Circle Slash Inside Square of Sprinkler System Diagram

Squares in a sprinkler system diagram represent equipment or components, circles represent connections or interfaces, and a slash indicates that the connection or interface is closed or disabled. Typically, a square represents a device or component, and a circle represents an interface to that device or component. This type of icon is often used in engineering drawings to show the composition and connectivity of complex systems. In the case of a sprinkler system, a square may represent a sprinkler head, valve, pump, or other piece of equipment, while a circle represents a piping connection to that piece of equipment. A slash indicates that a connection or interface is closed, i.e., there is no connection or no pathway. Based on the specific details on the diagram, the exact meaning of the circle-slash-bar inside the square can be determined.
