Description

The Central Model ESLO Very Extra

Large Orifice Recessed Pendent and

Pendent Automatic Glass Bulb Sprinklers

are specifically designed for Extended

Coverage/Light Hazard for all Groups as

defined by NFPA 13. They are Listed as

Quick Response, up to 18'x18' spacing,

and as Standard Response, above 18'x18'

spacing. Maximum ceiling slope of 2" per

foot. The ESLO is Listed for smooth flat

horizontal ceilings as are all Extended

Coverage Light Hazard Sprinklers.

The ESLO provides the maximum in

design flexibility as it has a minimum

separation of only 9'-0" and is Listed for

flows and pressures associated with

16'x16', 18'x18' and 20'x20' spacing.

They are intended for use, as all ex-

tended coverage sprinklers are, with

hydraulically designed systems and using

the flows and pressures as shown in this

brochure. For the purpose of determining

the correct flow and pressure to use in the

hydraulic calculations, all spacing is

rounded up to the next higher category.

For example, 17'-6"x15'-0" spacing would

be calculated at the Listed 18'x18' flow and

pressure.

The advantage of the ESLO is the ability

to cover large areas, up to 400 square

feet, with pressures that compare to 1⁄2"

standard sprinklers spaced at their

maximum of 225 square feet. For ex-

ample, the ESLO can cover 20'x20'

spacing or 400 square feet with less

pressure than is required with 1⁄2" sprin-

klers at 225 square feet. (7.6 vs. 16.1)

The Model ESLO Sprinkler incorporates

a specially designed deflector that pro-

vides a much greater area of coverage

than standard commercial sprinklers.

The two (2) piece recessed escutcheon

assembly provides for 3⁄4" of field adjust-

ment.

Care &

Maintenance

Sprinklers must be handled care-

fully. They must not be transported

or stored where ambient temperature

may exceed 100°F/38°C. For best

results, store them in a dry, cool

location in the original shipping

package.

Do not install sprinklers that have

been dropped or visibly damaged.

Sprinklers must never be painted,

coated, plated, or altered in any other

way from manufactured condition or

they may not function properly. Any

sprinklers altered in such manner

must be replaced.

The owner is responsible for the

proper operating condition of all fire

protection devices and accessories.

The NFPA standard 25 entitled,

“Inspection, Testing and Maintenance

of Water-Based Fire Protection

Systems”

, contains guidelines and

minimum maintenance requirements.

Furthermore, the local

Authority

Having Jurisdiction

may have addi-

tional regulations and requirements

for maintenance, testing, and inspec-

tion that must be obeyed.

It is advisable to have sprinkler

systems inspected regularly by a

qualified inspection service. Length of

time between such inspections can

vary due to accessibility, ambient

atmosphere, water supply, and site

activity.

Do not attempt to reassemble or

otherwise reuse a sprinkler that has

operated. Replace any sprinkler

exhibiting corrosion or damage;

always use new sprinklers of the

same type and temperature rating as

replacements.

Because the discharge pattern is

critical to protection of life and

property, nothing should be hung or

attached to the sprinkler unit that

would disrupt the pattern. Such

obstructions must be removed. In the

event that construction has altered

the original configuration, the system

must be investigated and the protec-

tion level maintained.

Installation

The Model ESLO incorporates the

latest in heat-responsive glass bulb

technology. The operating mecha-

nism consists of a 3 mm liquid-filled

frangible capsule that is only 2.0 cm

in length.

Operation: The glass bulb capsule

operating mechanism contains a

heat-sensitive liquid that expands

upon application of heat. At the rated

temperature, the frangible capsule

ruptures, thereby releasing the orifice

seal. The sprinkler then discharges

water in a pre-designed spray pattern

to control the fire.

All Central Model ESLO Recessed

Pendent and Pendent Automatic

Sprinklers must be installed accord-

ing to the current NFPA 13 Standard

and these installation instructions.

Deviations from these requirements

and standards or any alteration to the

sprinkler itself will void any warranty

made by Central Sprinkler Company.

In addition, installation must also

meet local government provisions,

codes, and standards as applicable.

The system piping must be properly

sized to ensure the minimum required

flow rate at the sprinkler. Check for

the proper model, style, orifice size,

and temperature rating prior to

installation. Install sprinklers after the

piping is in place to avoid mechanical

damage; replace any damaged units.

Wet pipe systems must be

protected from freezing.

Upon completion of the installation,

the system must be tested per

recognized standards.

In the event of a thread leak,

remove the unit, apply new pipe joint

compound or tape, and reinstall.

Installation Sequence

Step 1. For Pendent and Recessed

Pendent sprinklers, the face of the

sprinkler fitting should be installed a

nominal 3⁄4" (±3⁄8") behind the ceiling

line. Adjustments are made via the

push-on escutcheon.

Step 2. Use only a non-hardening

pipe joint compound or Teflon* tape.

Apply only to the male threads.

Step 3. Hand tighten the sprinkler

into the fitting. Use a Central

Sprinkler Wrench, to tighten the unit

into the fitting. A leak-tight joint

requires only 7 to 14 ft.-lbs. of torque;

a tangential force of 14 to 28 lbs.

delivered through a 6" handle will

deliver adequate torque. Torque

levels over 21 ft.-lbs. may distort the

orifice seal, resulting in leakage.

* Listed as Quick Response.

** Listed as Standard Response Only.

≠

Recessed Pendent Sprinkler is Listed as Standard Response Only.

Caution: Minimum spacing between pendent and recessed

pendent sprinklers is 9'-0".

Ordering

Information

Do not attempt to replace sprinklers

without first removing the fire protec-

tion system from service. Be certain

to secure permission from all authori-

ties having jurisdiction, and notify all

personnel who may be affected

during system shutdown. A fire

watch during maintenance periods is

a wise precaution.

To remove the system from service

mode, first refer to the system

operating guide and valve instruction.

Drain water and relieve pressure in

the pipes. Remove the existing unit

and install the replacement, using

only the special sprinkler wrench. Be

certain to match model, style, orifice,

and temperature rating.

A fire protection system that has

been shut off after an activation

should be returned to service immedi-

ately. Inspect the entire system for

damage and replace or repair as

necessary. Sprinklers that did not

operate but were subjected to corro-

sive elements of combustion or

excessive temperatures should be

inspected, and replaced if need be.

The

Authority Having Jurisdiction

will

detail minimum replacement require-

ments and regulations.

Guarantee: Central Sprinkler Com-

pany will repair and/or replace any

products found to be defective in

material or workmanship within a

period of one year from the date of

shipment. Please refer to the current

Price List for further details of the

warranty.
