Abstract: An automated roof sprinkler fire suppression system is disclosed. The system responds to heat and smoke around an exterior perimeter of the structure and supplies pressure during low municipal pressures without depleting fire hydrant pressures. The system includes multiple sprinkler heads disposed on a roof of the structure and optional additional sprinkler heads on a sidewall of the structure. A conduit communicates a water source with the multiple sprinkler heads to douse the roof and exterior of the building with water to prevent heat and embers from igniting the structure.
