US WLS is a universal switch designed for use with steel and wood links in waterflow detection applications. This device serves as a switching mechanism that integrates with sprinkler system components, triggering alarm or control circuits when waterflow is detected. Installed by licensed fire protection contractors and licensed electricians, the WLS is suited for commercial and industrial fire suppression systems where reliable waterflow signaling is required. Its universal design allows it to work across a range of link types, making it a practical replacement or addition to existing waterflow equipment installations.\u003c\/p\u003e\n\u003cp\u003eThe WLS is applied in waterflow equipment assemblies within wet-pipe and dry-pipe sprinkler systems. It is used in commercial buildings, industrial facilities, and similar occupancies where code-compliant waterflow detection is required. The switch interfaces with the mechanical link assembly of the sprinkler riser or branch line, providing an electrical signal output to a fire alarm control panel or monitoring system when flow conditions are met.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUniversal design compatible with both steel and wood link assemblies\u003c\/li\u003e\n  \u003cli\u003eProvides reliable electrical switching output for waterflow alarm circuits\u003c\/li\u003e\n  \u003cli\u003eSuited for commercial and industrial fire suppression system installations\u003c\/li\u003e\n  \u003cli\u003eDesigned for integration with fire alarm control panels and monitoring equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style universal replacement switch for waterflow equipment assemblies using steel or wood links in commercial fire suppression systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed fire protection contractor or qualified electrician in accordance with NFPA 13, NFPA 72, and applicable local codes.
