2-7 DISCHARGE NOZZLES
Discharge nozzles control the distribution of carbon dioxide into the protected area or onto the
protected equipment (or process). Kidde Fire Systems discharge nozzles are designed to
provide the proper combination of flow rate and discharge pattern to protect vital equipment
in a total-flooding manner or on a local application basis.
Kidde Fire Systems discharge nozzles are marked to identify the nozzle and show the nozzle's
equivalent single orifice diameter. The equivalent diameter refers to the orifice diameter of a
"standard" single orifice type nozzle having the same flow rate as the Kidde Fire Systems
nozzle.
The orifice code numbers indicate the equivalent single-orifice diameter in 1/32-inch
increments. A plus (+) symbol is used to indicate a 1/64-inch increment.
2-7.1 Multijet Nozzle, Type S
The type S multijet nozzles (listed in Table 2-27) have a female 1/2-inch NPT inlet connection
for attaching to the CO

distribution piping. Strainers are provided with nozzles having orifice
code numbers from 2 to 5+.
Type S nozzle sizes and styles are summarized in Table 2-27.
