Edwards Signaling All Weather Heat Detector - Explosion Proof Mounting

Edwards SD-SJ is a sensor for the SuperDuct smoke detectors. Designed for interconnection to detectors using terminal connections.

The NGD269 is ideal for checking automotive exhaust and fuel systems, liquid- and gas-fired heating systems, propane tanks and filling stations, cracked heat exchangers and manholes/sewers. Detects the presence of most combustible gases without measuring or displaying their concentration. The unit's analog bar graph, and the speed and tone of its audible alarm, enable the NGD269 to pinpoint the location of a gas leak by comparing its responses to gas exposure at different points. Measures and displays the concentration of CH4 (methane/natural gas), C3H8 (propane) and H2 (hydrogen) for ...

Edwards SD-CJ is a controller for the SuperDuct smoke detectors. Designed for interconnection to detectors using RJ45 wiring harnesses.

The Triplett Model GSM100 Combustible Gas Detector identifies the presence of combustible gases such as Methane, Hydrogen, Carbon Monoxide, Propane, Ethylene, Ethane, Hexane, Benzene, Iso-Butane, Ethanol, Acetaldehyde, Formaldehyde, Toluene, P-Xylene, Ammonia, and Hydrogen Sulfide. It will also detect common mixtures that would include or emit more than one of these gases: Natural Gas (typically consists of a high percentage of methane and smaller percentages of propane and other gases), Paint Thinners, Industrial Solvents, Dry Cleaning Fluids, and Gasoline. The GSM100 has a 16" (406mm) ...

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-135 is available with a 135°F (57.2°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 ...
