Attic Spaces Greater Than 60 Feet (18,3m) up to 80 Feet (24,4m) Wide, (Ref. Figures 14 & 15)
Only 8.0 K, BB Sprinklers in conjunction with AP Sprinklers or Standard Spray Sprinklers can be used to protect attics up
to 80 feet (24,4 m) wide.
NOTE
Attics over 80 feet (24,4 m) wide must use Standard Spray Sprinklers throughout because Attic Sprinklers have not been
tested in this scenario.
For single ridge construction (Ref. Figure 14A & 14B), use 8.0K, BB Sprinklers to protect the center portion. AP Sprinklers
(Ref. Fig. 14A) or Standard Spray Sprinklers (Ref. Fig. 14B) are then used to protect up to 10 feet (3,1 m) of width at the
eaves beyond the maximum allowable 60 foot (18,3 m) span of the 8.0K, BB Sprinklers.
For hip roof construction (Ref. Figure 15), use 8.0K, BB Sprinklers in the center portion and HIP Sprinklers can be located
down the entire hip. AP Sprinklers or Standard Spray Sprinklers are then used to protect up to 10 feet (3,1 m) of width at
the eaves beyond the maximum allowable 60 foot (18,3 m) span of the 8.0K, BB Sprinklers, and the maximum allowable
horizontal coverage of the HIP Sprinklers.
