Requirements
The Tyco®Ultra K17 (TY7153) Sprin-
klers with a 200°F/93°C temperature
rating may be installed in accordance
with NFPA 13 “Specific Application
Control Mode Sprinkler (for Storage
Use)” requirements to provide ceiling
only protection (i.e., no in-rack sprin-
klers) for high piled storage occupan-
cies (Solid-piled, palletized and rack
storage including but not limited to
Class I-IV and Group A plastics) using
the following criteria:
•astorageheightofupto25feet(7,6
m);
•a maximum ceiling height of 30 feet
(9,1 m);
•a minimum aisle width of 8 feet (2,4
m) for rack storage of Group A plas-
tic commodity stored from 20 feet to
25 feet (6,1to 7,6 m) and with ceiling
heights to 30 feet (9,1 m);
•a minimum deflector to top of stor-
age clearance of 36 inches (0,9m);
•a maximum coverage area of 100 ft2
(9,1 m2);
•a minimum coverage area of 80 ft2
(7,3 m2);
•NFPA spacing criteria for large drop
sprinklers, i.e.
12 feet (3,6 m) maximum for unob-
structed construction,
10 feet (3,0 m) maximum for rack
storage applications,
10 feet (3,0 m) maximum for ob-
structed construction, and
8feet(2,4m)minimum;
•NFPA deflector-to-ceiling distances
for large drop sprinklers;
•NFPA obstruction criteria for large
drop sprinklers;
•no additional column protection is
required;
•a hydraulic design of:
15 sprinklers at 10 psi (0,7 bar) for
Class I & II commodities, or
15 sprinklers at 22 psi (1,5 bar) for
Class III, IV, and cartoned or uncar-
toned unexpanded Group A and B
plastics; and,
•wet systems only (including preac-
tion systems that qualify as wet-pipe
systems)
FM Approval Requirements
TheTyco®16.8 K-factor, Ultra K17
(TY7153) Sprinklers may be installed
with the applicable “specific applica-
tion control mode” guidelines provided
byFactoryMutual.(FMguidelinesmay
differ from UL and C-UL Listing crite-
ria.)
Operation
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and flow water.
Installation
NOTICE
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 horizontal, a small air bubble
should be present.The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm).
The Ultra K17 Sprinklers must be in-
stalled in accordance with the follow-
ing instructions:
Step 1. With pipe thread sealant ap-
plied to the pipe threads, hand tighten
the Ultra K17 Sprinkler into the sprin-
kler fitting.
Step 2. Using the W-Type 8 Sprinkler
Wrench (Ref. Fig. 2) applied to the
sprinkler Wrench Flats (Ref. Fig. 1),
tighten the Ultra K17 Sprinkler into the
sprinkler fitting.
NOTICE
A leak tight 3/4 inch NPTsprinkler joint
should be obtained with a minimum to
maximum torque of 10 to 20 ft.lbs.
(13,4 to 26,8 Nm). Higher levels of
torque may distort the sprinkler with
consequent leakage or impairment of
the sprinkler.
