The Thermotech 302 Series Rate Compensation Heat Detectors are normally-open devices designed especially for fire detection and alarm systems. The 302 Series operates 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 or 194° F ratings.
Initiates an immediate response. The 302 Series activates whenever ambient air temperature reaches a detector's 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.
Supports universal application. The 302 Series can be used in all areas for any type of occupancy.
Built with a hermetically sealed, shock resistant corrosion resistant, and tamper-proof.
