1. DESCRIPTION

Viking Freedom

Residential Concealed Horizontal Sidewall Sprinkler VK490

is a small high-sensitivity solder link and lever residential sprinkler designed for

installation on concealed pipe systems, where the appearance of a smooth wall is

desired. The sprinkler orifice design, with a K-Factor of 5.8 (83.6 metric*), allows

the sprinkler’s efficient use of available water supplies for the hydraulically designed

fire-protection system. The operating element and special deflector characteristics

meet the challenges of residential sprinkler standards.

The sprinkler is hidden from view by a low profile, small diameter cover plate

installed flush to the wall. The cover plate is available in several decorative finishes

to meet design requirements. The two-piece design allows installation and testing of

the sprinkler prior to installation of the cover plate. After the system has been tested

and wall finish has been applied, the push-on design of the cover plate assembly

allows easy installation of the cover plate with up to 1/4” (6.4 mm) adjustment.

Sprinkler VK490 is provided with a pipe guide to properly locate the sprinkler and

allow the 1/4” adjustment of the cover plate.
