General

Description

The Model ESFR-17 Sprinklers (Ref.

Figure 1) are “Early Suppression

Fast Response Sprinklers” having a

nominal K-factor of 16.8. They are

suppression mode sprinklers, and

their use is especially advantageous

as a means of eliminating the use of

in-rack sprinklers, when protecting

high-piled storage.

The Model ESFR-17 is primarily de-

signed for use in ceiling only sprin-

kler systems (i.e. no in-rack sprin-

klers) for the protection of storage

heights of most encapsulated or non-

encapsulated common materials in-

cluding cartoned unexpanded plas-

tics of up to 35 ft. (10,7 m) and with

ceiling heights of up to 40 ft. (12,2

m), as well as cartoned expanded

plastics of up to 25 ft. (7,6 m) with

ceiling heights of up to 30 ft.(9,1 m).

In addition, the protection of some

storage arrangements of roll paper

and rubber tires can be considered

as well.

Also, in some cases, the Model

ESFR-17 can be used to protect stor-

age heights up to 40 ft. (12,2 m) with

ceiling heights up to 45 ft. (13,7 m)

in combination with one level of in-

rack sprinklers.

The ESFR-17 provides the system

designer with hydraulic options not

presently available to the traditional

ESFR sprinklers having a nominal

K-Factor of 14.0. In particular, the

Model ESFR-17 has been designed

to operate at substantially lower end

head pressures, as compared to

ESFR sprinklers having a nominal

K-Factor of 14.0. This feature offers

flexibility when sizing the system pip-

ing, as well as possibly reducing or

eliminating the need for a system fire

pump.

Operation. The fusible link assembly

is comprised of two link halves which

are joined together by a thin layer of

solder. When the rated temperature

is reached, the solder melts and the

two link halves separate, which then

allows the sprinkler to activate and

flow water.

WARNINGS

The Model ESFR-17 Sprinklers de-

scribed herein must be installed and

maintained in compliance with this

document, as well as with the appli-

cable standards of the National Fire

Protection Association, in addition to

the standards of any other authori-

ties having jurisdiction (e.g., FM

Global). Failure to do so may impair

the integrity of these devices.

The owner is responsible for main-

taining their fire protection system

and devices in proper operating con-

dition. The installing contractor or

sprinkler manufacturer should be

contacted relative to any questions.

Physical Characteristics

The Model ESFR-17 utilizes a dezin-

cification resistant bronze alloy

frame. The strut and hook are monel;

and, the button, deflector, and com-

pression screw are bronze. The

frame orifice is sealed with a gas-

keted spring plate (Belleville Seal)

consisting of a beryllium nickel disc

spring that is sealed on both its in-

side and outside edges with a Tef-

lon



gasket, and the two halves of

the fusible link assembly are nickel.

Design

Criteria

The Model ESFR-17 Sprinklers (SIN

TY7226) may be used to protect the

same types of storage and building

heights (up to 40 ft. (12,2 m) without

in-rack sprinklers, or 45 ft. (13,7 m)

with one level of in-rack sprinklers)

as 14.0 K-Factor ESFR sprinklers,

excluding storage of roll tissue,

flammable liquids, aerosols, and

exposed expanded plastics. Refer

to the appropriate FM Global Data

Sheet and Engineering Bulletin enti-

tled “Tyco Fire Products Model

TY7226, K16.8 Suppression-Model

Sprinklers” for details of appropriate

applications and design specifica-

tions.

A. Hydraulic Design: Design should

be 12 sprinklers, supplying four

sprinklers on three branch lines, at

the following pressures based on

equivalence to 14.0 K-Factor

ESFR sprinkler flows:

K=14.0 K=16.8

75 (5,2) 52 (3,6)

90 (6,2) 63 (4,3)

B. System Type: wet-pipe only (no

preaction or dry-pipe).

C. Sprinkler Spacing: The maximum

area of coverage is 100 ft2

(9,3m2) and the minimum area of

coverage is 80 ft2(7,4 m2).

The maximum distance between

sprinklers on branch lines or be-

tween branch lines is 12 ft. (3,7 m)

for buildings up to 30 ft. (9,1 m)

high, and 10 ft. (3,1 m) for build-

ings higher than 30 ft. (9,1 m) and

up to 45 ft. (13,7 m).

The minimum distance between

sprinklers on branch lines or be-

tween branch lines is 8 ft. (2,4 m).

C. Sprinkler Position: Position sprin-

klers so that the deflectors are lo-

cated at a maximum distance of

14 inches (360 mm) and a mini-

mum distance of 4 inches (100

mm) below the ceiling.

D. Hose Stream Demand and

Water Supply Duration:

250 GPM (950 LPM) and 60 min-

utes respectively.

F. Other Details: All other details are

the same as for pendent 14.0

K-Factor ESFR sprinklers as rec-

ommended in the following FM

Global Data Sheets:

2-2, “Installation Guidelines for

Early Suppression Fast Response

Sprinklers”

8-3, “Rubber Tire Storage”

8-9, “Storage of Commodities”

8-21, “Roll Paper Storage”

8-24, “Idle Pallet Storage”

G. Mixed Occupancies:

16.8 K-Factor ESFR sprinklers

may be used in adjacent non-stor-

age occupancies which qualify for

use with quick response sprinklers

as indicated in FM Global Data

Sheet 3-26, Table 2, using design

guidelines as described above.

Installation

The Model ESFR-17 Pendent Sprin-

klers are to be installed in accord-

ance with the following instructions:

NOTE

Damage to the fusible Link Assem-

bly during installation can be

avoided by handling the sprinkler by

the frame arms only (i.e., do not ap-

plypressuretothefusibleLinkAs-

sembly), and by using the appropri-

ate sprinkler wrench. Damaged

sprinklers must be replaced.

A leak tight 3/4 inch NPT sprinkler

joint should be obtained with a

torque of 10 to 20 ft.lbs. (13,4 to

26,8 Nm). Higher levels of torque

may distort the sprinkler inlet with

consequent leakage or impairment

of the sprinkler.

Step 1. The ESFR-17 Sprinkler must

be installed in the pendent position.

Step 2. With pipe thread sealant ap-

plied, hand tighten the sprinkler into

the sprinkler fitting. Do not apply

pressure to the Link Assembly, and

handle the ESFR-17 Sprinkler only

by the Frame arms.

Step 3. Wrench tighten the ESFR-17

Sprinkler using only the W-Type 21

Sprinkler Wrench (Ref. Figure 2) and

by fully engaging (seating) the

wrench with the sprinkler wrench

flats.

Step 4. After installation, inspect the

Link Assembly of each ESFR-17

Sprinkler for damage. In particular,

verify that the Link Assembly and

Hook are positioned as illustrated in

Figure 1, and that the Link Assembly

has not been bent, creased, or

forced out of its normal position in

any way.

Damaged sprinklers must be re-

placed.

Care &

Maintenance

The Model ESFR-17 must be main-

tained and serviced in accordance

with the following instructions:

NOTE

Before closing a fire protection sys-

tem main control valve for mainte-

nance work on the fire protection sys-

tem which it controls, permission to

shut down the affected fire protec-

tion systems must be obtained from

the proper authorities and all person-

nel who may be affected by this ac-

tion must be notified.

Sprinklers which are found to be

leaking or exhibiting visible signs of

corrosion must be replaced.

Automatic sprinklers must never be

shipped or stored where their tem-

perature will exceed 100°F/38°C and

they must never be painted, plated,

coated, or otherwise altered after

leaving the factory. Modified or over-

heated sprinklers must be replaced.

Care must be exercised to avoid

damage - before, during, and after

installation. Sprinklers damaged by

dropping, striking, wrench twist/slip-

page, or the like, must be replaced.

The owner is responsible for the in-

spection, testing, and maintenance

of their fire protection system and de-

vices in compliance with this docu-

ment, as well as with the applicable

standards of the National Fire Protec-

tion Association (e.g., NFPA 25), in

addition to the standards of any

other authorities having jurisdiction.

The installing contractor or sprinkler

manufacturer should be contacted

relative to any questions.

It is recommended that automatic

sprinkler systems be inspected,

tested, and maintained by a qualified

Inspection Service.
