Reliable Model WP Series Window Protection Sprinklers are fast response, pendent vertical sidewall, specific application sprinklers designed to provide complete coverage and wetting of heat strengthened, tempered, or ceramic glass windows.
These sprinklers were tested and listed by Underwriters Laboratories for their ability to maintain the integrity of a window assembly placed in a test furnace for a 2-hour period. The test is based upon gas flow into the furnace as required to achieve a temperature in the furnace in the absence of sprinklers matching the standard time-temperature curve in ASTM E119.
Where approved in accordance with Sections 104 of the International Building Code and International Fire Code, which in part authorizes the use of alternative materials and methods, Model WP Series Window Sprinklers may be used as interior protection of non-operable windows or glazing that are part of a fire resistance rated wall in sprinklered or non-sprinklered buildings. With the thermal operating elements removed, some of these sprinklers may also be used for outdoor exposure protection of non-operable windows or glazing when installed on a deluge system in accordance with NFPA requirements.
Model WP Series Window Protection Sprinklers are available in a variety of finishes (see Table F). Model WP56 sprinklers in white polyester, black polyester, or Electroless Nickel PTFE (ENT) finishes are cULus Listed as corrosion resistant sprinklers. The Model WP56SS (Stainless Steel) is cULus listed as corrosion resistant without any additional finish, but may be polyester coated for aesthetic reasons. In addition to the exposed versions of the product, the Model WP56C offers a flat plate concealed option.
