Our products gain widespread trust in more than 100 countries globally. We’re a 20-year fire safety alarm maker providing reliable, innovative home hazard protection.

Our smoke alarms adopt 10-Year Sealed Lithium Batteries, so no battery replacement is required during the whole service life. Why does my detector keep going off for no reason? Most false alarms come from mounting location. Keep 10 ft from cooking, 3 ft from vents & bathrooms, 4 in from walls. Mount right — fewer alarms. Why Choose a Smoke & CO Detector Certified to UL 217 10th Ed. & UL 2034 5th Ed.? UL 217 10th Edition Improves Smoke Detection And Reduces Nuisance Alarms. UL 2034 5th Edition Ensures Accurate Carbon Monoxide Detection. ETL Listed To UL Latest Standards For Dependable 2-In-1 Home Safety. Approved for California's Strict Fire Safety Standards? Our Smoke Detector Is Officially Listed By The California State Fire Marshal (OSFM), Listing No. 7257-2402:0002, And Complies With California Title 19 And Title 24 Residential Fire Safety Requirements. Why Choose a Smoke & CO Detector with a 10-year Sealed Battery? More U.S. States Require 10-Year Sealed Battery Smoke Alarms Per NFPA 72 To Avoid Dead Or Removed Battery Hazards. Our UL 217 10th Edition Detector Has An Integrated Sealed Lithium Cell With Decade-Long Fire Monitoring And Zero Battery Swaps. Will the 2-In-1 Smoke & CO Alarm Help Reduce False Alarms? Yes. The Dual-Beam Photoelectric Sensor Minimizes Cooking-Related False Alarms, While The Independent CO Sensor Ensures Reliable Protection.
