Potter Electric Signal Co. Us WLS Universal Switch

Product Description

The POTTER ELECTRIC SIGNAL CO. 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.
