10-Year Batter Detectors

Why choose HEIMAN?

We’re a 20-year fire safety alarm maker providing reliable, innovative home hazard protection.

Why choose an ETL Listed UL217 10th Ed. smoke alarm?

Uncertified alarms violate US fire codes and fail official inspections. Our alarm passes third-party tests under the latest UL217 10th Ed., offering reliable early fire alerts and full legal compliance for all US homes and rentals.

How often should I replace the smoke alarm battery?

Our smoke alarms adopt 10-Year Sealed Lithium Batteries, so no battery replacement is required during the whole service life.

【MOUNT IT RIGHT. FEWER FALSE ALARMS】 Keep 10 ft from cooking (even open kitchens), 3 ft from A/C vents & bathroom doors, 4 in from walls. Wrong placement is a leading cause.
【10-YEAR SEALED BATTERY WITH EOL ALERT】Built-in sealed lithium battery powers the alarm continuously for 10 years — no battery replacements needed. When the unit reaches end of life, a clear audible EOL alert notifies you it’s time to replace the detector, ensuring continuous protection throughout its full lifespan.
【UL 217 10TH EDITION & UL 2034 5TH EDITION CERTIFIED】Certified to the latest safety standards — UL 217 10th Edition and UL 2034 5th Edition. The 10th Edition introduces enhanced cooking nuisance immunity tests and stricter requirements for modern synthetic-fueled fires, delivering upgraded detection capabilities for today’s homes.
【PHOTOELECTRIC SMOKE & ELECTROCHEMICAL CO DETECTION】Dual-sensor protection in one device: a photoelectric smoke sensor with dual-LED optical chamber detects slow-smoldering fires while reducing cooking false alarms, and an electrochemical CO sensor monitors carbon monoxide levels from 0–2000 ppm with 1 ppm resolution. Smoke sensitivity: 1.65–2.29%/ft obscuration.
【ETL LISTED — 4 CERTIFICATIONS】Independently tested and certified to US standards (UL 217 Ed.10 + UL 2034 Ed.5) and Canadian standards (CAN/ULC S531 Ed.5 + CSA 6.19). 94V-0 flame-retardant housing.
【EASY INSTALL & RESIDENTIAL USE】Quick twist-and-click mounting bracket included — no wiring required. Compact 4.9-inch diameter fits neatly in any room. 85dB alarm with LED indicator and test/silence button. Suitable for bedrooms, living rooms, hallways, and other residential indoor spaces where both smoke and CO hazards may be present.
