16.8 K-factor Dry Type Pendent Sprinklers

Early Suppression, Fast Response

General

Description

TYCO Model ESFR-17 Dry Type

Pendent Sprinklers are Early Suppression, Fast Response (ESFR) sprinklers having a nominal K-factor of 16.8.

They are suppression mode sprinklers that are especially advantageous as a means of eliminating in-rack sprinklers when protecting high-piled box-in-box refrigerated storage areas.

The Model ESFR-17 Dry Type Pendent

Sprinkler is FM Approved and has successfully undergone full-scale fire testing at FM Global, when used in conformance with applicable FM Global

Property Loss Prevention Data Sheets.

The Model ESFR-17 Dry Type Sprinkler consists of an ESFR sprinkler permanently secured to a sprinkler drop featuring an inlet with both grooved and threaded connections. The drop between the inlet and sprinkler remains dry until the sprinkler operates, allowing for a pendent sprinkler installation on a wet pipe sprinkler system where the dry drop and sprinkler are located in an area subjected to freezing temperatures.

The Model ESFR-17 Dry Type Sprinklers are primarily used for ceiling only sprinkler protection (i.e., no need for in-rack sprinklers) and used to protect solid piled, palletized, and rack storage that is subject to freezing temperatures.

The water supply is provided from a

IMPORTANT

Refer to Technical Data Sheet

TFP2300 for warnings pertaining to regulatory and health information.

Always refer to Technical Data

Sheet TFP700 for the “INSTALLER

WARNING” that provides cautions with respect to handling and installation of sprinkler systems and components. Improper handling and installation can permanently damage a sprinkler system or its components and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely.

Page 1 of 8 wet pipe system located outside of the refrigerated storage area. The Model

ESFR-17 Dry Type Sprinklers feature all of the same design criteria as 16.8

K-factor ESFR Pendent Sprinklers, and substantially lowers the end head pressure requirement as compared to the

14.0 K-factor ESFR Dry Type Pendent

Sprinklers.

Combining a 16.8 K-factor with a dry-type sprinkler design, the Model

ESFR-17 Dry Type Sprinkler provides the system designer with features that offer flexibility when sizing system piping, as well as possibly reducing or eliminating the need for a system fire pump when protecting high-piled boxin-box refrigerated storage areas.

The ESFR-17 Dry Type Sprinkler also includes two Insulating Seal Assemblies that help seal the clearance space around the sprinkler casing. The seal assemblies are intended to slow the exchange of air between the heated area and the protected area to help prevent humidity and temperature differential in the area around the sprinkler. Condensation on the sprinkler and subsequent ice buildup on or around the sprinkler can occur that might damage the sprinkler or prevent proper operation in a fire situation.

To install the Insulating Seal Assemblies, follow the installation instructions in this data sheet. The Insulating

Seal Assemblies are recommended to be installed on smooth, flat, and clean surfaces. If it is expected that environmental conditions may result in excessive condensation, additional sealing of the assembly is recommended.

There are specific situations, such as corrugated surfaces where alternate methods to seal the clearance hole are recommended. For additional guidance, contact Johnson Controls Technical Services.

NOTICE

The Model ESFR-17 Dry Type Pendent

Sprinklers described herein must be installed and maintained in compliance with this document, as well as with the applicable standards of the National

AUGUST 2018

Fire Protection Association (NFPA), in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices.

The owner is responsible for maintaining their fire protection system and devices in proper operating condition. Contact the installing contractor or product manufacturer with any questions.

Operation

The casing between the inlet and the sprinkler remains dry until the sprinkler operates. The fusible link assembly is comprised of two link halves that are joined together by a thin layer of solder.

When the rated temperature is reached, the solder melts and the two link halves separate, activating the sprinkler and allowing water to flow through the casing and to the activated sprinkler.

Do not attempt to add additional insulation around the barrel in the heated area as a method to minimize condensation. This will reduce the calculated exposure length.

Clearance Space

In accordance with NFPA 13, when protecting insulated freezer structures with dry type sprinklers, the clearance hole around the sprinkler barrel of the Dry Type Sprinkler and the clearance hole must be sealed. Sealing is accomplished by use of the Insulating

Seal Assemblies (Ref. Figure 7). Failure to use the Insulating Seal Assemblies will increase the potential for the formation of condensation on the sprinkler and subsequent ice build-up on or around the sprinkler can occur that might damage the dry type sprinkler and/or prevent proper operation in a fire situation.

FM Global 2-0

Consult FM Global and/or FM Global guidelines for allowable vertical distance from ceiling to centerline of thermal sensing element.

Installation

TYCO Model ESFR-17 Early Suppression, Fast Response 16.8K Pendent

Sprinklers must be installed in accordance with this section.

General Instructions

Avoid damage to the fusible Link

Assembly during installation by using only the Casing to handle the sprinkler and by using the appropriate sprinkler wrench. Do not apply pressure to the fusible Link Assembly. Failure to do so can lead to an unstable link assembly and premature activation of the sprinkler. Damaged sprinklers must be replaced.

Model ESFR-17 Dry Type Sprinklers must only be installed in fittings/connections that meet the requirements of the Design Criteria section. Refer to the Design Criteria section for other important requirements regarding piping design, exposure length, and the sealing of the clearance space around the sprinkler casing.

If a sprinkler using a threaded connection (vs. grooved connection) requires replacement, remove the sprinkler using only the W-Type 26 Sprinkler

Wrench. Fully engage the wrench on the inlet wrench hex (Ref. Figure 5).

Replace with the new sprinkler following the installation instructions in this section.

Threaded Connection

Instructions

A leak-tight 1-1/4 in. NPT sprinkler joint should be obtained by applying a minimum-to-maximum torque of 45 to

65 lb-ft (61 to 88 N ∙ m). Higher levels of torque can distort the sprinkler inlet with consequent leakage or impairment of the sprinkler.

Note: Install the Model ESFR-17 Dry

Type Pendent Sprinkler in the pendent position (Ref. Figure 5) by carefully raising the pendent sprinkler through the clearance hole. The deflector of the pendent sprinkler is to be parallel to the ceiling.

Step 1.

Apply a non-hardening pipe thread sealant such as TEFLON to the male 1-1/4 in. NPT inlet threads.

Step 2.

Wrench-tighten the Model

ESFR-17 Dry Type Sprinkler using only the W-Type 26 Sprinkler Wrench and by fully engaging the wrench on the inlet wrench hex (Ref. Figure 5). For reference, the “FRAME ARMS” marking can be used to align the frame arms with the System Pipe as shown in Figure 6.

Step 3.

After installation, inspect the

Link Assembly of each Model ESFR-17

Dry Type Sprinkler for damage. In particular, verify that the Link Assembly and Hook are positioned as illustrated in Figure 1, and that the Link Assembly is not bent, creased, or forced out of normal position in any way. Replace damaged sprinklers.

Step 4.

Install the insulation rings of the

Insulating Seal Assemblies by slipping the insulation rings around the sprinkler casing as shown in Figure 7. Place the inserts over the insulation rings by sliding the inserts around the casing.

Place the housings over the Inserts and insulation rings ensuring that the slot on the housings are 180 degrees to the inserts slot. Ensure that the Insulating Seal Assemblies are snug against the refrigerated storage ceiling. Secure the Insulating Seal Assemblies to the ceiling using two self-tapping screws per assembly.

Grooved Connection

Instructions

The following instructions are based on using the 2 in. Figure 705 Grooved

Flexible Coupling or the 2 inch Figure

577 Grooved Rigid Coupling.

Step 1.

Inspect the exterior groove and the end connection of the mating grooved connection and sprinkler to verify all burrs, loose debris, dirt, chips, paint and other foreign materials such as grease are removed. Sealing surfaces must be free from sharp edges, projections, indentations, and/or other defects.

Step 2.

Verify that the coupling and gasket grade are correct for the application intended. Refer to Technical

Data Sheet TFP1895 for additional gasket information. The sealing edges and the outer surfaces of the gasket should be covered with a fine layer of lubricant. To prevent deterioration of the gasket material, a silicone lubricant should be used to prevent freezing of the lubricant.

Step 3.

Install the Model ESFR-17 Dry

Type Pendent Sprinkler in the pendent position (Ref. Figures 4 and 7) by carefully raising the pendent sprinkler through the clearance hole. The deflector of the pendent sprinkler is to be parallel to the ceiling. Also, ensure that the

“FRAME ARMS” markings on the sprinkler casing are aligned with the System

Pipe (Ref. Figure 6).

Step 4.

Install the gasket by placing it over the sealing portion of the grooved inlet connection so that the gasket lip does not extend beyond the end of the groove sealing surface. Bring end of the grooved inlet together with end of grooved fitting ensuring vertical and horizontal alignment. Slide the gasket over both sealing surfaces.

Step 5.

With one bolt and nut removed, separate the coupling housings and place over the gasket. Verify that the coupling housings are over the gasket and that the coupling housing keys are fully engaged into the grooves.

Step 6.

Insert the bolt and nut into the coupling and finger tighten both nuts.

Verify that the bolt heads are fully recessed in the housing.

The 2 in. Figure 705 Grooved Flexible

Coupling Housing bolt pads must be in metal-to-metal contact. For Flexible

Coupling deflection data, refer to Technical Data Sheet TFP1820.

The 2 in. Figure 577 Grooved Rigid

Coupling has an intended gap of up to

1/16 of an inch at each pad to allow for positive rigid gripping onto the pipe. The patented tongue and groove design provides protection to the back of the gasket during installation.

Step 7.

Alternate between both sides of the coupling when tightening the bolts.

Torque bolts to 30 lb-ft (41 N ∙ m).

Step 8.

Install the insulation rings of the

Insulating Seal Assemblies by slipping the insulation rings around the sprinkler casing as shown in Figure 7. Place the inserts over the insulation rings by sliding the inserts around the casing.

Place the housings over the Inserts and insulation rings ensuring that the slot on the housings is 180 degrees to the inserts slot. Ensure that the Insulating Seal Assemblies are snug against the refrigerated storage ceiling. Secure the Insulating Seal Assemblies to the ceiling using two self-tapping screws per assembly.

Care and

Maintenance

TYCO Model ESFR-17 Early Suppression, Fast Response 16.8K Pendent

Sprinklers must be maintained and serviced in accordance with this section.

Before closing a fire protection system main control valve for maintenance work on the fire protection system that it controls, obtain permission to shut down the affected fire protection from the proper authorities and notify all personnel who may be affected by this action.

Sprinklers which 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. Modified or overheated sprinklers must be replaced.

A Vent Hole is provided in the Link

Assembly Button (Ref. Figure 1) to indicate if the Dry Sprinkler is remaining dry. Evidence of leakage from the Vent

Hole indicates potential leakage past the Inlet seal and the need to remove the sprinkler to determine the cause of leakage; such as an improper installation or an ice plug. Close the fire protection system control valve and drain the system before removing the sprinkler.

When replacing a sprinkler, remove and discard the old Insulating Seal Assemblies and replace as shown in Figure 7.

Care must be exercised to avoid damage to the sprinklers before, during, and after installation. Sprinklers damaged by dropping, striking, wrench twist/slippage, or the like, must be replaced.

The owner is responsible for the inspection, testing, and maintenance of their fire protection system and devices in compliance with this document, as well as with the applicable standards of the National Fire Protection Association, such as NFPA 25, in addition to the standards of any authorities having jurisdiction. Contact the installing contractor or product manufacturer with any questions.

Automatic sprinkler systems are recommended to be inspected, tested, and maintained by a qualified Inspection Service in accordance with local requirements and/or national codes.
