It uses photoelectric smoke sensing technology to detect smoke particles from smoldering fires and an electrochemical sensor to detect carbon monoxide, providing dual-threat protection in a single unit. The slim profile measures 5.67 inches by 5.67 inches with a 1-inch height, allowing it to sit flush and blend with standard residential ceilings. Power comes from included AA alkaline batteries, which are user-replaceable, making this unit fully self-contained without requiring hardwired connections. Licensed electricians, HVAC technicians, and general contractors install this type of alarm as part of new construction or retrofit life-safety upgrades.\u003c\/p\u003e\u003cp\u003eThis alarm is suited for residential applications including bedrooms, hallways, and living areas where combination smoke and CO detection is required by local codes. The photoelectric sensor is particularly effective in rooms prone to slow, smoldering fire conditions, while the electrochemical CO sensor responds to carbon monoxide buildup from combustion appliances such as gas furnaces, water heaters, and attached garages. The slim profile design makes it appropriate for spaces where standard-depth alarms would be visually intrusive. The one-touch test and silence button allows quick silencing of nuisance alarms from cooking without disabling protection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePhotoelectric smoke sensor detects smoke particles from smoldering fires with reduced cooking nuisance alarms\u003c\/li\u003e\n\u003cli\u003eElectrochemical CO sensor provides early carbon monoxide detection\u003c\/li\u003e\n\u003cli\u003eSlim profile at 1 inch height fits flush against ceilings and walls\u003c\/li\u003e\n\u003cli\u003eAA alkaline batteries included and user-replaceable — no hardwiring required\u003c\/li\u003e\n\u003cli\u003eEnd-of-life warning signal provides audible notice when the unit must be replaced\u003c\/li\u003e\n\u003cli\u003eOne-touch test and silence button for quick nuisance alarm management\u003c\/li\u003e\n\u003cli\u003e85 dB alarm output at 10 feet meets standard residential audibility requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 1046794 is an OEM-style replacement for the PC1200. It is designed for residential combination smoke and CO alarm applications. Refer to local fire and building codes to confirm placement and quantity requirements for the installation location.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed in accordance with NFPA 72 and applicable local building and fire codes. Power down or remove battery sources from any adjacent interconnected alarms before servicing existing units. Mount the alarm to a clean, flat surface using the provided hardware, following the manufacturer placement guidelines for ceiling or wall positioning relative to sleeping areas and combustion appliance locations. Do not install in areas subject to extreme humidity, condensation, or temperatures outside the rated operating range, as this can affect sensor accuracy and alarm performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: Electrochemical, Photoelectric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply\u003c\/strong\u003e: Battery Operated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Type\u003c\/strong\u003e: AA Alkaline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Replaceable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound Level\u003c\/strong\u003e: 85 dB at 10 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Length\u003c\/strong\u003e: 5.67 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Width\u003c\/strong\u003e: 5.67 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 10 Years Limited\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RESIDEO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1046794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESIDEO","offers":[{"title":"Default Title","offer_id":51138424439090,"sku":"1046794","price":64.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533368.png?v=1778256058","url":"https:\/\/voomisupply.com\/products\/resideo-1046794-smoke-co-alarm-battery-operated-replaces-pc1200","provider":"Voomi Supply","version":"1.0","type":"link"}
