The model VK506 is a cULus Listed and FM Approved, Early Suppression Fast Response (ESFR) type storage sprinkler capable of suppressing specific high-challenge fires. ESFR sprinklers can eliminate the use of in-rack sprinklers when protecting high-piled storage of certain specified materials up to: UL: 40 ft. (12,2 m) with ceilings up to 45 ft. (13,7 m)* FM: 45 ft. (13,7 m) with ceilings up to 50 ft. (15,2 m)* They can also reduce or eliminate the need for a system fire pump and provide flexibility when sizing system piping. Viking VK506 ESFR Pendent Sprinklers are primarily intended to protect the following types of storage, which tend to produce severe-challenge fires: palletized and solid pile storage and single, double, multiple row, and portable open rack storage (no open-top containers or solid shelves). * Refer Technical Data, Approval Charts and Commodity Selection and Design Criteria Overview for cULus Listing and FM Approval requirements that must be followed.
Select Viking sprinklers are compatible with revolutionary InstaSeal® technology through the addition of new Torque-Assist caps. Make sure to look for the compatibility icon to ensure the correct sprinklers are being ordered for a job requiring InstaSeal technology.
