System Design Procedure
Gable Style Roof
Option 1: Ridge Sprinklers Only
• When utilizing this option Series FL-SA/RE sprinklers
are used to protect the entirety of the attic space.
The span of the attic is measured along the floor
(or ceiling of floor below) of the attic space from
the peak to the intersection of the bottom of the
top chord of the roof joist and the non-combustible
insulation or floor joist on the floor (or ceiling of
floor below). The span is twice the longer of the two
measured spans. (See Figure 6)
• The maximum span which can be protected by a
single line of FL-SA/RE sprinklers at the peak is a
total span of 24 ft or a maximum half span of 12 ft.

Option 2: Ridgeline Sprinklers/Eave
Sprinklers (FL-SA/RE)
• This approach utilizes the FL-SA/RE sprinklers at the
Ridgeline and downslope covering to the eave. (See
Figure 10 for dimensional limitations)
Figure 9B
Option 3: Ridgeline Sprinklers with Downslope
Sprinklers
• The maximum span of this approach is 72 ft or a
half span of 36 ft. as measured horizontally. (See
Figure 10 and Figure 11 for dimensional limitations)
