FIGURE 20-A-3. BB AND SD SPRINKLERS
• Wet Systems — Calculate the most de-
manding ve BB Sprinklers plus two SD
Sprinklers.
• Dry Systems — Calculate the most de-
manding seven BB Sprinklers plus up to two
SD Sprinklers (see adjacent gure).
FIGURE 20-A-4. SD SPRINKLERS
• Wet Systems — Calculate the most de-
manding five SD Sprinklers.
• Dry Systems — Calculate the most de-
manding nine SD Sprinklers (see adja-
cent figure).
FIGURE 20-A-5. SD AND HIP SPRINKLERS
• Wet Systems — Calculate the most de-
manding ve sprinklers.
• Dry Systems — Calculate the most demand-
ing nine sprinklers with a maximum of seven
to be SD Sprinklers (see adjacent gure).
FIGURE 20-A-6. HIP SPRINKLERS
• Wet Systems — Calculate the most de-
manding ve sprinklers (see adjacent g-
ure).
• Dry Systems — Calculate the most de-
manding nine sprinklers.
