SPRINKLERS & STANDARD SPRIN-

MENTALIZATION
Calculate the Attic Sprinkler demand
as described in Part A-1 thru A-6 or
Part C-1 thru C-4, and then calculate
the Standard Spray Sprinklers per
NFPA 13. Use the most demanding
calculation (see adjacent figure).

SPRINKLERS & STANDARD SPRAY
SPRINKLERS IN A DORMER, AT A
CROSS, AT A HIP, OR AT AN ELL
Where the quantity of standard spray
sprinklers in each dormer, cross, or
ell is four or less (see adjacent figure)
and all of the dormers, crosses and
ells meet the maximum four standard
sprinkler criteria, calculate the At-
tic Sprinkler demand as described in
Part A-1 thru A-6 or Part B-1 thru B-4,
plus up to two of the most demand-
ing standard spray sprinklers in the
dormer, cross, or ell that is adjacent to
the Attic Sprinklers that are being in-
cluded in the demand calculation.
Where the quantity of standard spray
sprinklers in any dormer, cross, or ell
is greater than four, refer to Figure
C-3.
