Described herein is an external fire protection system utilizing both fire hoses and fixed atomized water sprinklers. Water is supplied by either a local utility or static source pressurized by reciprocating or auxiliary electric engine employing high pressure/high volume pumps that are independent of any power grid outages. Both manual and local heat sensor detection are incorporated for automatic activation. The system also includes remote activation via any WiFi internet source (e.g., satellite) via a phone app to any programmable logic controller for continuous or water-saving intermittent operation.
