Abstract

A hazard alarm system includes a hazard alarm notification appliance, and a warning detector which detects a warning alert message from an external source (such as a governmental organization). The hazard alarm system processes the warning alert message and issues an alarm system alert via the notification appliance. In issuing the alarm system alert, the hazard alarm system determines whether, how, what, where, and/or when to issue the alarm system alert using the notification appliance

Claims

1. A hazard alarm system, comprising:

a warning device for receiving a warning alert message from a source external to the hazard alarm system;

a system controller in communication with the warning device and receiving the warning alert message from the warning device, the system controller determining whether to issue an alarm system alert based on at least one aspect of the warning alert message received;

a notification appliance in communication with the system controller, the system controller sending the alarm system alert to the notification appliance based on the warning alert message if the system controller determines to issue the alarm system alert; and

at least one hazard detector that detects any of fire, heat, and smoke, the hazard detector in communication with the system controller and being separate from the warning device.

2. The hazard alarm system of claim 1, wherein the warning device comprises a warning receiver for receiving the warning alert message;

and

wherein the system controller is in communication with the warning receiver.

3. The hazard alarm system of claim 1, wherein the warning device comprises a network interface device for receiving the warning alert message via an Internet.

4. The hazard alarm system of claim 1, wherein the warning alert message comprises a type of message;

wherein the system controller determines the type of the warning alert message; and

wherein the system controller determines whether to issue the alarm system alert based on the type of warning alert message.

5. The hazard alarm system of claim 1, wherein the warning alert message comprises a tag to indicate the at least one aspect of the warning alert message;

and

wherein the system controller determines whether to issue the alarm system alert based on the tag.

6. The hazard alarm system of claim 1, wherein the hazard alarm system comprises a plurality of notification appliances;

and

wherein the system controller determines which, of the plurality of notification appliances, to send the warning alert message to in order to issue the alarm system alert.

7. The hazard alarm system of claim 6, wherein the system controller determines which, of the plurality of notification appliances, to send the warning alert message to based on at least one of time of receipt of the warning alert message or type of the warning alert message.

8. The hazard alarm system of claim 1, wherein the warning alert message comprises a current warning alert message;

and

wherein the system controller determines whether to issue an alarm system alert based on analyzing a history of at least one stored warning alert message, the stored warning alert message being received prior to the current warning alert message.

9. The hazard alarm system of claim 8, wherein the system controller determines whether to issue an alarm system alert by comparing the stored warning alert message with the current warning alert message to determine if the stored warning alert message is different from the current warning alert message.

10. The hazard alarm system of claim 9, wherein the system controller determines whether to issue an alarm system alert by determining whether a threat level in the current warning alert message is greater than the threat level in the stored warning alert message.

11. The hazard alarm system of claim 1, wherein the system controller dynamically creates a content of the alarm system alert.

12. The hazard alarm system of claim 11, wherein the warning alert message received from the warning device comprises a dynamic message;

and

wherein at least a part of the alarm system alert created by the system controller is based on the dynamic message.

13. The hazard alarm system of claim 12, wherein at least a part of the alarm system alert created by the system controller is based on the dynamic message and based on a stored message;

and

wherein the notification appliance cycles between issuing the dynamic message and the stored message.

14. The hazard alarm system of claim 1, wherein the system controller determines when to issue the alarm system alert.

15. The hazard alarm system of claim 14, wherein the system controller determines to delay issuance of the alarm system alert.

16. A hazard alarm system for an area, the hazard alarm system for monitoring at least one aspect of the area, comprising:

a warning device for receiving a warning alert message from a source external to the hazard alarm system;

at least one device for monitoring the area; and

a system controller in communication with the warning device and receiving the warning alert message from the warning device, the system controller modifying operation of the at least one device based on the warning alert message received.

17. The hazard alarm system of claim 16, wherein the at least one device comprises a hazard detector that detects any of fire, heat, and smoke, the hazard detector in communication with the system controller and being separate from the warning device.

18. The hazard alarm system of claim 16, wherein the at least one device comprises an environmental control device for the area.

19. The hazard alarm system of claim 18, wherein the environmental control device comprises an HVAC system;

and

wherein modifying operation comprises modifying flow of air in the HVAC system based on the warning alert message received.

20. A method, in a hazard alarm system, for providing warnings, the method comprising:

detecting a warning alert message from a governmental organization;

determining whether to issue an alarm system alert based on at least one aspect of the warning alert message; and

providing, from a hazard alarm notification appliance, notification of the alarm system alert if it is determined to issued the alarm system alert.

21. The method of claim 20, wherein the warning alert message comprises a type of warning alert message;

and

determining whether to issue an alarm system alert based on at least one aspect of the warning alert message is based on the type of warning alert message

22. The method of claim 20, further comprising determining how to issue the alarm system alert.

23. The method of claim 22, wherein the hazard alarm system comprises a plurality of notification appliances;

and

wherein determining how to issue the alarm system alert comprises selecting a subset of the plurality of notification appliances to issue the alarm system alert.

24. The method of claim 23, wherein the notification appliance selected comprises an annunciator.

25. The method of claim 20, further comprising determining where to issue the alarm system alert.

26. The method of claim 25, wherein the hazard alarm system comprises a plurality of areas monitored;

and

wherein determining where to issue the alarm system alert comprises selecting a subset of the plurality of areas in which to issue the alarm system alert.

27. The method of claim 20, further comprising determining what to issue as the alarm system alert.

28. The method of claim 27, wherein determining what to issue as the alarm system alert comprises dynamically generating at least a part of the alarm system alert based on a message content in the warning alert message.

29. In a hazard alarm system for an area, the hazard alarm system for monitoring at least one aspect of the area, a method for providing alerts comprising:

detecting a warning alert message from a governmental organization; and

modifying operation of at least one device for monitoring the area based on the warning alert message received.

30. The method of claim 29, wherein the at least one device comprises an environmental control device for the area.

31. The method of claim 30, wherein the environmental control device comprises an HVAC system;

and

wherein modifying operation comprises modifying flow of air in the HVAC system based on the warning alert message received.
