It uses an electrochemical CO sensor, widely regarded as the most accurate sensing technology available for this application. The unit produces an 85 dB audio alarm at 10 feet and includes a rapidly flashing red indicator light when CO is detected. A front-access battery compartment simplifies servicing without removing the unit from its mounting location. The co400b is suitable for installations that must meet state and local carbon monoxide alarm codes.\u003c\/p\u003e\n\u003cp\u003eThe co400b is intended for residential use in homes, apartments, and similar occupancies where a standalone, battery-powered CO alarm is required by code. Because it operates entirely on a 9-volt alkaline battery, it requires no hardwire connection and can be placed in locations where AC wiring is not available or practical. The operating temperature range of 40 degrees F to 100 degrees F and a humidity range of 10 to 90 percent RH makes it suitable for typical interior living spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eElectrochemical CO sensor for accurate carbon monoxide detection\u003c\/li\u003e\n  \u003cli\u003e85 dB audio alarm at 10 feet with four-beep, pause, four-beep pattern\u003c\/li\u003e\n  \u003cli\u003eFront-access battery compartment for easy battery replacement without dismounting\u003c\/li\u003e\n  \u003cli\u003eSingle-button Test\/Silence function electronically simulates CO conditions to verify operation\u003c\/li\u003e\n  \u003cli\u003eTwo silence modes: suppresses low-battery chirp for up to eight hours or temporarily clears nuisance alarms\u003c\/li\u003e\n  \u003cli\u003eEnd-of-life signal provides audible notification when the unit requires replacement\u003c\/li\u003e\n  \u003cli\u003e7-year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standalone battery-operated carbon monoxide alarm for residential occupancies requiring compliance with state and local CO alarm codes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed electrician or qualified contractor, though many jurisdictions permit homeowner installation of battery-only CO alarms. Follow NFPA 720 and applicable local codes for placement height and room-coverage requirements. No hardwire or low-voltage connections are required for this unit. Test the alarm immediately after installation and replace the 9-volt alkaline battery according to the manufacturer schedule.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 9V Alkaline Battery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAudio Alarm\u003c\/strong\u003e: 85 dB at 10 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCO Sensor Type\u003c\/strong\u003e: Electrochemical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 40 degrees F (4 degrees C) to 100 degrees F (38 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHumidity Range\u003c\/strong\u003e: 10% to 90% relative humidity (RH)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 3.3 inches H x 4.8 inches L x 1.5 inches D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlarm Reset\u003c\/strong\u003e: Automatic when CO clears\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 7-Year Limited\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: BRK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: co400b\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRK","offers":[{"title":"Default Title","offer_id":51161948913970,"sku":"CO400B","price":29.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/306255056.png?v=1778886684","url":"https:\/\/voomisupply.com\/products\/brk-co400b-carbon-monoxide-alarm-9v-battery-operated","provider":"Voomi Supply","version":"1.0","type":"link"}
