable bi-directional communication between the security subsystems. Each of the security subsystems comprises a user interface, a control panel, a plurality of security devices, a local communications bus, and a panel linking gateway. The panel linking gateway allows data on the local communications bus of each security subsystem to be transmitted to and received from the system communications bus. The security system allows a keypad or other user interface from one security subsystem to access and control a second remote security subsystem.

Claims

1. An alarm security system for monitoring a plurality of premises, comprising a plurality of security subsystems, each of said security subsystems being discretely located, and a system communications bus interconnected to each of said security subsystems to enable bi-directional communication directly between any two of said security subsystems, wherein each of said security subsystems comprises:

a) a local communications bus,

b) a plurality of user interface devices connected to said local communications bus, each of said user interface devices comprising input devices that allow a user to input commands for controlling operation of a security subsystem,

c) a plurality of sensor devices connected to said local communications bus, each of said sensor devices adapted to monitor an area under surveillance and sense if an intruder has entered said area under surveillance and generate an intrusion signal accordingly,

d) a panel linking gateway connected to said local communications bus and to the system communication bus, said panel linking gateway adapted to selectively transfer data between said local communications bus and said system communication bus; and

e) a control panel connected to said local communications bus comprising;

processing circuitry adapted to receive intrusion signals from said sensor devices and determine if an alarm message should be generated;

a memory indicating, for each of said plurality of user interface devices, if a user interface device is associated with said security subsystem or is linked to a different security subsystem;

wherein user interface devices that are associated with said security subsystem interact only with said security subsystem, and wherein user interface devices that are linked to a different security subsystem interact only with said different security subsystem via said panel linking gateway and said system communication bus; and

wherein said processing circuitry is further adapted to link a user interface device associated with said security subsystem to a different security subsystem on request of a user.

2. The security system of claim 1 wherein said local communications bus uses a first protocol for communications, said system communications bus uses a second protocol for communications, and said panel linking gateway allows communication between the local communications bus and the system communications bus.

3. The security system of claim 2 wherein said panel linking gateway reads data from said local communications bus, processes the data from said first protocol to conform to said second protocol, and transmits the processed data to said system communications bus.

4. The security system of claim 2 wherein said panel linking gateway reads data from said system communications bus, processes the data from said second protocol to conform to said first protocol, and transmits the processed data to said local communications bus.

5. The security system of claim 2 wherein said second protocol is an RS485 standard communications protocol.

6. The security system of claim 1 wherein said system communications bus comprises a wide area network.

7. The security system of claim 6 wherein said wide area network is the Internet.

8. The security system of claim 1 wherein said system communications bus interoperates over a telephone network.

9. The security system of claim 1 wherein said system communications bus interoperates over a fiber optics network.

10. The security system of claim 1 wherein said system communications bus interoperates over a satellite network.

11. The security system of claim 1 wherein said system communications bus interoperates in conjunction with a cable modem.

12. The security system of claim 1 wherein said sensor devices comprise a motion sensor.

13. The security system of claim 1 wherein said sensor devices comprise a window sensor.

14. The security system of claim 1 wherein said sensor devices comprise a door sensor.

15. The security system of claim 1 wherein said sensor devices comprise a glass break detector.
