General
Description
The TYCO Model EC-25, Extended
Coverage 25.2K Upright Sprinkler
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 CMDA sprinkler
and as a Control Mode Specific Appli-
cation (CMSA) sprinkler, as well as
FM Approved for storage and non-stor-
age applications.
When used in accordance with
National Fire Protection Association
(NFPA) 13, smoke vents and draft cur-
tains 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 ft² (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 pro-
tection of retail stores as described in
NFPA 13.
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 Upright Sprinkler provides low
hydraulic demand, the spacing advan-
tages of extended coverage, and the
obstruction benefits of an upright
sprinkler.
For more information on applica-
tions and benefits of the Model EC-25
Upright Sprinkler, refer to the available
White Papers at www.tyco-fire.com.

Operation
The fusible link assembly is com-
prised 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 acti-
vate and flow water.
