1. DESCRIPTION
Viking Standard Response Control Mode Specific Application (CMSA) Pendent
Sprinkler VK592 is a thermosensitive fusible element type spray sprinkler. With a
19.6 nominal K-Factor, the sprinkler provides greater flows at lower pressures than
sprinklers with smaller K-Factors. This feature allows reduced pipe sizing for hydrauli-
cally calculated sprinkler systems, and provides the higher densities required to allow
an increase in the hazard classification of an occupancy. Viking Standard Response
Sprinkler VK592 was subjected to full-scale high piled storage fire testing and is UL
Listed, FM Approved, and VdS Approved for use in protecting high-piled storage.
Viking Sprinkler VK592 is intended to protect Class I-IV commodities and plastic and
rubber commodities (cartoned, unexpanded only) stored palletized, solid piled, bin
boxes, shelf storage, and single, double, multiple row, and portable open rack storage
(no open-top containers or solid shelves). Sprinkler VK592 may also be used to protect
on-floor storage of idle wood pallets. Refer to Approval Chart 1 and Design Criteria
on pages 3-4 for UL Listing requirements, and refer to Approval Chart 2 and Design
Criteria on page 8 for FM Approval requirements that must be followed.
NOTE: Sprinkler VK592 is NOT approved for protecting expanded plastics, exposed
unexpanded plastics, rolled paper, baled cotton, aerosols, or rubber tires.
2. LISTINGS AND APPROVALS

Order Standard Response Control Mode Specific Application Pendent Sprinkler VK592 by adding the appropriate suffix for the
sprinkler temperature rating to the sprinkler base part number.
Finish Suffix: Brass = A
Temperature Suffix: 160 °F (71 °C) = C, 205 °F (96 °C) = E
For example, sprinkler VK592 with a Brass finish, with 1" NPT threads, and a 160 °F (71 °C) temperature rating = Part No. 14243AC.
Available Finishes And Temperature Ratings: Refer to Table 1.
