Rate Compensation Heat Detectors 302 Series

Manufacture: kidde
Product code: 302 Series

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.

Application

Sensors rated at 135 °F (57.2 °C) will not respond to momentary temperature fluctuations less than 30 °F/minute between 60 °F (16 °C) and 100 °F (38 °C). Sensors rated at 194°F (90 °C) will not respond to momentary temperature fluctuations less than 50 °F/minute between 60 °F (16 °C) and 150 °F (66 °C). 302 Series sensors should not be used in environments where conditions exceed these parameters. Do not install them in hot air ducts, in front of heaters, in paint booths that use heat to cure paint, or any other location subject to temperature fluctuation.

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 radiating heat sources including the direct flow heaters and heat ducts.
