3-3.7.12 DISCHARGE NOZZLES
The 180° and 360° discharge nozzles are designed to
provide the proper flow rate and distribution of FM-200
to flood a hazard area. The 180° nozzle is engineered to
provide a 180° discharge pattern for sidewall applica-
tions. The 360° nozzle offers a full 360° discharge pat-
tern for installations where nozzles are located in the
center of the hazard. See Figures 3-36 and 3-37 and
Tables 3-17 and 3-18 for further information.
