For SD Sprinklers
(Single Directional)
• Determine the throw needed.
• As the 400 ft
2
(37, 2 m
2
) is not a fac-
tor with the SD Sprinklers, the max-
imum spacing is 6 feet (1,8 m) and
the minimum is 4 feet (1,2 m) (Ref.
Figures 2 & 11). (The reason 400 ft
2
is not an issue with the single di-
rectional is because, at its max-
imum spacing, 6 feet [1,8 m] on
center / covering 40 feet [12,2 m]
flat / a 12:12 slope / and the throw
being 56.5 feet [17,2 m], the 400 ft
2
[37,2 m
2
] maximum would not be
exceeded.)
• Avoid obstructions as shown in Fig-
ure 16. If necessary, add Model AP
Sprinklers or Standard Spray Sprin-
klers to maintain coverage around
obstructions.
For HIP Sprinklers
• Verify framing direction is perpen-
dicular to outside wall (Ref. Figure
12). If not, cover that area with AP
Sprinklers or Standard Spray Sprin-
klers (Ref. Figure 13)
• From the intersection of the top of
the hip and the ridge, the maximum
distance down the slope of the hip
is 3 feet (0,9 m). Start the layout with
the first sprinkler as close to that
point as possible, but no further,
while staying 6 inches (152,4 mm)
away from the face of the truss-
es. Remember the slope of the hip
is not equal to the slope of the roof
from the ridge to the outside wall.
Continue to space sprinklers down
the hip at a maximum of 6 feet (1,8
m) on center as measured along the
slope of the hip. When the bottom
of the hip is encountered, the last
sprinkler must be within 7-1/2 feet
(2,3 m) of the outside wall as mea-
sured flat (plan view). If this pipe is
“cut to fit”, remember to account
for the different slopes of the hip
and the roof, as well as distances
measured along the slope verses
horizontal in plan view must be ac-
counted for.
• Avoid obstructions as shown in Fig-
ure 16. If necessary, add Model AP
Sprinklers or Standard Spray Sprin-
klers to maintain coverage around
obstructions.
Care and
Maintenance
The TYCO
Specific Application Sprin-
klers for Protecting Attics must be
maintained and serviced in accor-
dance with this section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, obtain permission to shut
down the affected fire protection sys-
tem from the proper authorities and
notify all personnel who may be affect-
ed by this action.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and devic-
es in compliance with this document,
as well as with the applicable stan-
dards of the National Fire Protection
Association (e.g., NFPA 25), in addition
to the standards of any other authori-
ties having jurisdiction. Contact the in-
stalling contractor or product manu-
facturer with any questions.
Automatic sprinkler systems should
be inspected, tested, and maintained
by a qualified Inspection Service in
accordance with local requirements
and/or national code.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or otherwise
altered after leaving the factory. Modi-
fied sprinklers must be replaced.
Over-heated solder type sprinklers
must be replaced. Bulb-type sprin-
klers that have been exposed to cor-
rosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid dam-
age to the sprinklers before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be
replaced. Also, replace any sprinkler
that has a cracked bulb or that has
lost liquid from its bulb. (Refer to In-
stallation Section.)
