US VSR-2.5 is a vane type waterflow switch designed for installation in 2.5-inch water supply piping used in fire protection and sprinkler systems. When water flows through the pipe, the internal paddle vane deflects and actuates an electrical switch, signaling flow to a fire alarm control panel or monitoring system. This device is a core component in wet-pipe sprinkler systems, providing reliable detection of waterflow events. Installation is performed by licensed fire protection contractors or qualified plumbing and mechanical technicians working to applicable codes.\u003c\/p\u003e\n\u003cp\u003eThe VSR-2.5 is used in commercial and residential fire suppression systems where 2.5-inch wet-pipe sprinkler mains are present. It is typically installed in horizontal or vertical pipe runs and wired into a fire alarm control panel to initiate alarm signals upon sprinkler activation or pipe flow. This switch is categorized under waterflow equipment and is sold as an individual unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVane-actuated paddle design responds to waterflow in 2.5-inch pipe\u003c\/li\u003e\n  \u003cli\u003eGenerates an electrical signal upon flow detection for integration with fire alarm panels\u003c\/li\u003e\n  \u003cli\u003eDesigned for wet-pipe fire sprinkler system applications\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for straightforward replacement or new installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style waterflow switch for use in wet-pipe fire sprinkler systems with 2.5-inch piping.

Shut down and drain the affected sprinkler system branch before cutting into the pipe for saddle or tee installation. Wiring connections to the fire alarm control panel must comply with NFPA 72 and applicable NEC low-voltage wiring requirements. Do not install in pressurized or active pipe without completing the required system isolation and impairment notification procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Vane type waterflow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Wet-pipe fire sprinkler systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: POTTER ELECTRIC SIGNAL CO.
