(13.7 m) High: Locate the deflector between 6"and 14"(152 and 356 mm)below the ceiling. • The minimum area of coverage allowed per sprinkler is 64 ft'(5.8 m2)per NFPA 13. Maximum Roof or Ceiling Slope: 2 in 12(167 mm/m or 9.5 degrees). Sprinkler Position:Approved for use only in the pendent position.Align the deflector parallel with the ceiling or roof. System Type:Wet systems only. Deflector Distance from Walls:At least 4"(102 mm)from walls,and no more than one-half the allowable distance permitted between sprinklers. Clearance from Deflector to Top of Storage:At least 36"(914 mm). Maximum Distance Between Sprinklers:The maximum area of coverage allowed per sprinkler is 100 ft'(9.3 • For buildings over 30 ft(9.1 m)high,spacing between sprinklers and/or branch lines must be from 8 to 10 ft(2.4 to 3.1 m)**. • For building heights up to 30 ft(9.1 m), the spacing allowed between sprinklers and/or branch lines is 8 to 12 ft(2.4 to 3.7 m), provided the area covered per sprinkler does not exceed the maximum 100 ft2(9.3 m2)allowed**. **Refer to the Installation Standards for permissible deviations from the maximum sprinkler spacing rules above,to eliminate obstructions created by trusses and bar joists when using ESFR sprinklers. Note: If the ceiling is beam and girder or panel construction, locate sprinklers in the bays rather than under the beams. ESFR Cold Storage System Viking ESFR Sprinkler VK510 is also cULus Listed for use with a maximum 50%by volume factory premix propylene glycol and water antifreeze solu- tion.This Listing is based on full-scale fire testing at Underwriter's Laboratories.The following limitations of system design and application shall apply: Storage Arrangements: Solid-piled,or open rack(single, double, multiple, or portable), palletized storage(pallets limited to wood),with no open-top containers or solid shelves. Commodity Classification: Limited to Class II or less. Maximum Storage/Ceiling Heights and minimum pressure requirements: • Storage height up to 35 ft. (10.7 m) with ceiling height up to 40 ft. (12.2 m) with a minimum system design pressure of 40 PSI (2.76 Bar). OR: • Storage height up to 40 ft.(12.2 m)with ceiling height up to 45 ft-3 in.(13.8 m)with a minimum system design pressure of 60 PSI (4.14 Bar). Maximum System Volume of the Antifreeze Water Solution: Limited to 1,100 gallons(4 163 liters). Minimum Temperature: -21 OF(-29.4°C). Maximum Percentage by Volume of Propylene Glycol: 50% mixed with water for antifreeze solution. • Where the minimum temperature in the area being protected is 8 OF (-13.3 °C) or above, 35% percent by volume of propylene glycol factory premixed with water must be used.Viking requires Firefighter Eliminator C premix 35%propylene glycol/water mixture with a freeze temperature rating(freeze point)of 2.4 OF(-16.4°C). OR: • Where the minimum temperature in the area being protected is between 8 OF (-13.3 °C) and -21 OF (-29.4 °C), the percentage by volume of propylene glycol must be 50%, factory premixed with water for antifreeze solution. Viking requires Firefighter Eliminator F type 50% propylene glycol/water mixture,with a freeze temperature rating(freeze point)of-26 OF(-32.2°C). Refer to data page 45a-j"Viking ESFR Cold Storage System"in the Freezer Storage section of the Viking data book. IMPORTANT:Always refer to Bulletin Form No. F_091699-Care and Handling of Sprinklers.Viking ESFR Pendent Sprinklers are to be installed in accordance with the latest edition of Viking technical data, the latest standards of NFPA, VdS, LPCB, and any other Authorities Having Jurisdiction, and also with provisions of governmental codes, ordinances, and standards whenever applicable.
