Description

The Viking Standard Response High Challenge® Upright CMSA Sprinkler VK540 is a thermosensitive, glass-bulb sprinkler intended for use in protecting high piled storage occupancies in accordance with NFPA 13 rules for CMSA Sprinklers and FM Global criteria for storage sprinklers. The sprinkler produces large water droplets through the use of an extra-large orifice and a special double deflector. The large water droplets provide the required mass to penetrate the fire plume of severe fires. This characteristic permits direct wetting of the burning fuel while cooling the atmosphere and can eliminate the requirement for in-rack sprinklers in certain cases. Viking VK540 Upright CMSA 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).
