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-EPM-135 is available with a 135°F (57.2°C) fixed temperature rating. It is an explosion proof detector with hexagonal grip bushing with 1/2″ conduit threads for attachment to threaded hub covers of series JL fixture fitting manufactured by Killark Electric Co., or equivalent. Must be hand tightened only. For indoor use only. The detectors are self-restoring, hermetically sealed, shock and corrosion resistant, and are tamperproof.
