The 302-ET-194 is calibrated to 194°F and is suited for spaces where ambient temperatures regularly approach the lower 135°F detector range. The rate-compensated design prevents false actuation from slow ambient temperature changes while maintaining reliable response to rapid fire-generated heat. Applications include loading docks, canopy structures, transformer enclosures, and exterior equipment areas. Total overall length: 4⅛ inches (Model 302 series).\u003c\/p\u003e\n\u003cp\u003eVerify panel\/device family compatibility before ordering.\u003c\/p\u003e","brand":"Thermotech","offers":[{"title":"Default Title","offer_id":51562189685029,"sku":"302-ET-194","price":39.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/7648\/4645\/files\/thermotech-heat-detectors-default-title-thermotech-302-et-194-all-weather-heat-detector-194-f-34752329679072.jpg?v=1771297425","url":"https:\/\/fastalarmdistribution.com\/products\/thermotech-302-et-194-194-f-all-weather-heat-detector","provider":"Fast Alarm Distribution","version":"1.0","type":"link"}
