Kidde Fenwal 27121-0-500 DETECT-A-FIRE Detection and Release Device, Vertical Configuration, 500F Setting, Brass Head

Deliver fast, reliable heat-activated protection where robust, maintenance-light detection is required. The Kidde Fenwal DETECT-A-FIRE heat detector (vertical configuration, 500°F setting) is engineered for dependable activation of fire suppression and alarm systems across industrial, commercial and critical security sites. Its rate-compensated sensing accurately tracks ambient temperature rise—providing consistent operation whether a fire grows slowly or rapidly—making it ideal for use with clean agent, CO2, inert gas, wet/dry chemical or water-based suppression. The brass head and hermetically sealed stainless steel internals ensure long-term durability in harsh environments while the factory-set 500°F threshold and self-restoring, testable design reduce commissioning time and ongoing maintenance. Integrate this heat detector into building monitoring, surveillance and security alarm systems to enhance protection for equipment rooms, storage areas, engine compartments and other high-risk zones. Specify Kidde Fenwal DETECT-A-FIRE for proven, low-maintenance heat detection that supports effective suppression activation—contact us to order or confirm compatibility with your fire protection system.
