A system for remote detection of a fire condition includes a plurality of remote sensors and a central hub connected to each sensor to create a localized network capable of detecting changes in environmental conditioned within a geographic area defined by the locations of the sensors. The sensors may be configured to detect conditions such as changes in temperature, levels of carbon dioxide, smoke or other fire related particulates and report sensor readings back to the connected hub. The hub processes received sensor data from each sensor and generates an alert if the processed data meets any predetermined condition such as one associated with a fire. The alert may be transmitted to a tracking station with a geographic indication of where the alert was generated and a drone may be sent to the location of the geographic indication to acquire additional data to help determine if further action is required.

The plurality of extinguisher modules forms a wireless communication link between: a) the plurality of extinguisher modules, and, b) with an appropriate authority. When triggered by fire, the individual extinguisher module: c) releases a fire extinguishing chemical; and, d) transmits an alert message to both the appropriate authority and to the individual extinguisher modules remaining in the plurality of extinguisher modules containing the GPS coordinates of the transmitting individual extinguisher module. Each selected individual extinguisher module compares the GPS coordinates of the selected individual extinguisher mode to the GPS coordinates of the module alert message. If the span of the distance between the two coordinates is less than a previously determined span of distance, than the selected individual extinguisher module releases a fire retardant chemical.
