Powered by Universal Security Instruments' patented Sensing Plus Multi-Criteria Detection Technology, this photoelectric smoke alarm accurately identifies both slow-burning smoldering fires and fast-flaming fires while helping to reduce nuisance alarms from everyday cooking smoke and shower steam. The hardwired 120V AC connection with 10-year embedded alkaline battery backup provides uninterrupted protection during power outages for the full service life of the alarm. Interconnection capability links this alarm to compatible USI devices throughout the home - when one alarm sounds, every connected device sounds together, delivering critical early warning across every level. The Quick-Find Alarm Origination feature identifies which alarm triggered the event, saving critical time during an emergency. Compact 5.6 inch diameter profile mounts flush to ceiling or wall. Compliant with UL 217 and ETL listed. Ideal for new residential construction, multifamily buildings, rental property upgrades, and contractors replacing legacy hardwired smoke alarms.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cstrong\u003eTop Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensing Plus Multi-Criteria Detection\u003c\/strong\u003e: Patented technology accurately identifies both slow-burning smoldering fires and fast-flaming fires while reducing nuisance alarms from cooking smoke and shower steam.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardwired 120V AC with 10-Year Battery Backup\u003c\/strong\u003e: Continuous protection during power outages for the full service life of the alarm, with embedded alkaline AA batteries (included, non-replaceable).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterconnectable Alarm Network\u003c\/strong\u003e: Links to compatible USI alarms throughout the home - when one alarm sounds, every connected device sounds together for synchronized early warning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Find Alarm Origination\u003c\/strong\u003e: Easily pinpoints which alarm triggered the event, saving critical response time during an emergency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhotoelectric Sensor Technology\u003c\/strong\u003e: Optimized for smoldering fires that are the leading cause of residential fire fatalities; conforms to UL 217 and ETL listed for professional installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Number\u003c\/td\u003e\n\u003ctd\u003eUSI\/SM\/HW10YR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAlarm Type\u003c\/td\u003e\n\u003ctd\u003eSmoke and Fire Alarm (Hardwired with 10-Year Battery Backup)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003ePhotoelectric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Technology\u003c\/td\u003e\n\u003ctd\u003eSensing Plus Multi-Criteria Detection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Source\u003c\/td\u003e\n\u003ctd\u003eHardwired 120V AC with 10-Year Battery Backup\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Chemistry\u003c\/td\u003e\n\u003ctd\u003eAlkaline AA (included, embedded, non-replaceable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Life\u003c\/td\u003e\n\u003ctd\u003e10 Years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterconnectivity\u003c\/td\u003e\n\u003ctd\u003eYes - compatible with other USI interconnectable alarms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuick-Find Alarm Origination\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e5.6 inch W x 1.6 inch H x 5.6 inch D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety Listing\u003c\/td\u003e\n\u003ctd\u003eETL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety Standards\u003c\/td\u003e\n\u003ctd\u003eUL 217\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaintenance Alert\u003c\/td\u003e\n\u003ctd\u003eReplace the fire alarm if it is exposed to heat, flames, heavy smoke or water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack Quantity\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eUniversal Security Instruments (USI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e10-Year Limited\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eUniversal Security Instruments (USI) is a leading U.S. designer and manufacturer of residential fire and life-safety alarms, headquartered in Owings Mills, Maryland.
