DESCRIPTION <br /> Viking fire sprinklers consist of a threaded frame with a specific waterway or orifice size and a deflector for distributing water in a <br /> specified pattern.A closed or sealed sprinkler refers to a complete assembly, including the thermosensitive operating element.An <br /> open sprinkler does not use an operating element and is open at all times.The distribution of water is intended to extinguish a fire <br /> or to control its spread. <br /> Viking sprinklers are available in several models and styles. Refer to specific sprinkler technical data pages for available styles, <br /> finishes, temperature ratings, thread sizes, and nominal K-Factors for the particular model selected. <br /> 2. LISTINGS AND APPROVALS <br /> Refer to the Approval Charts on the appropriate sprinkler technical data page(s) and/or WARNING:Cancer and Reproductive Harm- <br /> approval agency listings. www.P65Warnings.ca.gov <br /> 3. TECHNICAL DATA <br /> Pressure Ratings: <br /> Maximum allowable water working pressure is 175 psig (12 Bar) unless rated and specified for high water working pressure [250 <br /> psig (17.2 bar)]. <br /> Sprinkler Identification: <br /> Viking sprinklers are identified and marked with the word "Viking", the sprinkler identification number (SIN) consisting of"VK" plus <br /> a three digit number', the model letter, and the year of manufacture. <br /> Available Finishes: <br /> Viking sprinklers are available in several decorative finishes. Some models are available with corrosion-resistant coatings or are <br /> fabricated from non-corrosive material. Refer to the sprinkler technical data page for additional information. <br /> Available Temperature Ratings: <br /> Viking sprinklers are available in several temperature ratings that relate to a specific temperature classification.Applicable installa- <br /> tion rules mandate the use and limitations of each temperature classification. In selecting the appropriate temperature classifica- <br /> tion, the maximum expected ceiling temperature must be known. When there is doubt as to the maximum temperature at the <br /> sprinkler location, a maximum-reading thermometer should be used to determine the temperature under conditions that would <br /> show the highest readings to be expected. In addition, recognized installation rules may require a higher temperature classifica- <br /> tion,depending upon sprinkler location,occupancy classification,commodity classification,storage height,and other hazards. In <br /> all cases,the maximum expected ceiling temperature dictates the lowest allowable temperature classification.Sprinklers located <br /> immediately adjacent to a heat source may require a higher temperature rating. <br /> K-Factors: <br /> Viking sprinklers are available in several orifice sizes with related K-Factors. The orifice is a tapered waterway and, therefore, the <br /> K-Factor given is nominal. Nominal U.S. K-Factors are provided in accordance with the 1999 edition of NFPA 13, Section 3-2.3. <br /> Refer to the specific data page for appropriate K-Factor information. <br /> Available Styles: <br /> Viking sprinklers are available for installation in several positions as indicated by a stamping on the deflector. The deflector style <br /> dictates the appropriate installation position of the sprinkler; it breaks the solid stream of water issuing from the sprinkler orifice to <br /> form a specific spray pattern.The following list indicates the various styles and identification of Viking sprinklers. <br /> UPRIGHT SPRINKLER:A sprinkler intended to be installed with the deflector above the frame so water flows upward through the <br /> orifice, striking the deflector and forming an umbrella-shaped spray pat- <br /> tern downward.

The deflector provides a spherical type pattern with 40 to 60 percent of the water initially directed downward and a <br /> proportion directed upward. Must be installed in accordance with installation rules for conventional or old style sprinklers. DO <br /> NOT USE AS A REPLACEMENT FOR STANDARD SPRAY SPRINKLERS.
