Claim:
An outdoor fire prevention system for reducing the likelihood of fire damage while preserving water consumption, said outdoor fire prevention system comprising: a roof structure attached to a building; a plurality of first groups of water discharging assemblies situated at the existing roof structure; a plurality of second groups of water discharging assemblies situated at the existing roof structure; means for automatically distributing water to a target group of water discharging assemblies selected from each of said first and second groups of water discharging assemblies when a roof surface temperature of a target region of said roof structure is elevated above a maximum threshold roof surface temperature such that remaining ones of said water discharging assemblies remain at off positions and thereby reduce water consumption; a primary water shutoff valve in fluid communication with said automatic water distribution means, said primary water shutoff valve being adapted to receive and selectively transmit an external water supply to said automatic water distributing means; a primary conduit in fluid communication with said primary water shutoff valve, said primary conduit further being in fluid communication with said automatic water distributing means; and a controller communicatively coupled to said primary water shutoff valve, said controller generating and transmitting a user input signal based upon a user input to remotely interrupt the external water supply prior to reaching said first and second groups of water discharging assemblies; wherein each of said first groups of water discharging assemblies is located subjacent to each of said second groups of water discharging assemblies and comprises: first and second water discharging nozzles positioned at oppositely facing lateral edges of said roof structure; a plurality of first auxiliary conduits in fluid communication with said primary conduit as well as said first and second water discharging nozzles respectively; and a plurality of valves housed within a corresponding one of said first auxiliary conduits respectively, each of said valves being located downstream from an associated one of said first and second water discharging nozzles respectively; wherein one of said valves is a main valve situated upstream of remaining ones of said valves such that water is permitted to flow to said first and second water discharging nozzles while water is restricted from flowing to an adjacent group of said first groups of water discharging assemblies that is located downstream of said main valve.
