Worldwide Contacts Model ESFR-17 16.8 K-factor Dry Type Pendent Sprinklers Early Suppression, Fast Response 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. 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 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 box-in-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. 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 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. Sprinkler Identification Number (SIN) See Table B for sprinkler identification number.
