Heat detectors are essential fire detection devices that respond to increases in temperature, making them ideal for environments where smoke detectors may cause false alarms, such as kitchens, garages, attics, and industrial areas with dust or fumes. Our inventory includes rate-of-rise heat detectors, fixed-temperature models (135°F and other ratings), addressable photo\/thermal combination detectors, and explosion-proof models for hazardous locations.

The Thermotech 302 Series rate-anticipation heat detectors operate within a controlled range of two to three degrees of their set points, regardless of the speed or rate of temperature rise. These detectors are available in either 135°F (57.2°C) or 194°F (90°C) ratings. The 302 Series are normally open devices designed especially for fire detection and alarm systems.
Main Features
Self-restoring.
Hermetically sealed. Shock resistant, corrosion resistant, and tamper-proof.
I mmediate response. The 302 Series activateWhenever ambient air temperature reaches a detectors setting, eliminating the thermal time lag inherent in conventional heat detectors.
Eliminates false alarms. The 302 Series do not respond to momentary temperature fluctuations below the selected temperature.
Universal application. The 302 Series can be used in all areas for any type of occupancy.
Can be used in all areas for any type of occupancy
