Kidde Fenwal 12-E27121-020-04-0T DETECT-A-FIRE Vertical Detector, 190°F (88°C), Stainless-Steel Head, Close on Rise

Dependable early heat detection for mission-critical fire protection and monitoring. The Kidde Fenwal DETECT-A-FIRE vertical heat detector delivers precise, repeatable actuation at a 190°F (88°C) setpoint, making it ideal as the initial sensing element for clean agent, CO2, inert gas, chemical or water-based suppression systems. Its rate-compensated design combines fixed-temperature reliability with resistance to nuisance alarms caused by transient thermal gradients, improving overall surveillance and security system performance.

Built with a stainless-steel head and a rugged surface-mount form factor, this wired temperature sensor withstands shock and vibration for reliable operation in industrial, commercial and data center environments. The close-on-rise action ensures positive signaling during rapidly developing events, while the self-restoring construction reduces maintenance and lifecycle costs. RoHS-compliant and widely trusted across fire protection applications, the DETECT-A-FIRE 27121-0 integrates smoothly with existing monitoring and suppression control panels.
