Abstract

A system and method for connecting a security system using a network. The security system includes at least two discrete parts and is connected using a local area network. The security system also includes a first dedicated, hard-wired field bus, a first plurality of peripheral devices, a control panel, a first transfer device, a second transfer device, a second dedicated, hard-wired field bus, and a second plurality of peripheral devices. The control panel is configured to send data through the first field bus. Each of the first plurality of peripheral devices is coupled to the first field bus and is configured to receive the data from the control panel. The first transfer device is connected to the control panel and is configured to packetize the data from the control panel and send the packetized data through the local area network. The second transfer device is coupled to the second field bus and is configured to receive the packetized data from the first transfer device and depacketize the packetized data. Each of the second plurality of peripheral devices is coupled to the second field bus and is configured to receive the data from the second transfer device.

Claims

1. A security system connected with a local area network, the security system comprising:

a first dedicated, hard-wired field bus;

a control panel sending data through the first field bus;

a first plurality of peripheral devices coupled to the first field bus;

wherein each of the first plurality of peripheral devices receives data from the control panel;

a first transfer device connected to the control panel;

wherein the first transfer device packetizes the data from the control panel and sends the packetized data through the local area network, and

wherein the first transfer device generates an acknowledgment message in response to the data from the control panel before the packetized data is sent through the local area network;

a second dedicated, hard-wired field bus;

a second transfer device coupled to the second field bus;

wherein the second transfer device receives the packetized data from the first transfer device and depacketizes the packetized data; and

a second plurality of peripheral devices coupled to the second field bus;

wherein each of the second plurality of peripheral devices receives data from the second transfer device, generates a second acknowledgement message in response to the data from the second transfer device, and sends the second acknowledgement message to the second transfer device,

and wherein the second transfer device does not send the second acknowledgment message to the control panel.

2. The security system of claim 1, wherein the first transfer device is further configured to send the acknowledgment message to the control panel.

3. The security system of claim 1, wherein the first transfer device is incorporated into the control panel.

4. The security system of claim 1, wherein the second transfer device is incorporated into one of the second plurality of peripheral devices.

5. The security system of claim 1, wherein the first and second transfer devices are configured using a browser.

6. The security system of claim 1, wherein the first transfer device is coupled to the first field bus.

7. The security system of claim 1, wherein the first transfer device is a master device and the second transfer device is a slave device.

8. The security system of claim 7, wherein the slave device includes knowledge of each of the second plurality of peripheral devices attached to the second field bus.

9. The security system of claim 8, wherein the master device includes knowledge of each of the second plurality of peripheral devices connected to each of a plurality of slave devices.

10. A method for connecting a security system using a local area network, the method comprising:

coupling a first plurality of peripheral devices to a first dedicated, hard-wired field bus;

sending data from a control panel through the first field bus;

receiving the data from the control panel at each of the first plurality of peripheral devices;

connecting a first transfer device to the control panel;

converting the data from a first form to a second form using the first transfer device;

sending the converted data through the local area network;

generating an acknowledgment message in response to the data before the converted data is sent through the local area network;

coupling a second transfer device to a second dedicated, hard-wired field bus;

coupling a second plurality of peripheral devices to the second field bus;

receiving, at the second transfer device, the converted data from the first transfer device;

converting the converted data from the second form to the first form using the second transfer device;

receiving the data from the second transfer device at each of the second plurality of peripheral devices;

generating a second acknowledgement message in response to the data from the second transfer device using each of the second plurality of peripheral devices;

sending the second acknowledgement message to the second transfer device; and

emulating the control panel using the second transfer device.

11. The method of claim 10, further comprising sending the acknowledgment message to the control panel.

12. The method of claim 10, further comprising incorporating the first transfer device into the control panel.

13. The method of claim 10, further comprising incorporating the second transfer device into one of the second plurality of peripheral devices.

14. The method of claim 10, further comprising configuring the first and second transfer devices using a browser.

15. The method of claim 10, further comprising coupling the first transfer device to the first field bus.

16. The method of claim 10, further comprising configuring the first transfer device as a master device and the second transfer device as a slave device.

17. The method of claim 10, wherein converting the data from the first form to the second form includes packetizing the data.

18. The method of claim 10, wherein converting the data from the second form to the first form includes depacketizing the data.
