The function of the Discharge Nozzle, in a fire extinguishing system, is to distribute the Clean Agent in a uniform, pre-determined pattern and concentration. The nozzles are designed to complete the discharge of Clean Agent in 10 seconds, or less, when installed within the design limitations of the Installation Instruction Manual. Discharge Nozzles are available in sizes of 1/4, 3/8, 1/2, 3/4 , 1" , 1-1/4", 1-1/2" and 2".Each discharge nozzle comes in two configurations: 180 and 360 degree distribution patterns. As an option, deflector plates are available where sensitive ceiling tiles must be protected. Discharge Nozzles are made of aluminum with female pipe threads. Discharge Nozzle orifice sizes are determined by hydraulic flow calculations. All nozzles are rated for a maximum hazard height of 16 feet. If hazards exceed 16 feet in height, a second tier of nozzles must be used.
