5.0 PERFORMANCE (CONTINUED)

Sprinkler Layout – Under-Hip Criteria: Framing Members Parallel To Roof Slope

Sprinkler Model

• FL-SA/GAP

Flow Rate

• 20 gpm

Distance From Eave to First Row (measured horizontally)

• Minimum 5 ft
• Maximum 12 ft

Maximum Distance Between Sprinklers

• See Figure 12

Deflector Distance Below Ceiling

• Install with deflector below bottom of top chord 1"

minimum to 3" maximum

Sprinkler at Apex

• A FL-SA/GAP Sprinkler must be installed between 1

ft. to 5 ft. down from the intersection of the ridgeline
and hip lines (Apex)

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.

• For obstruction criteria, see Obstruction section

within this data sheet.

Hydraulic Calculations

• See Hydraulic Design Section

FRAMING MEMBERS PARALLEL TO ROOF SLOPE USING FL-SA/GAP

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.
