Kidde-Fenwal KS-HD

The Kidde-Fenwal KS-HD is a fixed temperature heat detector designed for addressable fire alarm systems, featuring an alarm threshold set at 135°F. This intelligent device makes independent alarm decisions based on continuous analysis of its thermal sensor, incorporating high-impact polymer construction for durability in commercial and industrial environments where reliable early heat detection is critical. Unlike conventional detectors requiring panel-level processing, the KS-HD's addressable design allows each detector to provide real-time status reporting back to the control panel, enabling faster response to developing fire conditions and more precise system diagnostics.
