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. The 302-AW-194 is available with a 194&#176;F (90&#176;C) fixed temperature rating. It is an all-weather heat detector designed for moisture proof or dust proof installations. Requires no special back box when the all-weather leads are properly spliced to "THW" or equivalent type wire and splices are moisture proof. For indoor or outdoor use. The detectors are self-restoring, hermetically sealed, shock and corrosion resistant, and are tamperproof.<br><br>
