Rate Compensation Heat Detectors
Series 302 heat detectors are designed for use in normal environments as well as environments
where the detectors are subject to weather, moisture (internal condensation), and explosive
atmospheres. They are normally-open devices designed to close an electrical circuit upon
activation. All models feature rate compensation and are available with either 135 °F (57.2 °C)
or 194 °F (90 °C) ratings. They are self restoring, hermetically sealed, shock and corrosion
resistant, and are tamperproof.

The sensor's aluminum tube acts as a heat collector when sources of heat radiate directly
on the tube. Install these sensors out of direct sunlight and away from radiating heat sources
including the direct flow from heaters and heat ducts.
