March 10, 2008—Viking, a global leader in fixed fire protection solutions, has expanded its Mirage line of commercial concealed sprinklers to include two new quick response, extended coverage products.
The new VK632 [5.6 (81) K factor] and VK634 [8.0 (115) K factor] sprinklers are cULus listed and FM approved for 135F (57C), 155F (68C), 175F (79C), and 200F (93C) temperature ratings.
Designed with the installer in mind, Viking’s Mirage flat-plate concealed sprinklers include an easy “push on, thread off” cover plate. The cover plate also installs on the inside of the sprinkler cup providing better protection from drywall mud, paint, and other debris. In addition to a smaller takeout dimension, the sprinklers deflector is aligned with the bottom of the sprinkler cup for easier calculation of drop lengths.
Viking also offers special tools for its Mirage line allowing the installer to remove the sprinklers’ protective caps and install cover plates from the floor, without the use of a ladder. The cap removal tool, which doubles as a “leave behind” wrench for the sprinkler cabinet, attaches to a length of one inch (DN25) CPVC, making it possible to remove the plastic caps from the floor.
Once the protective cap is removed, installers can use Vikings innovative cover plate installation tool. This tool, which attaches to the other end of the CPVC pipe length, enables the installation of cover plates without using a ladder.
Viking offers two cover plate options for its Mirage line. The standard cover plate, at 2-3/4 in. (70 mm) in diameter, is best suited for installations where esthetics are a priority. The large cover plate, 3-5/16 (84 mm) diameter, offers the greatest horizontal foregiveability for maximum installation flexibility. Both Mirage cover plate options are available in nine standard finishes as well as over 900 custom colors.
