25.2 (360) K-factor (360) Upright Sprinkler
Extended Coverage
General
Description
The TYCO Model EC-25 Extended
Coverage (EC) 25.2K Upright Sprin-
kler is a UL Listed, standard response,
extended coverage Control Mode
Density Area (CMDA) sprinkler for
storage applications. It is also FM
Approved as a quick response,
extended coverage Control Mode
Density Area (CMDA) sprinkler and
as a Control Mode Specific Appli-
cation (CMSA) sprinkler, as well as
FM Approved for storage and non-stor-
age applications.
In addition, these sprinklers may be
used in accordance with the new
Chapter 21 of the 2013 edition of
NFPA 13. As such, tables 21.2.2 and
21.3.2 of NFPA 13 may be utilized for
design options. When used in accor-
dance with NFPA Chapter 21, smoke
vents and draft curtains are not required
as specified in the 2015 edition of the
International Building Code (IBC) and
International Fire Code (IFC) for CMSA
sprinklers with an RTI of 50 or less and a
design of 12 or fewer sprinklers.
These sprinklers offer a maximum cov-
erage area of 196 ft.² (18,2 m²), which
is almost double the area offered by
standard coverage sprinklers used for
similar applications.
The Model EC-25 Upright Sprinklers
comply with the criteria for the protec-
tion of retail stores as described in the
2013 Edition of NFPA 13, Section 20.3.
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
Installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Where the FM Approval is utilized, the
Model EC-25 Upright Sprinkler has
successfully undergone full-scale fire
testing at FM Global for ceiling-only
storage and non-storage applica-
tions. When used in conformance with
applicable FM Global Property Loss
Prevention Data Sheets, the Model
EC-25 Sprinkler provides low hydrau-
lic demand, the spacing advantages of
extended coverage, and the obstruc-
tion benefits of an upright sprinkler.
For more information on applications
and benefits of the Model EC-25 Sprin-
kler, refer to the available white papers
