Ionization-type detectors respond quickly to fast-flaming fires, making them a standard choice for hallways, bedrooms, and common areas. The 9120B runs on 120V AC line power and includes a battery backup circuit so the unit remains operational during a power outage. Installation is typically performed by a licensed electrician in compliance with NFPA 72 and local fire codes.\u003c\/p\u003e\n\u003cp\u003eThis detector is suited for residential buildings, apartments, and light commercial spaces where hardwired smoke detection is required by code. The AC-powered design with battery backup meets common building and life-safety code requirements for new construction and renovation projects. Electricians and fire-alarm technicians are the primary installers for hardwired smoke detection devices of this type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIonization sensing technology for fast-flaming fire detection\u003c\/li\u003e\n  \u003cli\u003e120V AC line power with battery backup for continuous operation during outages\u003c\/li\u003e\n  \u003cli\u003eHardwired installation suitable for new construction and retrofit applications\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging for per-location replacement or installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for hardwired 120V AC ionization smoke detectors in residential and light commercial fire-detection systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NFPA 72, the National Electrical Code, and applicable local codes. Shut off the branch circuit breaker supplying the detector circuit before making any wiring connections. Do not defeat or leave disconnected the battery backup — it is required for code-compliant operation. Mount the detector per the manufacturer instructions regarding placement height and distance from walls, cooking appliances, and HVAC supply registers.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 120 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Backup\u003c\/strong\u003e: Battery backup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDetector Type\u003c\/strong\u003e: Ionization\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\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 ELECTRONICS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9120B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FIRST ALERT","offers":[{"title":"Default Title","offer_id":51557974638898,"sku":"9120B","price":18.76,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/brk-electronics-9120b-ionization-smoke-detector-120v-ac","provider":"Voomi Supply","version":"1.0","type":"link"}
