Fenwal 27121-0-190 Thermal Heat Fire Detector

Fenwal 27121-0-190 Detect-A-Fire Thermal Heat Fire Detector is a heat-activated fire alarm sensor designed for integration into standard fire alarm systems. This device uses a fixed 190° heat threshold to trigger an alarm and is identified by model number 27121-0-190 within Fenwal’s Detect-A-Fire line. As a thermal detector, it provides rapid response to elevated temperatures, offering an alternative or supplement to smoke-based detection in installations where heat is a more reliable indicator of fire risk. The detector is intended to be installed as part of a building’s alarm circuitry, signaling the control panel to warn occupants and initiate appropriate safety procedures. Key attributes to note are its thermal detection function and 190° rating, which influence compatibility with corresponding fire alarm panels and system configurations.
