Fire deterrent system for structures in a wildfire hazard area

摘要

The fire deterrent system operates in a preemptive manner by detecting the impending approach of a wildfire within the vicinity of the structure to be protected. The system includes apparatus to identify the locus and direction of spread of a fire while it is outside of a defensive perimeter that encircles the structure and extends outward therefrom. The estimated time of arrival of the fire at the defensive perimeter is determined and the structure and surrounding vegetation sprayed a predetermined time in advance of the determined arrival of the fire. Prewetting the structure and surrounding vegetation reduces the probability of local fires caused by wind-borne embers and reduces the combustibility of these materials to assist conventional fire fighting efforts.
