The reliability of this system hinges significantly on proper installation and wiring. Understanding the “fire alarm flow switch wiring diagram” is therefore essential for electricians and fire safety technicians. The primary keyword focuses on the wiring diagram, which is a noun phrase, acting as the core subject matter for understanding the connection and operation of the flow switch.
