Beschreibung
Zusammenfassung:	A ceiling ventilation hood and fire protection system includes a ceiling ventilation hood, the ceiling ventilation hood defining an upper plane and a lower plane with a filter disposed between the upper and lower planes, and at least two nozzles each having an outlet defining a discharge axis with the outlet disposed in the ceiling ventilation hood between the upper and lower planes to provide overlapping protection of a hazard zone. Each of the nozzles define a spray pattern to effectively address a fire within the hazard zone independent of airflow through the filter. The outlets of the at least two nozzles are positioned at least 54 inches above the hazard zone.
