Layout Criteria – Eave
Sprinkler Model
• FL-SA/GAP
Flow Rate
• 20 gpm
Distance Between Sprinklers Perpendicular To Slope
• Minimum 6 ft
• Maximum 8 ft
Distance to Attic Eave
• Minimum 4 ft
• Maximum 12 ft
Minimum Distance From FL-SA/BB Sprinkler (Measured
Along The Slope)
• Minimum 21 ft (Located in Adjacent Channel)
Deflector Distance Below Ceiling
• Install with deflector below bottom of top chord 1"
minimum to 3" maximum.
Installation
• When installed for Eave protection, the FL-SA/GAP
Sprinkler has a zone of protection of 12 ft. in the
downslope direction to the eave (measured on the
horizontal) and 8 ft. wide (4 ft. laterally to either
side of the sprinkler). There is no zone of protection
allowance "upslope" of the FL-SA/GAP sprinklers
when used along eaves in conjunction with the FL-
SA/BB sprinklers upslope.
• Ensure that the sprinkler is installed with the
deflector parallel to the sloped roof above.
• Centerline of sprinkler must be a minimum of 6"
laterally from face of truss (See Figure 28).
• Must be offset at least one channel laterally from
any upslope sprinkler.
• Sprinklers must be installed with the frame arms
perpendicular to the roof slope.
• For obstruction criteria, see Obstruction section
within this data sheet.
• When installed under a flat sloped ceiling
(noncombustible insulation filled joist channels),
maximum deflector to ceiling distance is the same
as maximum distance below bottom of top chord.
Distance to be measured to bottom of insulation.
Hydraulic Calculations
• See Hydraulic Design Section
FL-SA/GAP SPRINKLERS MUST BE
OFFSET AT LEAST ONE CHANNEL
FROM FL-SA/BB SPRINKLERS
UPSLOPE
FIGURE 10: EAVE LAYOUT CRITERIA
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.
