Overview
The Viking™ VK796 C-1 Window Sprinkler (Part Number 01326BF) is a high-capacity, open-type sprinkler designed for use in deluge fire protection systems. It provides dependable protection for windows, walls, and roofs exposed to flames or radiant heat from nearby structures or fires. When the system activates, this sprinkler releases a wide, fan-shaped sheet of water that forms a protective curtain, helping to block heat and stop flames from spreading through unprotected openings.
Built from solid brass and finished with a durable chrome coating, the VK796 combines corrosion resistance with a polished, professional appearance. It features a 3/4-inch NPT connection and a 3/4-inch orifice that deliver an 8.1K discharge factor for strong, even water flow. This large capacity makes it ideal for protecting wide or high-risk areas where reliable water coverage is essential.
Product Overview
The VK796 C-1 Window Sprinkler produces a 180-degree fan-shaped spray pattern that spreads water evenly across a window, wall, or façade surface. The water curtain helps cool the surface and prevents heat and flames from passing through. The sprinkler operates effectively with as little as 7 psi of water pressure and can safely withstand up to 175 psi, ensuring dependable performance in a wide range of system conditions.
The precision-engineered brass deflector ensures a smooth and uniform spray pattern, creating consistent protection across the entire surface. In a typical deluge system, several sprinklers are installed side by side along a wall or opening so their sprays overlap slightly. This overlapping design forms a solid barrier of water that helps prevent fire spread and limits radiant heat exposure to nearby structures.
The VK796’s chrome finish adds an extra layer of corrosion resistance and a clean appearance, making it suitable for installations where the sprinkler is visible. It’s commonly used in commercial, industrial, and architectural applications such as exterior façades, glass walls, and large openings that face heat exposure risks.
Listings and Approvals
The Viking™ VK796 C-1 Window Sprinkler is UL Listed for use in fixed fire protection systems. This certification confirms that it meets strict performance and safety standards for deluge system sprinklers. While not FM Approved, the VK796 offers the same high-quality construction and proven performance as other sprinklers in Viking’s C-1 Window Sprinkler line. Each unit is tested to ensure consistent water flow, pressure durability, and even spray distribution.
Installers and system designers should follow Viking’s official technical data and all applicable fire protection codes to ensure correct installation and compliance with local requirements.
Installation and Maintenance
The VK796 must be installed in the exact position and orientation shown on the approved design drawings. The sprinkler’s deflector should face the surface being protected, allowing the spray to form a 180-degree fan pattern that covers the entire window or wall. Use only the manufacturer’s specified wrench when installing, and apply the proper torque to prevent leaks or thread damage. Keep the waterway clean during installation and remove any temporary protective covers before testing the system.
Once installed, the sprinkler should be inspected regularly as part of routine fire protection maintenance. Check that the deflector and openings remain clear of dirt, paint, or corrosion, and confirm that there are no obstructions to the spray pattern. Any sprinkler that is bent, damaged, or corroded should be replaced immediately. Routine system inspections and flow tests, as required by NFPA 25 or local codes, help ensure continued performance and reliability.
With its strong 8.1K discharge factor, corrosion-resistant chrome finish, and wide 180-degree fan-shaped spray, the Viking™ VK796 C-1 Window Sprinkler provides powerful and reliable protection for large or exposed openings. It is a proven solution for deluge systems that demand high-volume water delivery and consistent fire exposure control.
