The Specific Application Attic Sprinklers
must be installed in accordance with the
following instructions:
NOTES
Do not install any bulb type sprinkler if the
bulb is cracked or there is a loss of liquid
from the bulb. With the sprinkler held
horizontally, a small air bubble should be
present.
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7 to 14
ft.lbs. (9,5 to 19,0 Nm). A maximum of 21
ft.lbs. (28,5 Nm) of torque is to be used to
install 1/2" NPT sprinklers. A leak tight 3/4
inch NPT sprinkler joint should be
obtained with a torque of 10 to 20 ft.lbs.
(13,4 to 26,8 Nm). A maximum of 30
ft.lbs. (40,7 Nm) of torque is to be used to
install 3/4" NPT sprinklers. Higher levels
of torque may distort the sprinkler inlet with
consequent leakage or impairment of the
sprinkler.
Step 1. All Specific Application Attic
Sprinklers except the HIP must be
installed in the upright position with the
frame arms vertical. The deflector takes
into account the slope. The HIP sprinkler
is installed with the deflector parallel with
the slope of the hip. All Sprinklers must be
installed so the frame arms are parallel
with the branch line pipe.
Step 2. With pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting.
Step 3. Wrench tighten the sprinkler using
only the following wrenches:

Physical Characteristics
The Specific Application Attic Sprinklers
utilize a dezincification resistant (DZR)
bronze frame. The thermal sensitive
element is either a 3 mm bulb with a two-
piece brass and copper button assembly,
or a monel thermal sensitive link. The
sprinkler frame orifice is sealed with a
gasketed spring plate (Belleville Seal)
consisting of a beryllium nickel disc spring
that is sealed on both its inside and
outside edges with a Teflon
TM
gasket. The
compression screw is bronze, & the
deflector is brass.
General
Desc.
(Cont.)
situations require a pattern in only one
direction. Another use is when the framing
direction is parallel with the outside wall in
the hip area
(see figure 11). In this case,
the Single Directional would be used on
one side of the slope and standard
sprinklers would be used to protect the
other side. Be sure that it is installed
vertically, not angled with the slope, and
the correct model is used to compensate
for the slope.
The HIP Sprinkler
The HIP Sprinkler covers the area of the
hip in the attic. This is a slightly different
concept than the Back to Back or Single
Directional. The HIP Sprinkler is located
along the slope down the hip, and throws a
90
°
pattern toward the outside eaves. This
allows the water to “corner” the fire and
control it even at far distances. It does not
throw much water directly up or down the
hip but rather it throws most of the pattern
out to each side (90
°
) down the slope of the
roof and therefore can be spaced 6'-0"
(1,8m) to 3'-0" (0,9m) on center down the
slope without the danger of cold solder. To
use the HIP™ Sprinkler, the framing must
be perpendicular to the outside wall
(see
figure 12) and the maximum throw cannot
be over 28'-0" (8,5m) measured flat. It,
unlike the Back to Back and Single
Directional, is run with the deflector parallel
with the slope and there is only one model
with flows and pressures for two different
spacings.

& HIP - The
glass bulb contains a fluid which expands
when exposed to heat. When the rated
temperature is reached, the fluid expands
sufficiently to shatter the glass bulb, which
then allows the sprinkler to activate & flow
water.
BB1, BB2, BB3, SD1, SD2 & SD3 - The
fusible link assembly is comprised of two
link halves which are joined by a thin layer
of solder. When the rated temperature is
reached, the solder melts and the two link
halves separate, which then allows the
sprinkler to activate and flow water.
WARNINGS
The Specific Application Attic Sprinklers
described herein must be installed and
maintained in compliance with this
document, as well as with the applicable
standards of the National Fire Protection
Association, in addition to the standards of
any other authorities having jurisdiction.
Failure to do so may impair the integrity of
these devices.
The owner is responsible for maintaining
their fire protection system and devices in
proper operating condition. The installing
contractor or sprinkler manufacturer
should be contacted relative to any
questions.
