An air handler is disposed at the interior end of the inlet duct to provide air from outside the building to the air handler. A flame arrester is located at the exterior end of the inlet duct to prevent burning embers from entering the inlet duct. The fire protection system also includes an interior duct system for distributing air from the air handler through the building. Distribution vents in the interior duct system allow flow of air from the interior duct system to the interior of the building to raise the pressure in the building above the outside pressure. Exhaust vents to allow flow of air out of the building. Also, a method for fire prevention for a building exposed to a fire.
