Sprinkler Layout – Adjacent Hip Criteria
Sprinkler Model
FL-SA/DS
Flow Rate
• 20 gpm
Distance Between Sprinklers
• Minimum 6 ft
• Maximum 8 ft
Distance From Eave To First Row (measured horizontally)
• Minimum 5 ft
• Maximum 20 ft
Deflector Distance Below Ceiling
• Install with deflector below bottom of top chord 1"
minimum to 4" maximum.
Sprinklers Adjacent To Hip Line
• All FL-SA/GAP Sprinklers directly adjacent to hip
line shall be 1 ft. to 3 ft. from hip line (as measured
perpendicular to hip line)
Installation
• Ensure that the sprinkler is installed with the
deflector parallel to the sloped roof above
• Sprinklers must be installed with the frame arms
perpendicular to the roof slope (see Figure 35).
• For obstruction criteria, see Obstruction section
within this data sheet.
Hydraulic Calculations
• See Hydraulic Design Section
FIGURE 15: ADJACENT HIP LAYOUT CRITERIA USING FL-SA/DS SPRINKLERS
NOTE
• If a flat sloped ceiling is present utilizing non combustible insulation, the insulation must completely fill the pockets
between the joists, and the insulation must be secured in place with metal wire netting or equivalent. The metal
wire netting is intended to hold the insulation in place should the insulation become wetted by the operation of the
sprinkler. Attic sprinklers have not been evaluated for use with spray foam insulation.
