New Recessed Flush Dry Sprinkler Protects Light and Ordinary Hazard Occupancies

Wednesday, August 20, 2014


Hastings, Michigan, USA - Viking Corporation, a global leader in fire protection and life safety systems, announces the availability of its new Model VK482 “recessed flush” dry sprinkler. This new quick response pendent sprinkler, which has a 5.6 (81) K factor, is cULus Listed for both Light and Ordinary Hazard occupancies. The VK482 provides an aesthetically pleasing alternative to a concealed dry sprinkler for protecting unheated areas in many types of struc tures including nursing homes, restaurants, schools, and freezers.

An innovative feature of the new VK482 is that the sprinkler’s fusible element can be recessed up to ½ inch ( 12 mm) above the ceiling. This is an important advantage for many applications, including insulated freezers, where the possibility of a forklift damaging the sprinkler is a potential concern.

The new sprinkler is available with an optional insulating boot assembly, which can be used to satisfy NFPA 13 code requirements for sealing around the barrel of a sprinkler when protecting an insulated freezer with a wet pipe system. Viking has performed extensive testing to verify that the new VK482, when installed in this manner, still meet s the requirements of a Quick Response sprinkler. The key to achieving the required response time is that the sprinkler’s fusible element is exposed within the protected area, unlike with a flat plate concealed dry sprinkler.

The new VK482 recessed flush dry sprinkler is available in 165°F (74°C) and 205°F (96°C) temperature ratings. The 205°F (96°C) temperature is important for accommodating defrost cycles that are part of the regular maint enance schedule for fr eezers. The VK482 also includes an in novative escutcheon that hangs from extrusions on flush sprinkler’s body helping to ensure the escutcheon does not fall off due to vibrations , such as from a fork lift or from someone walking above the ceiling of the protected structure.
