Abstract

Methods and systems for operating a point device included in a system of point devices. One method includes transmitting a query, with a transceiver included in the point device, to at least one device external to the point device for system state information and receiving, with the transceiver, a response from at least one device external to the point device in response to the query. The method also includes determining, with an electronic processor included in the point device, a current state of the system of point devices based on the received response and automatically modifying, with the electronic processor, operation of the point device based on the current state of the system of point devices.

transmitting a query, with a transceiver included in the point device, to at least one device external to the point device for system state information;

receiving, with the transceiver included in the point device, a response from the at least one device external to the point device to the query for system state information;

determining, with an electronic processor included in the point device, a current state of the system of point devices based on the response;

automatically modifying, with the electronic processor included in the point device, operation of the point device based on the current state of the system of point devices;

tracking a number of changes in the current state of the system of point devices;

comparing the number of changes in the current state of the system of point devices to a predetermined threshold; and

when the number of changes in the current state of the system of point devices exceeds the predetermined threshold, automatically triggering a malfunction response.

2. The method of claim 1, wherein determining the current state of the system of point devices includes obtaining the current state of the system of point devices from the response.

3. The method of claim 1, wherein determining the current state of the system of point devices includes determining whether the system of point devices is in at least one selected from a group consisting of an armed state, a disarmed state, an installation state, and a test state.

4. The method of claim 1, wherein automatically modifying operation of the point device includes automatically modifying a mode of operation of the point device, wherein the mode of operation of the point device includes at least one selected from a group consisting of a security sensor mode, an occupancy sensor mode, an installation mode, and a test mode.

5. The method of claim 1, wherein automatically modifying operation of the point device includes at least one selected from a group consisting of disabling a function performed by the point device and modifying an operating parameter of the point device.

6. The method of claim 1, further comprising:

detecting data with at least one input mechanism included in the point device, wherein the data relates to an environment around the point device,

wherein automatically modifying operation of the point device is based on the data and the current state of the system of point devices.

7. The method of claim 1, further comprising:

detecting an event; and

determining whether to report the event to a master controller based on the current state of the system of point devices.

8. The method of claim 1,

wherein the malfunction response includes at least one selected from a group consisting of maintaining a current operation of the point device, performing diagnostics on the system of point devices, notifying users via one or more local or remote mechanisms, and switching from a first master controller to a second master controller.

9. A security system comprising:

a point device included in a system of point devices, the point device including an electronic processor, wherein the electronic processor is configured to

transmit a query to at least one device external to the point device for system state information,

receive a response from the at least one device external to the point device to the query for system state information,

determine a current state of the system of point devices based on the response,

automatically modify operation of the point device based on the current state of the system of point devices,

track a number of changes in the current state of the system of point devices,

compare the number of changes in the current state of the system of point devices to a predetermined threshold,

when the number of changes in the current state of the system of point devices exceeds the predetermined threshold, automatically trigger a malfunction response, and

when the number of changes in the current state of the system of point devices does not exceed the predetermined threshold, automatically modify the operation of the point device based on the current state of the system of point devices.

10. The system of claim 9, wherein the electronic processor is further configured to obtain the current state of the system from the response.

11. The system of claim 9, wherein the current state of the system of point devices includes at least one selected from a group consisting of an armed state, a disarmed state, an installation state, and a test state.

12. The system of claim 9, wherein the wherein the malfunction response includes at least one selected from a group consisting of preventing a modification to the operation of the point device, performing diagnostics on the system of point devices, notifying users via one or more local or remote mechanisms, and reporting detected events to a new master controller different from a current master controller.

13. The system of claim 9, wherein the electronic processor is further configured to

detect an event, and

determine whether to report the event to a master controller based on the current state of the system of point devices.
