Abstract

Systems and methods for dynamic output control hierarchy for wireless fire systems and for fire protection before and during the installation thereof are provided. Systems can include a fire system control panel, a gateway device coupled to the control panel, and a mesh network coupled to the gateway device. Responsive to the gateway device detecting a loss of communication with the control panel or a failure of the control panel, the gateway device can control activation of output devices in the mesh network. Responsive to a first device in the mesh network detecting a failure of the gateway device, the first device can control activation of the output devices in the mesh network. In some embodiments, the first device can control activation of the output devices of a second device in the mesh network, and in some embodiments, the first device can self-control activation of its own output devices.

First claim

What is claimed is:

1. A method, comprising:
providing a gateway device coupling a fire system control panel to a mesh network;
a first device in the mesh network detecting a failure of the gateway device; and
responsive to the first device detecting the failure of the gateway device, the first device self-controlling activation of one or more output devices of the first device in the mesh network;
wherein the first device is preconfigured with instructions to control the activation of the output devices in the mesh network without the gateway device.

2. The method of claim 1 , further comprising the fire system control panel, via the gateway device, controlling the activation of the output devices in the mesh network prior to the failure of the gateway device.

3. The method of claim 1 , further comprising the first device transmitting a signal with an alarm message to the gateway device.

4. The method of claim 3 , further comprising the gateway device transmitting the signal with the alarm message to the fire system control panel.

5. The method of claim 1 , wherein the failure of the gateway device includes the fire system control panel or the gateway device being jammed.

6. A method, comprising:
providing a gateway device coupling a fire system control panel to a mesh network;
a first device in the mesh network detecting a failure of the gateway device; and
responsive to the first device detecting the failure of the gateway device, the first device self-controlling activation of one or more output devices of the first device in the mesh network, wherein the first device includes a hybrid input-output device;
wherein the first device is preconfigured with instructions to control the activation of the output devices in the mesh network without the gateway device.

7. The method of claim 6 , further comprising the first device dropping out of the mesh network.

8. The method of claim 6 , further comprising the fire system control panel, via the gateway device, controlling the activation of the output devices in the mesh network after restoration of the gateway device.

9. The method of claim 6 , wherein the gateway device synchronizes each of the output devices in the mesh network.

10. The method of claim 6 , further comprising the first device controlling the activation of the output devices of a second device in the mesh network.

11. The method of claim 6 , wherein the first device includes a sounder device.

12. The method of claim 11 , wherein the first device activates the output devices of the first device responsive to the activation of an input device of the first device.

13. The method of claim 12 , wherein the activation of the input device includes the input device detecting an ambient condition.

14. A system comprising:
a fire system control panel;
a gateway device coupled to the fire system control panel; and
a mesh network coupled to the gateway device,
wherein, responsive to the gateway device detecting a loss of communication with the fire system control panel or a failure of the fire system control panel, the gateway device controls activation of one or more output devices in the mesh network;
wherein a first device of the mesh network is preconfigured with instructions to control the activation of the output devices in the mesh network without the gateway device, and wherein, responsive to the first device in the mesh network detecting a failure of the gateway device, the first device controls the activation of the output devices in the mesh network; and
wherein the first device controls the activation of the output devices of a second device in the mesh network.

15. The system of claim 14 , wherein the first device transmits a signal with an alarm message to the gateway device.

16. The system of claim 14 , wherein the first device includes a hybrid input-output device.

17. The system of claim 16 , wherein the first device self-controls activation of the output devices of the first device responsive to the activation of an input device of the first device.

18. The system of claim 14 , further comprising the fire system control panel controlling the activation of the output devices in the mesh network prior to the loss of the communication with the fire system control panel or prior to the failure of the fire system control panel.

19. The system of claim 14 , further comprising the fire system control panel controlling the activation of the output devices in the mesh network after restoration of the communication with the fire system control panel or after restoration of the fire system control panel.
