Model EC-25
Extended Coverage Area Density Sprinklers
25.2 K-factor
General
Description
The Model EC-25 Extended Coverage
Upright Sprinklers (Ref. Figure 1) are
“Control-Mode Extended Coverage
Sprinklers” having a nominal K-factor
of 25.2. Their use is especially advantageous as a means of decreasing the
number of required sprinklers to protect occupancies requiring an
area/density application of water.
These sprinklers offer maximum coverage areas of 14 feet by 14 feet (196
sq. ft.) which is almost double that of
standard coverage sprinklers used for
similar applications.
The EC-25 Sprinklers comply with the
criterion for the protection of retail
stores as described in the 2002 edition
of NFPA 13, Section 12-7.2
Where the FM Approval is utilized, the
EC-25 has successfully undergone
full-scale fire testing at FM for use under obstructed ceiling conditions for
area/density design applications. This
testing has demonstrated that the
Model EC-25 at its extended coverage spacings can be installed using
all other standard coverage sprinkler criteria. As such, they are acceptable for all currently recognized
area/density applications.
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and installation of sprinkler systems and components. Improper handling and installation can permanently damage
a sprinkler system or its components and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Applications for the Model EC-25
Sprinklers are expanding beyond the
current testing. For information regarding additional research fire tests that
may be acceptable to an Authority
Having Jurisdiction please contact the
Technical Services Department.
WARNINGS
The Model EC-25 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 (e.g., FM Global). Failure to do so may impair the performance of these devices.

The fusible link assembly is comprised
of two link halves that are joined together by a thin layer of solder. When
the rated temperature is reached, the
solder melts and the two link halves
separate allowing the sprinkler to activate and flow water.
bar), and a K-factor of 25.2 (363 metric) is to be used for hydraulic calculations. As for all area/density sprinklers,
the hydraulic design for the Model EC25 sprinklers should be based on the
design density applied over the actual
area of coverage per sprinkler.
Design
Criteria
For example: when sprinkler spacing is
14 feet by 12 feet - 6 inches (4,3 x 3,8
m) or 175 ft2 (16,3 m2), and the design
density is 0.6 gpm/ft2 (24,4 mm/m), the
sprinkler design flow rate is 105 GPM
(397 LPM) and the required design
pressure is 17.4 psi (1,2 bar).
FM APPROVAL CRITERIA
3. System Type: Wet-pipe, dry-pipe,
or preaction systems are acceptable.
The Model EC-25 Extended Coverage
Upright Sprinklers (SIN TY9128) are
FM Approved to be utilized in accordance with the following guidelines:
1. Application: The Model EC-25
Extended Coverage Upright Sprinklers may be used to protect any occupancy for which there is an area/density design criterion up to 11.2
K-Factor standard spray (controlmode area/density) sprinklers specified in FM Global Data Sheets. The
Model EC-25 Sprinklers are not approved for use in control-mode specific
application (e.g. large-drop) or suppression-mode (ESFR) protection designs.
2. Hydraulic Design: Area/density designs should be the same as those for
11.2 K-Factor standard spray (controlmode area/density) sprinklers when a
separate 11.2 K-Factor standard spray
(control-mode area/density) sprinkler
design criteria is provided. Otherwise
use the same design criteria as 5.6 or
8.0 K-Factor standard spray (controlmode area/density) sprinklers. The
minimum design pressure is 7 psi (0,5
4. Sprinkler Spacing: The maximum
area of coverage per sprinkler is 196
sq. ft. (18,2 sq. m). The minimum area
of coverage per sprinkler is 100 sq. ft.
(9,3 sq. m). The maximum distance
between sprinklers is 14 feet (4,3 m).
The minimum distance between sprinklers is 10 feet (3,05 m).
Exception: When a wall or obstruction
makes a minimum spacing of 10 feet
(3,05) impossible between the line of
sprinklers along the wall and the next
adjacent line of sprinklers, the minimum distance from the sprinklers located along the wall or obstruction to
the sprinklers located on the adjacent
row can be a minimum of 7 feet (2,13
m). In this case the sprinklers located
along the wall or obstruction must be
hydraulically calculated for a 100 sq. ft.
(9,3 sq. m) coverage area or their actual coverage area, whichever is
greater.
5. Sprinkler Location: Locate sprinklers with respect to the ceiling/roof in
accordance with Section 4-6.4 of FM
Global Data Sheet 2-8N.
Exception: Exception #4 to Section
4-6.4.1.2 of FM Global Data Sheet
2-8N does not apply to extended coverage control mode sprinklers. For obstructed construction, when the structural members are deeper than 12
inches (300 mm) and spaced less than
42 inches (1050 mm) on center, install
sprinklers in every bay.
6. Obstructions: Follow the obstruction requirements for standard spray
(control-mode area/density) sprinklers
in Section 4-6.5 of FM Global Data
Sheet 2-8N.
7. Other Details: All other design details should be in accordance with FM
Global Data Sheet 2-8N, as well as any
other applicable FM Global Data
Sheet.
UL AND C-UL LISTING CRITERIA
The Model EC-25 Extended Coverage
Upright Sprinklers (SIN TY9128) are
UL and C-UL Listed for installation in
accordance 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 occupancies where area/density design
criterion are provided.
• Suitable for “unobstructed” or “noncombustible obstructed” construction.
• The Model EC-25 Sprinklers having
been specifically tested and listed
for noncombustible obstructed construction are suitable for use within
trusses or bar joists having noncombustible web members greater

than 1 inch (25.4 mm) when applying
the 4 times obstruction criteria rule
defined under “Obstructions to
Sprinkler Discharge Pattern Development”.
Care and
Maintenance
The Model EC-25 must be maintained
and serviced in accordance with the
following instructions:
• The maximum area of coverage per
sprinkler is 196 sq. ft. (18,2 sq. m).
The maximum distance between
sprinklers is 14 feet (4,3 m). The
minimum distance between sprinklers is 8 feet (2,44 m).
• The minimum flow requirement is to
be based on the design density applied over the actual area of coverage per sprinkler.
For example: when sprinkler spacing is 14 feet by 12 feet - 6 inches
(4,3 x 3,8 m) or 175 ft2 (16,3 m2), and
the design density is 0.6 gpm/ft2
(24,4 mm/m), the sprinkler design
flow rate is 105 GPM (397 LPM) and
the required design pressure is 17.4
psi (1,2 bar).
• The minimum clearance between
the deflector 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 pressure is 22 psi (1,52 bar). For clearances of 48 inches (1,21 m) and
greater, the minimum design pressure is established by the minimum
flow requirement (however, the
pressure can never be less than 7
psi).
• The ordinary and intermediate temperature rated EC-25 Sprinklers
have been investigated for use in
high-piled storage occupancies at
the hydraulic demand normally associated with high temperature
sprinklers. As such, the EC-25 sprinklers are listed storage sprinklers
having a K-factor greater than 11.2
and having ordinary and intermediate temperature ratings (i.e., 165F
and 214F). Consequently, the EC25 Sprinklers, in accordance with
the 2002 edition of NFPA 13, may be
used in conjunction with the densitiy
curves for high temperature sprinklers specified in Chapter 12 of the
2002 edition of NFPA 13.
