The electrochemical CO sensor continuously monitors air quality and displays both ambient temperature and current and peak carbon monoxide concentrations on screen. Because the battery is built in and rated for the full lifetime of the unit, there are no battery replacements required during service life. When CO levels reach a dangerous threshold, an 85 decibel horn sounds to alert occupants. This detector is installed by electricians, HVAC technicians, and general contractors as part of residential safety compliance.\u003c\/p\u003e\u003cp\u003eThe 1039753 is designed for tabletop or dresser-top placement in residential settings including bedrooms, living areas, and hotel or rental units. The freestanding form factor requires no wall mounting, making placement flexible and repositioning straightforward. The backlit display provides at-a-glance readout of temperature alongside CO readings, giving occupants and service professionals immediate situational data. A test and silence button allows functionality verification and alarm silencing during nuisance events.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eElectrochemical CO sensor with up to 10-year detection life\u003c\/li\u003e\n\u003cli\u003eSealed 10-year lithium battery — no battery changes required\u003c\/li\u003e\n\u003cli\u003eBacklit digital display shows ambient temperature plus current and peak CO concentrations\u003c\/li\u003e\n\u003cli\u003e85 decibel alarm horn activates when CO reaches dangerous levels\u003c\/li\u003e\n\u003cli\u003eTest and silence button for functional verification and alarm silencing\u003c\/li\u003e\n\u003cli\u003eFreestanding tabletop design — no wall mounting hardware required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a freestanding residential carbon monoxide detector suitable for tabletop placement in homes, apartments, and similar occupied spaces where CO monitoring is required by code.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePlacement and installation of CO detectors in residential occupancies is governed by local building codes and NFPA 720 guidelines — verify local requirements before deployment. No wiring is required for this battery-operated unit; simply place on a stable flat surface away from cooking appliances and direct airflow sources that can cause nuisance trips. Test the unit using the test button immediately after placement and at regular intervals per the manufacturer schedule. Dispose of the sealed lithium battery in accordance with local regulations at end of product life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: Electrochemical carbon monoxide sensor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: Sealed 10-year lithium, built-in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlarm Sound Level\u003c\/strong\u003e: 85 decibels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: Backlit digital — ambient temperature, current CO concentration, peak CO concentration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Height\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Width\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Depth\u003c\/strong\u003e: 1.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 7.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FIRST ALERT BRK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1039753\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FIRST ALERT","offers":[{"title":"Default Title","offer_id":51711427117362,"sku":"1039753","price":211.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dd296356c5d45741df9396ed079300a.jpg?v=1788476535","url":"https:\/\/voomisupply.com\/products\/first-alert-brk-1039753-co-detector-10-year-battery","provider":"Voomi Supply","version":"1.0","type":"link"}
