Sprinkler Identification Number database
Effective Jan. 21, 2001 all currently Listed fire sprinklers in the categories of automatic and open (VNIV), residential automatic (VKKW) and early suppression-fast response (ESFR) (VNWH), produced after this date, are required to be marked with a sprinkler identification number (SIN). The SIN will provide a means to identify the Listee and determine information about the sprinkler such as sprinkler type, K-factor, response type, and the category where the sprinkler is Listed.
The SINs for all three categories: automatic and open sprinklers, residential and ESFR are now located in a new category "Guide Information for (VNWA), Sprinkler Identification Number (SIN)." The VNWA category is a list of all SINs and their associated basic information. Additional information can be obtained by cross-referencing the SIN to the individual sprinkler Listings. While this list will not apply to products in the field manufactured prior to the adoption of this program, it will address present and future Listed sprinklers.
This category was established and the list was developed to assist authorities having jurisdiction, fire marshals, fire inspectors and pipe fitters/sprinkler installers in identifying the proper sprinkler when installing and maintaining sprinkler systems in accordance with NFPA 13 and NFPA 25.
