Thermotech 302-194 194°F Rate-Anticipation Heat Detector, Internal Vertical Mounting

Deliver fast, dependable fire detection where it matters most. The Thermotech 302-194 rate-anticipation heat detector is engineered to provide rapid, false-alarm resistant protection for commercial and industrial interior spaces. As a wired heat detector with a 194°F fixed-temperature setting and rate-of-rise compensation, it reacts to rapid temperature increases 1–3°F ahead of the nominal set point while ignoring brief, non-hazardous temperature spikes—minimizing nuisance alarms and unnecessary interruptions to operations. Its internal vertical mounting and ceiling-compatible form factor make installation straightforward in retrofit and new-build fire alarm systems. Built hermetically sealed and resistant to shock and corrosion, the 302-194 is designed for long-term reliability and low maintenance, and it automatically resets when temperatures return below the threshold. Ideal for integration with security, surveillance, and building monitoring systems where prompt, accurate fire detection is critical.
