It monitors NO2 concentrations in the ambient environment and transmits readings back to the controller for alarming and system response. This sensor is typically installed by licensed HVAC technicians or building automation contractors in commercial or light-industrial settings where combustion byproducts or vehicle exhaust require continuous monitoring. The S301D2NO2 is a field-mounted remote unit, keeping detection at the point of concern while the controller handles logic and output functions.\u003c\/p\u003e\n\u003cp\u003eThis sensor is suited for applications where nitrogen dioxide exposure is a safety concern, such as parking garages, loading docks, mechanical rooms, and other enclosed spaces with combustion sources. It pairs specifically with the 301EM controller, which manages alarm thresholds, relay outputs, and system responses based on sensor input. Installation in commercial environments typically follows local building codes and ASHRAE ventilation standards for hazardous gas detection systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDetects nitrogen dioxide gas for continuous ambient air quality monitoring\u003c\/li\u003e\n  \u003cli\u003eRemote sensor design keeps detection at the source while the controller remains centrally located\u003c\/li\u003e\n  \u003cli\u003eDesigned to pair with the Honeywell 301EM gas detection controller\u003c\/li\u003e\n  \u003cli\u003eSuitable for commercial and light-industrial indoor environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the Honeywell 301EM gas detection controller as a remote NO2 sensing module.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with gas detection systems and applicable local codes. Power down the 301EM controller before connecting or disconnecting the remote sensor. Mount the sensor at the appropriate height for nitrogen dioxide detection per the controller documentation and site requirements. Follow all wiring guidelines provided with the 301EM controller and verify proper system operation after installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Type\u003c\/strong\u003e: Nitrogen Dioxide (NO2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: Remote\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Controller\u003c\/strong\u003e: 301EM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HONEYWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S301D2NO2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51284028096818,"sku":"129432-L3","price":2165.02,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279131.jpg?v=1781066523","url":"https:\/\/voomisupply.com\/products\/honeywell-s301d2no2-no2-remote-sensor-301em","provider":"Voomi Supply","version":"1.0","type":"link"}
