Abstract
A fire detection and suppression system includes a wireless mesh network and a controller. The wireless mesh network includes of a plurality of wireless mesh nodes distributed throughout the building. The wireless mesh nodes transmit and receive wireless signals during a baseline time period and record a baseline set of signal characteristics and transmit and receive the wireless signals during a second time period after the baseline time period and record a second set of signal characteristics. The controller is configured to determine that the second set of signal characteristics are abnormal relative to the baseline set of signal characteristics as a result of a fire within the building degrading the wireless signals during the second time period. A fire is detected by the controller based on these signals and corrective action is initiated in response to detecting the fire within the building.
