Abstract

A networked system of addressable alarms notifies citizens of conditions within a community, A control center is communicably linked via the network to alarm devices such as smoke detectors in controlled environments such as buildings in order to alert citizens of conditions outside of the controlled environment, which may be situations requiring an emergency response. The alarm devices may also be capable of sending local status information (e.g., fire alarms, security alarms, etc.) to the control center so that the control center can respond as necessary to any local emergencies.

Claims

1. A system for alerting a community, the system comprising;

a community-wide network;

a node in the network for individually addressing signaling devices connected to the network in response to an emergency condition in a predetermined geographic area; and

each signaling device located in a controlled environment and including a decoder for triggering a signaling generator of the device when an address from the node matches an address assigned to the signaling device.

2. The system of claim 1 wherein the signaling device is a smoke detector.

3. The system of claim 1 wherein the controlled environment is a building and the signaling device in the building includes a transmitter for transmitting a signal to a node in the community-wide network for alerting a public safety resource to a dangerous condition at the building.

4. The system of claim 3 wherein the signaling device is a smoke detector.

5. The system of claim 1 wherein the community-wide network includes a plurality of interconnected nodes of repeaters forming a mesh network for passing transmissions among the nodes to a destination signaling device whose address matched the address in the transmission.

6. The system of claim 5 wherein the mesh network is one of a Wi-Fi mesh network and a ZigBee mesh network.

7. The system of claim 1 wherein the community-wide network is one of a WiMAX system and a cellular network.

8. The system of claim 1 including signaling devices mounted in uncontrolled environments for generating alarms for alerting a general populace of the community.

9. The system of claim 1 wherein the community-wide network is a wireless network that connects to the Internet.

10. A detector and alarm for a building comprising;

a sensor for detecting a dangerous condition local to the building;

a receiver for receiving a signal including data indicating a dangerous condition outside of the building;

a decoder for comparing the data in the signal to expected data and generating a trigger signal when the comparison indicates a match; and

an annunciator responsive to (1) the sensor for generating a first audible signal for signaling the local dangerous condition has been detected and (2) the trigger signal for generating a second audible signal for signaling a dangerous condition outside of the building.

11. The detector and alarm of claim 10 wherein the receiver is one of a Wi-Fi receiver, a WiMAX receiver, a cellular receiver, an Ethernet receiver and a ZigBee receiver and the signal is one of a Wi-Fi signal from a Wi-Fi mesh network, a WiMAX signal, a cellular signal from a cellular network, an Ethernet signal and a ZigBee signal from a ZigBee mesh network.

12. The detector and alarm of claim 10 including a transmitter triggered in response to detection of the local dangerous condition by the sensor and a Wi-Fi signal generated by the transmitter including an address of a destination in a network.

13. The detector and alarm of claim 10 wherein the sensor is one of a smoke detector and a carbon dioxide detector.

14. The detector and alarm of claim 10 including a pluggable port for receiving an encapsulated unit including the receiver.

15. A method of alerting a community to a dangerous condition:

sensing the dangerous condition outside a controlled environment within a community of controlled environments connected to a communications network;

transmitting over the network a signal whose format allows for one of the controlled environments to be addressed; and

triggering an alarm at the controlled environment within the community of controlled environments when the signal is determined to be addressing the controlled environment.

16. The method of claim 15 wherein the format of the signal has the ability to alternatively address individual ones of the controlled environments or predetermined groupings of the controlled environments.

17. The method of claim 15 wherein the alarm is a first alarm and the method includes detecting a dangerous condition within the controlled environment and triggering a second alarm.

18. The method of claim 17 wherein the first and second alarms are recognized by occupants of the controlled environment to warn of different conditions.

19. The method of claim 15 wherein the network for transmitting the signal includes is one of a Wi-Fi network, a cellular network, an Ethernet network and a ZigBee network

20. The method of claim 15 wherein the network is a wireless network.

21. The method of claim 15 wherein the dangerous condition is severe weather.

22. The method of claim 15 including determining whether controlled environments within the network are exposed to the dangerous condition.

23. A method of alerting a community to a community-wide dangerous condition, sensing the dangerous condition;

transmitting a signal with data indicating the existence of the dangerous condition;

receiving the signal at a mobile signaling device located in a predetermined geographic area;

comparing the data in the signal to expected data for indicating the presence of a dangerous condition in the community; and

triggering an alarm when the data in the received signal matches the expected data.

24. The method of claim 23 including detecting a dangerous condition within a building and triggering an alarm.

25. The method of claim 24 wherein the alarm signaling the community-wide dangerous condition is different from the alarm signaling a dangerous condition within the building.

26. The method of claim 23 wherein transmitting the signal includes routing the signal to the signaling device over one of a Wi-Fi network, a cellular network, an Ethernet network and a ZigBee network.

27. The method of claim 23 wherein the signal is compatible for transmission over a wireless network.

28. The method of claim 23 wherein the community-wide dangerous condition is severe weather.

29. The method of claim 23 including determining if a signaling device is located in a predetermined geographic area.
