Tyco Fire Product EC-17 Manuel utilisateur

General

Description

The Tyco®Model EC-17 Extended

Coverage Pendent Sprinklers (Ref.

Figure 1) are “Control-Mode Extended

Coverage Sprinklers” having a nomi-

nal K-factor of 16.8. Their use is espe-

cially advantageous as a means of de-

creasing the number of required

sprinklers to protect occupancies re-

quiring an area/density application of

water.

Features:

•The EC-17 Sprinklers offer a maxi-

mum coverage area of 196 ft2(18,2

m2) at a maximum spacing of 14 feet

(4,3 m), almost double that of stand-

ard coverage sprinklers used for

similar applications.

•The EC-17 Sprinklers offer a maxi-

mum coverage area of 144 ft2(13,4

m2) at a maximum spacing of 15 ft.

(4,3 m) which can be beneficial to

maximizing sprinkler line spacing.

•The 144 ft2(13,4 m2) coverage with

maximum spacing of 15 ft. (4,3 m)

for the EC-17 Sprinklers can be

beneficial for retrofitting an existing

system to a higher applied water

density, especially where the sys-

tem had utilized sprinklers having a

maximum sprinkler spacing of 15

feet (4,3 m).

TherecessedversionoftheModelEC-

17 Pendent Sprinkler is intended for

use in areas with a finished ceiling. It

uses a two-piece Style 30 (3/4 inch

NPT) Recessed Escutcheon with 1/4

inch (6,4 mm) of recessed adjustment,

or up to 1/2 inch (12,7 mm) of total

adjustment from the flush pendent po-

sition. The adjustment provided by the

RecessedEscutcheonreducestheac-

curacy to which the fixed pipe drops to

the sprinklers must be cut.

Applications for the Model EC-17

Sprinklers are expanding beyond the

current testing. For information re-

garding additional research fire tests

that may be acceptable to an Authority

Having Jurisdiction please contact the

Technical Services Department.

WARNINGS

The Model EC-17 Sprinklers de-

scribed herein must be installed and

maintained in compliance with this

document, as well as with the applica-

ble standards of the National Fire Pro-

tection Association, in addition to the

standards ofany other authorities hav-

ing jurisdiction. Failure to do so may

impair the performance of these de-

vices.

The owner is responsible for maintain-

ing their fire protection system and de-

vices in proper operating condition.

The installing contractor or sprinkler

manufacturer should be contacted

with any questions.

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 in-

stallation can permanently damage

a sprinkler system or its compo-

nents and cause the sprinkler to fail

tooperate in a firesituationorcause

it to operate prematurely.

Operation

The fusible link assemblyis comprised

of two link halves that are joined to-

gether 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.

Design

Criteria

The Tyco®Model EC-17 Extended

Coverage Pendent Sprinklers (SIN

TY7228) are UL and C-UL Listed,

with

the exception of using plastic pallets

as described in 5.6.2.6 of NFPA 13-

2007

, for installation in accordance

with the extended coverage pendent

spray sprinkler requirements of NFPA

13, or other applicable NFPA stand-

ards, when used in conjunction with

the following guidelines :

•Suitable for the protection of extra

hazard and high-piled storage occu-

pancies where area/density design

criterion are provided.

•Suitable for “unobstructed” or “non-

combustible obstructed” construc-

tion.

•The Model EC-17 Sprinklers, having

been specifically tested and listed

for noncombustible obstructed con-

struction, are suitable for use within

trusses or bar joists having non-

combustible web members greater

than1inch(25,4mm) whenapplying

the four times obstruction criteria

rule defined under “Obstructions to

Sprinkler Discharge Pattern Devel-

opment”.

•The maximum area of coverage per

sprinkler is 196 sq. ft. (18,2 m2).

•The maximum distance between

sprinklersis 15feet(4,6m) whenthe

coverage does not exceed 144 ft.2

(13,4 m2), and the maximum dis-

tance between sprinklers is 14 feet

(4,3 m) when the coverage does not

exceed 196 ft2(18,2 m2).

•The minimum distance between

sprinklers is 8 feet (2,44 m).

•The minimum flow requirement is to

be based on the design density ap-

plied over the actual area of cover-

age per sprinkler.

For example: when sprinkler spac-

ing is 14 feet by 12 feet - 6 inches

(4,3 x3,8 m) or 175ft2(16,3m2), and

the design density is 0.3 gpm/ft2

(16,3 mm/m), the sprinkler design

flow rate is 53 GPM (200 LPM) and

the required design pressure is 10

psi (0,7 bar).

•The minimum clearance between

the deflector and the top of storage

is 36 inches (0,9 m).

•The ordinary and intermediate tem-

perature rated EC-17 Sprinklers

have been investigated for use in

high-piled storage occupancies at

the hydraulic demand normally as-

sociated with high temperature

sprinklers.As such,theEC-17sprin-

klers are listed storage sprinklers

having a K-factor greater than 11.2

and having ordinary and intermedi-

ate temperature ratings (i.e., 160F

and 212F). Consequently, the EC-

17 Sprinklers, in accordance with

the NFPA 13, may be used in con-

junction with the density curves for

high temperature sprinklers.

Installation

NOTES

Damage to the fusible Link Assembly

during installation can be avoided by

handling the sprinkler by the frame

arms only and by usingthe appropriate

sprinkler wrench. Do not grip or apply

any force to the Fusible Link Assem-

bly. Damaged sprinklers must be re-

placed immediately.

A leak tight 3/4 inch NPTsprinkler 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 sprin-

kler inlet with consequent leakage or

impairment of the sprinkler.

The Model EC-17 Pendent Sprin-

klers must be installed in accordance

with the following instructions:

Step 1. The EC-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 any

forceto theLinkAssembly,and handle

the EC-17 Sprinkler only by the Frame

arms.

Step 3. Wrench tighten the EC-17

Sprinkler using only the W-Type 3

Sprinkler Wrench (Ref. Figure 3) and

by fully engaging (seating) the wrench

on the sprinkler wrench flats.

TheModel EC-17 Recessed Pendent

Sprinklers must be installed in ac-

cordance with the following instruc-

tions.

Step A. After installing the Style 30

Mounting Plate over the sprinkler

threads, and with pipe thread sealant

applied to the pipe threads, hand

tighten the sprinkler into the sprinkler

fitting.

Step B. Wrench tighten the EC-17

Sprinkler using only the W-Type 24

Sprinkler Wrench (Ref. Figure 4) and

fully engaging (seating) the wrench on

the sprinkler wrench flats.

Step C. After the ceiling has been in-

stalled, slide the Style 30 Closure over

the Model EC-17 Sprinkler and push

the Closure over the Mounting Plate

until its flange comes in contact with

the ceiling.

Care and

Maintenance

The Tyco®Model EC-17 must be

maintained and serviced in accord-

ance with the following instructions:

NOTE

Before closing a fire protection system

main control valve for maintenance

work on the fire protection system that

itcontrols,permissiontoshutdownthe

affected fire protection systems must

be obtained from the proper authori-

ties and all personnel who may be

affectedbythisactionmustbenotified.

Sprinklers that are found to be leaking

or exhibiting visible signs of corrosion

must be replaced.

Automatic sprinklers must never be

painted, plated, coated, or otherwise

altered after leaving the factory. Modi-

fied or over-heated sprinklers must be

replaced.

Care must be exercised to avoid dam-

age - before, during, and after instal-

lation. Sprinklers damaged by drop-

ping, striking, wrench twist/slippage,

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 in-

stalling contractor or sprinkler manu-

facturer should be contacted relative

to any questions.

Automaticsprinklersystemsshouldbe

inspected, tested, and maintained by a

qualified Inspection Service in accord-

ance with local requirements and/or

national code.
