Abstract

Claims (29)

1. A method for testing a fire alarm system, the method comprising:

establishing a wireless connection via two or more wireless nodes deployed between a control panel of the fire alarm system and a testing computer;

providing each of the wireless nodes with a battery and/or a power port for providing power to the node, a wireless transceiver that transmits event data from the control panel to the testing computer over two wireless links, and a node controller for operating the wireless transceiver and maintaining the two wireless links; and

a technician activating devices of the fire alarm system, event data being sent from the control panel to the testing computer via the one or more wireless nodes and over the wireless connection.

2. The method according to claim 1 , further comprising sending the event data from the testing computer to a central operations system and from the central operations system to a mobile computing device operated by the technician.

3. The method according to claim 1 , wherein establishing the wireless connection comprises connecting a primary mesh node to the control panel via a wired connection.

4. The method according to claim 3 , wherein establishing the wireless connection comprises deploying one or more secondary mesh nodes in the building of the control panel, wherein the wireless connection extends from the primary mesh node through the one or more secondary mesh nodes to the testing computer.

5. The method according to claim 1 , wherein establishing the wireless connection further comprises deploying secondary mesh nodes in connection with devices of the fire alarm system.

6. The method according to claim 3 , wherein establishing the wireless connection comprises deploying two or more secondary mesh nodes in the building of the control panel, wherein the wireless connection extends from the primary mesh node and successively through two or more secondary mesh nodes to the testing computer.

7. A testing system for testing a fire alarm system, the system comprising:

a testing computer; and

two or more wireless nodes establishing a wireless connection between a control panel of the fire alarm system and the testing computer, wherein the one or more wireless nodes are deployed between the control panel and the testing computer and event data is sent from the control panel to the testing computer using the wireless nodes;

wherein at least one of the nodes comprises: a battery and/or a power port for providing power to the node, a wireless transceiver that transmits event data from the control panel to the testing computer over two wireless links, and a node controller for operating the wireless transceiver and maintaining the two wireless links.

8. The system according to claim 7 , further comprising: a central operations system and a mobile computing device operated by the technician, the event data being sent from the testing computer to the central operations system and from the central operations system to the mobile computing device.

9. The system according to claim 7 , wherein the one or more wireless nodes includes a primary mesh node connected to a wired port of the control panel.

10. The system according to claim 9 , wherein the one or more wireless nodes further includes one or more secondary mesh nodes deployed in the building of the control panel, wherein the wireless connection extends from the primary mesh node through the one or more secondary mesh nodes to the testing computer.

11. The system according to claim 7 , wherein the one or more wireless nodes includes one or more secondary mesh nodes deployed in connection with devices of the fire alarm system.

12. The system according to claim 9 , wherein the one or more wireless nodes further includes two or more secondary mesh nodes deployed in the building of the control panel, wherein the wireless connection extends from the primary mesh node successively through the two more secondary mesh nodes to the testing computer.

13. A wireless node for a testing system for a fire alarm system, the node comprising:

a wireless transceiver for establishing two or more wireless links to a testing computer;

a wired adapter port for connection to a control panel;

a battery and/or a power port for providing power to the node; and

a node controller for operating the wireless transceiver and maintaining the two wireless links.

14. A node as claimed in claim 13 , wherein the wireless transceiver transmits event data from the control panel to the testing computer over the wireless links.

15. A node as claimed in claim 13 , further comprising a battery for powering the node.

16. A node as claimed in claim 13 , further comprising a power port for receiving external power.

17. A node as claimed in claim 13 , further comprising a power port for receiving external power from a fire alarm device.

18. A node as claimed in claim 13 , wherein the wireless transceiver establishes wireless links with other wireless nodes.

19. A node as claimed in claim 13 , wherein the wireless transceiver establishes wireless links with other wireless nodes to form a mesh network between the control panel and the testing computer.
