What components of a water spray fixed system are often found in either automatic or open configurations?

In a water spray fixed system, nozzles play a critical role and can be found in both automatic and open configurations. The primary function of nozzles is to disperse water in a controlled manner to effectively suppress fire. In automatic systems, these nozzles are designed to activate upon detecting heat or flame, ensuring a timely response to a fire situation. In contrast, open nozzles allow for continuous water flow, providing a blanket of protection over designated areas. The versatility and functionality of nozzles make them essential components in ensuring that the system can respond appropriately, depending on the configuration and the specific fire protection needs.

While pipes, valves, and controls are also important elements of fire protection systems, their roles differ. Pipes serve as conduits for transporting water, valves are used for controlling the flow, and controls manage the system's operation; however, it is the nozzles that directly impact how effectively water is applied to extinguish flames in various configurations.
