Sprinkler Selection
Single Slope Roof Option 1:
FL-SA/DS Sprinklers at the Highpoint Only
• When utilizing this option, Model FL-SA/DS sprinklers
are used to protect the entire width of the attic space
from the eave to the vertical barrier of the single slope.
The span of the attic is measured along the floor (or
ceiling of floor below) of the attic space from the
peak/vertical barrier to the intersection of the top
chord and bottom chord of the roof trusses. See
Figure 4a and Figure 4b.
• The maximum span that can be protected by a single
line of FL-SA/DS sprinklers at the peak is 16 ft or 30 ft
(measured horizontally from the sprinkler to eave).
• See Figure 11A and Figure 11B for detailed sprinkler
layout criteria.
Single Slope Roof Option 2:
FL-SA/DS Sprinklers at the Highpoint and Downslope
• When utilizing this option, Model FL-SA/DS sprinklers
are used to protect the entire width of the attic space
from the eave to the vertical barrier of the single
slope. 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 top chord
and bottom chord of the roof trusses. See Figure 4a
and Figure 4b.
• The maximum span that can be protected by two
lines of FL-SA/DS sprinklers at the peak is 32 ft +
