General

Description

The Series TY-FRB, 5.6 K-factor Up-

right and Pendent Intermediate Level

Sprinklers described in this data sheet

are automatic sprinklers of the “quick

response” 3 mm frangible bulb type.

They are “standard spray” sprinklers

intended for use in ﬁre sprinkler sys-

tems designed in accordance with the

standard installation rules recognized

by the applicable Listing or Approval

agency (e.g., UL Listing is based on

NFPA requirements). Both the Up-

right and Pendent Sprinklers produce

a hemispherical water distribution pat-

tern below the deﬂector.

Intermediate Level Sprinklers are pri-

marily designed for use in rack stor-

age sprinkler systems where their

thermally sensitive elements must be

shielded from the water spray of high-

er elevation sprinklers that could op-

erate earlier during a ﬁre. Intermediate

Level Sprinklers are also used in oth-

er applications such as beneath open

gridded catwalks.

For additional Series TY-FRB Sprin-

kler information, see Technical Data

Sheet TFP172. For additional Guard

and Shield information, see Technical

Data Sheet TFP780.

NOTICE

The Series TY-FRB 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 authorities

having jurisdiction. Failure to do so

may impair the performance of these

devices.

The owner is responsible for maintain-

ing their ﬁre protection system and

devices in proper operating condi-

tion. The installing contractor or sprin-

kler manufacturer should be contact-

ed with any questions.

Operation

The glass bulb contains a ﬂuid which

expands when exposed to heat. When

the rated temperature is reached, the

ﬂuid expands sufﬁciently to shatter

the glass bulb, allowing the sprinkler

to activate and water to ﬂow.

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

to operate in a ﬁre situation or cause

it to operate prematurely.

The Series TY-FRB, 5.6 K-factor Upright and Pendent Intermediate Level Sprinklers are quick-response automatic sprinklers of the 3 mm frangible bulb type. These "standard spray" sprinklers are designed for use in fire sprinkler systems that comply with standard installation rules recognized by applicable Listing or Approval agencies, such as UL Listing based on NFPA requirements. Both the Upright and Pendent Sprinklers produce a hemispherical water distribution pattern below the deflector.

Intermediate Level Sprinklers are primarily intended for use in rack storage sprinkler systems where their thermally sensitive elements must be shielded from the water spray of higher elevation sprinklers that could operate earlier during a fire. They are also used in other applications, such as beneath open gridded catwalks.

Function Description

The glass bulb within the sprinkler contains a fluid that expands when exposed to heat. When the rated temperature is reached, the fluid expands sufficiently to shatter the glass bulb, allowing the sprinkler to activate and water to flow, providing fire suppression.

Usage Features

Installation: The sprinklers must be installed in compliance with this document, applicable National Fire Protection Association (NFPA) standards, and any other authorities having jurisdiction.
General Installation Instructions:
- Do not install if the bulb is cracked or if there is a loss of liquid from the bulb. A small air bubble (approximately 1/16 inch for 135°F to 3/32 inch for 286°F ratings) should be present when the sprinkler is held horizontally.
- A leak-tight 1/2 inch NPT sprinkler joint requires a torque of 7 to 14 ft.-lbs. (9.5 to 19.0 Nm). Higher torque levels can distort the sprinkler inlet and cause leakage or impairment.
Upright Sprinkler Installation (TY313 with G1/S1 Guard with Shield):
1. Apply pipe thread sealant and hand tighten the sprinkler into the fitting.
2. Tighten the sprinkler using only the W-Type 6 Sprinkler Wrench (applied to the wrench flats).
3. Mount the Model G1/S1 Guard with Shield on the sprinkler. Spread the two halves of the Guard enough to pass by the deflector.
4. Spread the two halves of the Sprinkler Base Plates enough to pass over the sprinkler Thread Relief portion.
5. Position the Sprinkler Guard on the Thread Relief portion, engage the Bars with Clips from opposing Guard Halves, then slide the Clips up until they are seated against the Base Plates. The Clips must seat against the Base Plates for proper installation. The Guard Installation Tool (shipped with guards) can assist, and pliers may be used. The G1/S1 Guard with Shield can be located in any position relative to the sprinkler frame arms.
Pendent Sprinkler Installation (TY323 with S2 Shield and G1 Guard):
1. Thread the S2 Shield onto the sprinkler threads with the stamped markings toward the deflector, just to the end of the threads.
2. Roll the O-Ring over the sprinkler threads until it seats against the Shield.
3. Apply pipe thread sealant and hand tighten the sprinkler into the fitting.
4. Tighten the sprinkler using only the W-Type 6 Sprinkler Wrench (applied to the wrench flats).
5. Rotate the S2 Shield clockwise (looking up) to slightly compress the O-Ring between the Shield and sprinkler fitting. (Installation is complete if only S2 Shield is used.)
6. If installing a G1 Guard, mount it on the sprinkler. Spread the two halves of the Sprinkler Guard enough to pass by the deflector.
7. Spread the two halves of the Sprinkler Base Plates enough to pass over the sprinkler Thread Relief portion.
8. Position the Sprinkler Guard on the Thread Relief portion, engage the Bars with Clips from opposing Guard Halves, then slide the Clips up until they are seated against the Base Plates. The Clips must seat against the Base Plates for proper installation. The Guard Installation Tool can assist, and pliers may be used. The G1 Guard can be located in any position relative to the sprinkler frame arms.

Maintenance Features

General Maintenance: Sprinklers must be maintained and serviced in accordance with this document and applicable NFPA 25 standards.
System Shutdown: Before closing a fire protection system main control valve for maintenance, permission must be obtained from proper authorities and all affected personnel must be notified.
Replacement:
- Sprinklers found 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. Modified sprinklers must be replaced.
- Sprinklers exposed to corrosive products of combustion, but not operated, should be replaced if they cannot be completely cleaned by wiping or brushing with a soft bristle brush.
- Sprinklers damaged by dropping, striking, wrench twist/slippage, or those with a cracked bulb or lost liquid from the bulb must be replaced.
Inspection and Testing: The owner is responsible for the inspection, testing, and maintenance of their fire protection system and devices in compliance with this document, NFPA 25, and any other authorities having jurisdiction. It is recommended that automatic sprinkler systems be inspected, tested, and maintained by a qualified Inspection Service.
