Overview
The Viking™ VK792 C-1 Window Sprinkler (Part Number 01322BA) is a high-performance, open-type sprinkler designed for use in deluge fire protection systems. It provides reliable protection for windows, walls, and roofs that could be exposed to flames or radiant heat from nearby fires. When the system is activated, the sprinkler releases a wide, fan-shaped sheet of water that acts as a curtain to help block heat, absorb energy, and prevent the spread of fire through glass or other exposed openings.
Made from durable brass, the VK792 combines strength, corrosion resistance, and lasting performance in both indoor and outdoor settings. Its 1/2-inch NPT connection and 3/8-inch orifice produce a 3.0K discharge factor, offering increased water flow compared to smaller models. This higher output makes it well-suited for larger openings and applications that need stronger water coverage to protect against heat exposure.
Product Overview
The VK792 C-1 Window Sprinkler creates a 180-degree fan-shaped spray pattern that spreads water evenly across the surface of a window or wall. This continuous water curtain helps cool exposed surfaces and shields them from radiant heat, reducing the chance of glass breakage or flame penetration. The sprinkler performs effectively with as little as 7 psi of pressure and can handle up to 175 psi, allowing it to function in a variety of system designs and site conditions.
The precision-engineered brass deflector ensures an even spray pattern and stable water distribution. In most installations, several sprinklers are spaced along a wall or window so that their water fans overlap, forming a solid line of protection. This continuous curtain is key to stopping flames or heat from spreading from one structure to another.
With its dependable performance and corrosion-resistant design, the VK792 is often used in industrial facilities, warehouses, refineries, and other settings where radiant heat exposure poses a serious risk. It also provides strong, consistent protection for tunnels, canopies, and exterior walls exposed to potential fire hazards.
Listings and Approvals
The Viking™ VK792 C-1 Window Sprinkler is both UL Listed and FM Approved for use in fixed fire protection systems. These approvals confirm that the sprinkler meets strict standards for reliability, spray performance, and structural strength. Each unit is tested to ensure that it delivers consistent, even water coverage at the rated pressures and that it performs effectively during demanding fire conditions.
Installers and designers should follow the manufacturer’s published technical data and comply with all applicable codes and standards when selecting and installing this model. Proper use ensures the VK792 provides the intended level of fire exposure protection.
Installation and Maintenance
The VK792 must be installed in the correct orientation to ensure that the water spray covers the intended surface. The deflector should face outward to project the 180-degree fan pattern evenly across the window or wall. Only the manufacturer’s recommended wrench should be used for installation, and the sprinkler should be tightened to the specified torque to prevent leaks or damage. Keep the sprinkler’s waterway clean during installation, and remove any protective covers or caps before testing.
Once installed, the sprinkler should be inspected and maintained regularly as part of the building’s fire protection program. Check that the deflector and orifice are free from paint, dirt, or corrosion, and make sure no objects block the spray path. Any sprinkler that is bent, corroded, or blocked should be replaced immediately with an identical model.
With its strong brass construction, high flow capability, and wide 180-degree spray pattern, the Viking™ VK792 C-1 Window Sprinkler provides reliable protection for windows and other openings exposed to fire risk. It’s a proven choice for deluge systems that need effective, large-area water coverage to stop heat and flame spread before damage can occur.
