Installation
The Specific Application Attic Sprinklers for Protecting Attics
must be installed in accordance with this section. The
FL-SA/RE and FL-SA/DS Specific Application Attic
Sprinklers comprise an overall protection scheme which
takes into account strategic positioning for activation
sensitivity while providing unique distribution characteristics
specifically designed for attic construction.
The protection methodology utilizing these sprinklers has
been full scale fire tested in the built attic environment.
As such, they must be installed in accordance with the
guidelines set forth within this data sheet. The NFPA 13
Density/Area prescriptive spacing requirements do not
apply as these sprinklers are not bound by the NFPA 13
"S x L Rules". The positioning and spacing requirements
of this data sheet take precedence over any other
prescriptive requirements that may exist in NFPA 13.
To install the Specific Application Attic Sprinklers, the
following steps shall be taken:
Step 1.
Sprinklers must be oriented correctly as follows:
• Series FL-SA/RE Sprinklers
• At horizontal ridge (peak) – installed in the upright
vertical position with deflector parallel to the ceiling
below (i.e. sprinkler centerline perpendicular to
the ridgeline).
• Near eave or under hip type roofs – installed in
the upright position with deflector parallel to roof
deck (i.e. sprinkler centerline perpendicular to
the roof slope).
• Series FL-SA/DS Sprinklers
• These sprinklers are installed downslope from a
ridgeline/peak (See FIGURE 11). Installed in the
upright position with deflector parallel to roof
deck (i.e. sprinkler centerline perpendicular to
the roof slope).
Step 2.
With pipe thread sealant applied to the pipe threads,
hand tighten the sprinkler into the sprinkler fitting.
NOTE
• Do not grasp the sprinkler by the deflector.
Step 3.
Wrench-tighten the sprinkler using only the
appropriate wrench. Wrenches are only to be applied to
the sprinkler wrench flats or wrench hex, as applicable.
NOTE
• Do not apply wrench to frame arms.
