1. A self-configuring alarm network, installed in a premises, comprising:
- a plurality of alarm network devices, each of which comprises;
processor means for communicating with said plurality of alarm network devices to dynamically establish a network of said plurality of alarm network devices,at least one sensor means for detecting the presence of a hazard condition, andalarm means for generating at least one alarm indication in response to detection of said presence of a hazard condition,wherein said processor means is responsive to a hazard detected by said at least one sensor means for communicating via said network of said plurality of alarm network devices to relay said hazard detection to said plurality of alarm network devices.

Abstract
The present self-configuring alarm network uses a decentralized (ad hoc or mesh) architecture that does not have a centralized “master” node. In this ad hoc network, any node is capable of behaving as if it were the “master node” by autonomously reporting the alarm event directly to all other nodes in the ad hoc network independent of where the alarm event occurred. The network of alarm devices, therefore, can spread the alarm indication to the entirety of the area covered by the network of alarm devices and can also differentiate between a general alarm indication and the locus of the alarm event.
