Model V-SD (Single Directional) Specific Application Attic Sprinkler

Model V-SD (Single Directional) Specific Application Attic Sprinkler

The Viking Model V-SD (Single Directional) Attic Sprinkler is UL Listed for both wet and dry pipe systems in combustible and non-combustible sloped attic spaces, and can be installed with steel or CPVC piping. (CPVC is allowed on wet pipe systems only.) When used with Viking's Model  V-BB (Back to Back) and VK696 Attic Upright sprinklers, it is possible to utilize a single line of piping at the attic peak, eliminating the need for branch lines and greatly reducing the number of required sprinklers and associated materials. The Model V-SD is a glass bulb design with a temperature rating of 200° F, and is offered in either standard brass or ENT plating for areas subject to corrosion.

The Model V-SD (Single Directional) sprinkler provides a reduced response time due to its narrow ridge spacing of 6 ft. (1,8 m) and long throw pattern (up to 40 ft. in a single direction measured horizontally) and is offered in three different slope ranges and one orifice size (K=5.6). Listed for specific pitches 4:12<7:12, 7:12<10:12 and 10:12≤12:12, and spans 40 ft. and 30 ft.
