FM Approved ceiling-level Storage
Sprinklers for storage occupancy
hazards and other similar high heat
release type fires. When compared
with other FM Approved Storage Sprin-
klers, the Model EC-25 Upright Sprin-
kler provides low hydraulic demand,
the spacing advantages of extended
coverage, and the FM Global obstruc-
tion benefits of an upright sprinkler.
Model EC-25 Upright Sprinklers should
be used in conformance with applica-
ble FM Global Property Loss Preven-
tion Data Sheets.
Hydraulic Design
To determine the hydraulic design for
the Model EC-25 Upright Sprinkler refer
to the applicable FM Global Property
Loss Prevention Data Sheet.
System Type
Wet pipe systems only
Sprinkler Spacing
The maximum coverage area per
sprinkler is 196 ft² (18,2 m²). The
minimum coverage area per sprinkler is
100 ft² (9,3 m²). The maximum distance
between sprinklers is 14 ft (4,3 m). The
minimum distance between sprinklers
is 10 ft (3,05 m).
Note: When a wall or obstruction
makes a minimum spacing of 10 ft
(3,05 m) impossible, consult FM Global
Property Loss Prevention Data Sheet
2.0 for applicable guidelines.
Sprinkler Location
Locate sprinklers with respect to
the ceiling/roof in accordance with
FM Global Property Loss Prevention
Data Sheet 2.0.
Obstructions
Follow the obstruction requirements
as detailed in FM Global Property Loss
Prevention Data Sheet 2.0.
Other Details
All other design details should be in
accordance with FM Global Property
Loss Prevention Data Sheet 2.0 as well
as any other applicable FM Global Data
Sheet.
NFPA 13 – Alternative System
Design (CMSA) Criteria
The TYCO Model EC-25 Extended Cov-
erage Upright Sprinklers (TY9128) have
successfully undergone large-scale
fire tests at FM Global to comply with
the current edition of NFPA 13. As such,
NFPA 13 may be utilized for design
options with the Model EC-25 Upright
Sprinklers for providing ceiling-only
protection.
This allows for the protection of Pallet-
ized, Single, Double, and Multiple Row
Open Racks. Protection is up to 30 ft
(9,1 m) of Cartoned, Unexpanded
Group A Plastic Commodities in a
maximum 35 ft (11 m) ceiling con-
dition with extended spacing up to
196 ft² (18,2 m²). This protection is
delivered while maintaining very rea-
sonable flow and pressure require-
ments. Pipe sizes as well as water
supply requirements can now be kept
to a minimum when compared to other
design methods for high piled storage
challenges.
