NOZZLESKidde discharge nozzles provide the proper flow rate ofHalon 1301 desired, and their unique design provides aturbulence-discharge of the gas to provide an optimizeddiffusion of the gas in the air. Two basic configurationsare available:1.180" Fan nozzle. See Figure 10.2.360° Split fan nozzle. See Figure 11.ACCESSORIESIf a cylinder is disconnected for replacement, elbowcheck valves (See Figure 12), installed between theflexible loop and the manifold, ensure the safety ofpersonnel. This valve will prevent the pressurized gas inthe manifold from entering the flexible loop if the loop isnot pressurized.Pressure operated trips, Figure 13, and switches, Figure14, isolate the rest of the plant while the fire is beingextinguished. Trips, operated by the pressure of Halon1301 in the piping, permit the closing of doors, windows,dampers, and other openings. The fire is preventedfrom spreading and damaging the rest of the plant.Pressure operated switches, also operated by gaspressure, shut off machines, ventilating fans, and otherelectric equipment when the system operates.Kidde offers, as an extra, a simplified weighingarrangement for weighing cylinders in place withoutdisconnecting them from the cylinder manifold. (Figure15) The weighing bar and weighing bar bracket aresupplied as part of this simplified weighing arrangement.These part are drilled and cut to proper length so thatthey are easily fastened to the cylinder framing. Thescale gives a direct reading of the weight of the cylinder.Because of a 10 to 1 ratio on the scale beam a pull of 15lbs. on the scale hook will record 150 lbs. on the scale.8
