Tyco EC-25 User manual

General
Description
TYCO Model EC-25 Extended Cover-
age Upright Sprinklers are UL Listed
standard response, extended cover-
age sprinklers for Storage Protection
(Area/Density) and FM Approved quick
response, extended coverage sprin-
klers for storage and non-storage ap-
plications. Their use is especially ad-
vantageous as a means of decreasing
the number of required sprinklers to
protect occupancies requiring an area/
density application of water.
These sprinklers offer a maximum
coverage area of 196 ft² (18,2 m²),
which is almost double the area of-
fered by standard coverage sprinklers
used for similar applications.
The Model EC-25 Sprinklers comply
with the criteria for the protection of
retail stores as described in the 2010
Edition of NFPA 13, Section 20.3.
Where the FM Approval is utilized, the
Model EC-25 Sprinkler has success-
fully undergone full-scale re testing at
FM Global for ceiling-only storage ap-
plications. When used in conformance
with applicable FM Global Property
Loss Prevention Data Sheets, the
Model EC-25 Sprinkler provides low
hydraulic demand, the spacing ad-
vantages of extended coverage, and
the obstruction benets of an upright
sprinkler.
For more information on applications
and benets of the Model EC-25 Sprin-
kler, refer to the available white papers
at www.tyco-re.com.
NOTICE
The Model EC-25 Sprinklers described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Pro-
tection Association, in addition to the
standards of any other Authorities
Having Jurisdiction (for example, FM
Global). Failure to do so may impair
the performance of these devices.
Owners are responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
with any questions.

Operation
The fusible link assembly is com-
prised of two link halves that are
joined together by a thin layer of sol-
der. When the rated temperature is
reached, the solder melts and the
two link halves separate, allowing the
sprinkler to activate and ow water.
Design Criteria
UL AND C-UL LISTING
CRITERIA
The Model EC-25 Extended Coverage
Upright Sprinklers (TY9128) are UL
and C-UL Listed for installation in ac-
cordance with the extended coverage
upright spray sprinkler requirements
of NFPA 13 or other applicable NFPA
standards when used in conjunction
with the following guidelines:
• Suitable for the protection of extra
hazard and high-piled storage occu-
pancies where area/density design
criteria are provided.
• Suitable for “unobstructed” or
“noncombustible obstructed”
construction.
• The Model EC-25 Sprinklers hav-
ing been specically tested and
listed for noncombustible obstruct-
ed construction are suitable for use
within trusses or bar joists hav-
ing noncombustible web members
greater than 1 inch (25.4 mm) when
applying the 4 times obstruction cri-
teria rule dened under “Obstruc-
tions to Sprinkler Discharge Pattern
Development”.
• The maximum coverage area per
sprinkler is 196 ft.² (18,2 m²).
• The maximum distance between
sprinklers is 15 feet (4,6 m) when the
coverage area does not exceed 144
ft.² (13,4 m²), and the maximum dis-
tance between sprinklers is 14 feet
(4,3 m) when the coverage area
does not exceed 196 ft.² (18,2 m²).
• The minimum distance between
sprinklers is 8 feet (2,44 m).
• The minimum ow requirement is
based on the design density applied
over the actual coverage area per
sprinkler.
For example: when sprinkler spacing
is 14 ft. x 12 ft. - 6 in. (4,3 m x 3,8 m) or
175 ft² (16,3 m²), and the design
density is 0.6 GPM/ft² (24,4 mm/
min), the sprinkler design ow rate
is 105 GPM (397 LPM) and the re-
quired design pressure is 17.4 psi
(1,2 bar).
• The minimum clearance between
the deector and the top of storage
is 36 inches (0,9 m). For clearances
of 36 inches (0,9 m) up to 48 inches
(1,21 m), the minimum design pres-
sure is 22 psi (1,52 bar). For clear-
ances of 48 inches (1,21 m) and
greater, the minimum design pres-
sure is established by the minimum
ow requirement. However, the
pressure can never be less than 7
psi (0,5 bar).
• Ordinary and intermediate tem-
perature rated Model EC-25 Sprin-
klers have been investigated for use
in high-piled storage occupancies
at the hydraulic demand normally
associated with high temperature
sprinklers. As such, the Model EC-
25 Sprinklers are listed storage
sprinklers having a K-factor greater
than 11.2 (161,4) and having ordi-
nary and intermediate temperature
ratings (that is, 165°F or 74°C and
214°F or 101°C). Consequently, the
Model EC-25 Sprinklers, in accor-
dance with NFPA 13, may be used in
conjunction with the density curves
for high temperature sprinklers.
• NFPA obstruction rules for Extended
Coverage Sprinklers must be utilized.
