Abstract

Methods and systems for transferring alarm information by sending an alarm message containing information about an alarm. The alarm message includes an alarm counter indicator that indicates whether an alarm status has changed from a previous alarm message. The alarm message also includes one or more indications of alarm conditions indicating an alarm state or an alarm source. Furthermore, the alarm message includes an alarm length that indicates a number of alarm conditions included in the alarm message.

an alarm length that indicates a number of the alarm conditions included in the alarm message;

receiving, by the electronic device, an alarm status update message via the fabric network; and

hushing the alarm using the received alarm status update message that comprises an alarm update counter indicator including a counter value that matches the status value of the alarm counter indicator of the alarm message.

2. The method of claim 1, comprising hushing the alarm using the received alarm status update message that comprises one or more update indications of the alarm conditions being updated.

3. The method of claim 1, wherein hushing the alarm comprises blocking a remote device from hushing the alarm through a remote connection via an alarm status update message based at least in part on the smoke condition.

4. The method of claim 1, wherein hushing the alarm comprises:

allowing a first remote device type to hush the alarm through a remote connection via a first alarm status update message; and

blocking a second remote device type from hushing the alarm through the remote connection via a second alarm status update message based at least in part on the smoke condition.

5. The method of claim 1, comprising:

propagating the alarm to one or more devices in the fabric network, wherein propagating the alarm within the fabric network comprises sending the alarm message to a first device having a first device type without sending the alarm message to a second device having a second device type.

6. The method of claim 1, wherein the alarm message comprises an originating node identifier that identifies an originating device within the fabric network that originated the alarm, wherein the originating node identifier comprises a 64-bit Internet Protocol (IP) unique identifier used to identify the originating device to a specific device within the fabric network.

7. The method of claim 1, wherein the message comprises an extended location identifier for an originating device within the fabric network that originated the alarm, wherein the extended location identifier comprises a 128-bit identifier of the originating device as a specific device within the fabric network.

8. The method of claim 1, wherein the alarm counter indicator comprises an 8-bit value that indicates an alarm version for the alarm message indicating whether the alarm state has been updated, wherein the alarm counter indicator starts at an initial value and, the alarm counter indicator is incremented each time the alarm status is updated.

9. The method of claim 8, comprising:

resolving the alarm that corresponds to the alarm message; and

in response to resolving the alarm, resetting the alarm counter indicator to the initial value once the alarm has been resolved, wherein the initial value indicates that no current alarm exists or the alarm has been resolved.

10. A non-transitory, computer-readable medium having stored thereon instructions that, when executed, are configured to cause a processor to:

transmit an alarm message containing information about an alarm via a fabric network, wherein the alarm message comprises;

an alarm counter indicator that includes a status value that indicates whether an alarm status has changed from a previous alarm message;

one or more indications of alarm conditions indicating an alarm state or an alarm source, wherein the one or more conditions comprises presence of carbon monoxide; and

an alarm length that indicates a number of alarm conditions included in the alarm message;

receive an alarm status update message via the fabric network; and

hush the alarm based on the received alarm status update message that comprises an alarm update counter indicator including a counter value that matches the status value of the alarm counter indicator of the alarm message.

11. The non-transitory, computer-readable medium of claim 10, wherein the one or more indications further comprise at least one of a smoke condition, a temperature condition, a natural gas condition, a humidity condition, and a security condition.

12. The non-transitory, computer-readable medium of claim 10, wherein transmitting the alarm message comprises:

transmitting the alarm message as a multicast message that is to be propagated to neighboring devices to which communication may be established;

or

transmitting the alarm message as a unicast message that is addressed to one or more destination devices.

13. The non-transitory, computer-readable medium of claim 10, wherein the transmission of the alarm message comprises retransmitting the alarm message periodically while the alarm has not been resolved and a threshold duration for alarm retransmission has not been surpassed.

14. The non-transitory, computer-readable medium of claim 10, wherein when the alarm source is null or not explicitly listed in the alarm condition of the one or more alarm conditions, the alarm state for the alarm condition comprises a standby state for the alarm that indicates that a current alarm is not active.

15. The non-transitory, computer-readable medium of claim 10, wherein when the one or more indications of alarm conditions comprise an implicit indication of alarm condition when explicit indications of alarm conditions are missing from the alarm message when the alarm length is set, wherein an implicit indication of alarm conditions indicate that the alarm message comprises an all clear signal.

16. An electronic device, comprising:

a network interface to a fabric network;

memory; and

a processor configured to;

send an alarm message containing information about an alarm using the network interface, the alarm message including;

an alarm counter indicator including a status value that indicates whether an alarm status has changed from a previous alarm message;

one or more indications of alarm conditions indicating an alarm state or an alarm source, wherein the one or more conditions comprises the presence of natural gas; and

an alarm length that indicates a number of alarm conditions included in the alarm message;

receive an alarm status update message via the fabric network; and

hush the alarm using the received alarm status update message that comprises an alarm update counter indicator including a counter value that matches the status value of the alarm counter indicator of the alarm message.

17. The electronic device of claim 16, wherein the processor is configured to receive, via the network interface from another device, an incoming alarm message that comprises:
