IntroductionTyco Fire Protection Products developed, introduced, and improved the revolutionary technology of Extended Coverage sprinklers for Extra Hazard and Storage Occupancies. The TYCO Model EC-25 Sprinkler provides the complete package for the higher density, extended coverage requirements of the fire sprinkler industry. The Model EC-25 Sprinkler is a “Control-Mode Extended Coverage Sprinkler” for Extra Hazard and High Piled Storage occupancies in accordance with NFPA 13 (2002 and later editions) and a “Storage Sprinkler” in accordance with FM Global Data Sheet 8-9. Its use is especially advantageous as a means of protecting occu-pancies requiring an density/area application of water while providing better fire protection than standard coverage sprinklers.

BenefitsKey benefits of the Model EC-25 Sprinkler include lower installed cost and better fire protection when com-pared to standard coverage sprinkler systems. These benefits are provided by:•Fewer opened sprinklers and fewer consumed pallets than K-8.0 (115), K-11.2 (160), and K-16.8 (240)

standard coverage sprinklers as shown in full-scale fire tests performed at UL•Fewer branch lines and fewer sprinklers as a result of the extended coverage area•Lower operating pressures in accordance with the S x L Spacing Rules defined by NFPA 13, Section 8.5.2•Lowest hydraulic system demand provided in FM Global Property Loss Prevention Data Sheet 8-9,

Better Fire ProtectionNew fire protection technologies are tested against baseline performance. Baseline tests for virtually all NFPA 13 density/area applications for high piled storage were performed with K-5.6 (80) sprinklers in the early 1970s. Current laboratory protocol includes more stringent pass/fail criteria than existed for these base-line tests. New technologies such as the Model EC-25 Sprinkler must duplicate the same testing with equal or better results.The following table shows fire test results for K-5.6 (80) and K-11.2 (161) standard coverage sprinklers spaced at 100 ft2 (9,3 m2) versus Model EC-25 Sprinklers spaced at 196 ft2 (18,2 m2).

Testing a higher fire risk, the following table compares K-8.0 (115) and K-11.2 (161) standard coverage sprin-klers spaced at 80 ft2 (7,4 m2) with the Model EC-25 Sprinkler spaced at 196 ft2 (18,2 m2).

As you can see from Table 2, in protecting Group A Plastic Commodities, the Model EC-25 Sprinkler returned results similar to those shown for Class II Commodities (Table 1). Specifically, the Model EC-25 Sprinkler:

•activated fewer sprinklers, •operated at lower pressures, and•maintained lower temperatures.

When comparing a larger K-factor sprinkler such as the K-16.8 (242) standard coverage sprinkler spaced at 100 ft2 (9,3 m2) with the Model EC-25 Sprinkler spaced at 196 ft2 (18,2 m2), the Model EC-25 Sprinkler pro-vides better fire protection even at the minimum operating pressure.

[1] At the minimum required pressure of 7 psi (0,48 bar), the Model EC-25 Sprinkler flows 67 GPM (253,6 LPM). This flow, over a coverage area of 100 ft2 (9,3 m2), results in an actual density of 0.67 GPM/ft2 (27,2 mm/min).

As shown in Table 3, the Model EC-25 Sprinkler once again outperformed standard coverage sprinklers with the following consistent results:

•activated fewer sprinklers, •consumed the same or the lowest number of pallets even at a pressure of 7 psi (0,48 bar),•operated at lower pressures, and•maintained lower temperatures.

Comparing the Model EC-25 Sprinkler in unobstructed and obstructed construction applications, the Model EC-25 Sprinkler demonstrated exceptional performance while protecting Group A Plastic Commodities, as shown in Table 4. Note that the 15-in obstruction test simulated standard coverage “distance from obstruc-tion” requirements, rather than extended coverage requirements. In essence, the Model EC-25 Sprinklers were positioned closer to the obstruction than allowed by extended coverage obstruction rules.

Sprinkler SpacingNFPA 13 sprinkler spacing rules for extended coverage extra hazard and storage sprinklers are cited in Table 8.8.2.1.2 in the 2010 and 2007 Editions and Chapter 8.8.2 in the 2002 Edition. New in the 2007 Edition, the 15 ft (4,6 m) maximum spacing of extended coverage sprinklers offers even greater flexibility in optimiz-ing the number of sprinklers in a bay, as well as the location of outlets on the branch lines, especially when used with welded or mechanical tee fittings. Even when the 15-ft (4,6 m) maximum spacing allowance does not save a branch line, the ability to space the Model EC-25 Sprinkler at 12 ft (3,7 m) along the branch lines results in typical 24-ft (7,3 m) branch line pipe lengths with 2 outlets. Standard coverage sprinklers hav-ing the 100 ft2 (9,3 m2) spacing maximum result in spacing along the branch lines at 8 ft-0 in or 8 ft-3 in (2,4 m or 2,5 m), requiring 3 outlets and the possibility of non-typical branch line pipe lengths. Table 5 summarizes the spacing allowance for extended coverage sprinklers in Extra Hazard and High-Piled Storage Occupancies in NFPA 13. This table shows maximum spacing based on coverage area regardless of obstruction:

•14-ft maximum spacing when coverage area exceeds 144 ft2 (13,4 m2) up to 196 ft2 (18,2 m2) coverage area, or

•15-ft maximum spacing when coverage areas are equal to or less than 144 ft2 (13,4 m2)

Unobstructed/ Obstructed196 ft2 (18,2 m2) 14 ft (4,3 m)

144 ft2 (13,4 m2) 15 ft (4,6 m)

Using the larger coverage area or the larger spacing provides a significant amount of flexibility, resulting in significant branch line savings when using the Model EC-25 Sprinkler as shown in Table 6.

The branch line saving includes not just the material, but a reduction in the labor required to hang the branch lines and install the sprinklers. As shown in Figure 1 with optimal bay sizing, you can save a branch line and take advantage of the full 196 ft2 (18,2 m2) coverage area.

In some bays where you cannot take advantage of the full 14-ft (4,2m) spacing with 196 ft2 (18,2 m2) coverage area, you can take advantage of the Model EC-25 Sprinkler’s flexibility to reduce a branch line at the lower 144 ft2 (13,4 m2) coverage area.

NFPA 13 Operating Pressures With the Model EC-25 Sprinkler, the myth that extended coverage sprinklers require too much pressure has been shattered. Keep in mind that this sprinkler has the flexibility of the S x L Spacing Rules for the purpose of hydraulic calculations (density/area method). NFPA 13 (2002 and later) states for determining the cover-age area of sprinklers listed for extended coverage extra hazard or high-piled storage “shall be permitted to be spaced in accordance with the requirements of 8.5.2 and 8.5.3”. Sections 8.5.2 and 8.5.3 allow the S x L Spacing Rules normally reserved for standard coverage sprinklers to determine the maximum area of coverage for these extended coverage sprinklers. Traditionally, extended coverage sprinklers such as residential squared off the maximum spacing dimension. For example, when calculating a 14 ft x 10 ft (4,3 m x 3,0 m) actual spacing for traditional extended coverage sprinklers, NFPA required squaring the maximum dimension of 14 ft (4,3 m), for a result of 196 sq ft2 (18,2 m2), rather than the actual 140 ft2 (13,0 m2). The allowance of S x L Spacing Rules for the extended coverage extra hazard or high-piled storage extended coverage sprin-klers allows the actual 140 ft2 (13,0 m2) to be used for the hydraulic calculation of the system. This allowance results in lower required sprinkler flows as compared to the “squared-off” method required for other extended coverage sprinklers for light hazard and ordinary hazard occupancies and residential sprinklers.

The 2010 Edition of NFPA 13 states the S x L Spacing Rules as follows: 8.5.2 Protection Areas per Sprinkler.

8.5.2.1 Determination of the Protection Area of Coverage.

8.5.2.1.1 The protection area of coverage per sprinkler (As) shall be determined as follows: (1) Along branch lines as follows:

(a) Determine distance between sprinklers (or to wall or obstruction in the case of the end sprinkler on the branch line), both upstream and downstream.

(b) Choose the larger of either twice the distance to the wall or the distance to the next sprinkler.

(c) This dimension will be defined as S.

(2) Between branch lines as follows:

(a) Determine perpendicular distance to the sprinkler on the adjacent branch line (or to a wall or obstruction in the case of the last branch line) on each side of the branch line on which the subject sprinkler is positioned.

(b) Choose the larger of either twice the distance to the wall or obstruction or the dis-tance to the next sprinkler.

(c) This dimension will be defined as L.

8.5.2.1.2 The protection area of coverage of the sprinkler shall be established by multiplying the S dimension by the L dimension, as follows: As = S x L

While the Model EC-25 Sprinkler, when used in accordance with NFPA 13 (2010), affords very low oper-ating pressures when spaced at 196 ft2 (18,2 m2) across a wide range of densities, even lower pressures can be realized by reducing the spacing to less than 196 ft2 (18,2 m2) but greater than the maximum of 100 ft2 (9,3 m2) allowed for standard coverage sprinklers. Refer to Table 7 for examples of required pressures at different spacings greater than 100 ft2 (9,3 m2).

FM Global Lowest Hydraulic DemandWhile ESFR Sprinklers have become the standard in ceiling-only storage protection over the last several years, the Model EC-25 Sprinkler now has the lowest system demand specified in FM Global Property Loss Prevention Data Sheet 8-9, July 2011 Revision, and Engineering Notice 06-11. The Model EC-25 Sprinkler only requires a 6-sprinkler design for ceilings of 30 ft (9,0 m) or less as compared to ESFR sprinklers that require a 12-sprinkler design. Reducing the sprinklers in the design by half translates into a significant saving in hydraulic demand for the system while almost doubling the sprinkler’s coverage area resulting in fewer branch lines and sprinklers.

The Model EC-25 Sprinkler requires an 8-sprinkler design for ceilings of 35 ft (10,5 m) compared to ESFR sprinklers, which require 12 sprinklers. This one-third reduction of sprinklers required in the design trans-lates into a significant saving in hydraulic demand for the system while requiring fewer branch lines and sprinklers.

The Model EC-25 Sprinkler provides similar savings for Class 1 to 4 and Cartoned Unexpanded Plastic Commodities in Solid-Piled, Palletized, Shelf, or Bin-Box storage arrangements.For storage buildings, the average ceiling height is the range of 27 to 34 ft (8.2 to 10.4 m). Therefore, for most buildings, the Model EC-25 Sprinkler provides a new level of performance that requires less water over a larger coverage area with fewer branch lines, fewer sprinklers, and often lower pressures than ESFR sprinklers in common use today.

SummaryIn summary, the TYCO Model EC-25 Storage Sprinkler provides lower installed cost and better fire protec-tion when compared to standard coverage sprinkler systems because of these key benefits:

•Better Fire Protection In fire tests that compared the Model EC-25 Extended Coverage Sprinkler with K-8.0 (115), K-11.2 (160), and K-16.8 (240) standard coverage sprinklers, the Model EC-25 Sprinkler opened fewer sprinklers and consumed fewer pallets.

•Fewer Branch Lines The Model EC-25 Sprinkler provides significant flexibility in optimizing the number of branch lines in a bay supporting distances from 8 ft to 14 ft (2,4 m x 4,3 m) with a coverage area up to 196 ft2 (18,2 m2). Spacing to the 15 ft (4,6 m) maximum is allowed with a maximum coverage area of 144 ft2 (13,4 m2).

•Fewer SprinklersThe same extended coverage that reduces the number of branch lines also reduces the number of sprin-klers on the branch lines.

•Lower Operating PressuresUsing the NPFA 13 S x L Spacing Rules, the Model EC-25 Sprinkler can cover smaller areas while oper-ating at lower pressures, delivering 0.67 GPM/ft (27,2 mm/min) at 100 ft2 (9,3 m2) spacing with an oper-ating pressure of only 7 psi (0.48 bar).

•Lowest Hydraulic System Demand The Model EC-25 Sprinkler provides a minimal water requirement, combined with extended coverage spacing, for ceiling heights of 35 ft (10,5 m) or less as provided in FM Global Property Loss Prevention Data Sheet 8-9, July 2011 Revision, and Engineering Bulletin 06-11.
