USI 8th Generation Smoke Detector meets the latest industry standards.
The USI AMIL3051SC Living Room Smoke Alarm with a 10-year sealed battery is specifically engineered to provide superior protection in your home's main living spaces. These areas, which include living rooms and hallways, are often the primary gathering points for families, making them crucial locations for fire detection. The alarm's battery-operated design allows for easy, wire-free installation and flexible placement, ensuring you can position it for optimal coverage without being restricted by your home's electrical layout. Its 10-year sealed battery is a game-changer, offering a decade of continuous protection with zero battery changes. This not only provides long-term peace of mind but also eliminates the common hassle of low-battery chirps and the risk of a non-functional alarm due to a neglected battery.
A key differentiator for the AMIL3051SC is its Sensing Plus Technology, which makes it particularly well-suited for a living area environment. This advanced, multi-criteria detection system combines the best of both photoelectric and ionization sensing into a single, intelligent device. Using artificial intelligence, the alarm can more accurately differentiate between real smoke from a fire and nuisance alarms caused by common household events like a smoking fireplace or dust. This microprocessor-driven intelligence significantly reduces the chances of false alarms, which can be a major source of frustration and lead to alarms being disabled. By providing a smart, reliable, and hassle-free solution for a full 10 years, the AMIL3051SC offers a new standard in home safety, ensuring your main living areas are protected with a sophisticated and dependable alarm.
10 Year Permanent Power also saves money from battery replacements (up to $38.00 over the 10-year life of the alarm), eliminates annoying low battery chirps and helps the environment by reducing environmental waste from disposed batteries. This smoke and fire detector features microprocessor intelligence that assists in completely eliminating nuisance alarms, a single silence/test button to quiet a non-hazardous alarm and an end-of-service life warning that sounds when it's time to replace the smoke detector's battery (approximately 10-years from activation).
Perfect for replacing existing USI Smoke Detectors, this smoke and fire alarm features a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick activation battery pull tab makes it easy to install while the deactivation key switches the alarm off and makes the batteries safe for disposal. Once the 10 year smoke and fire alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

Meets New Laws & Legislations
This alarm exceeds industry standards, and is listed to UL Standard UL 217 8th Edition and is California State Fire Marshal approved.
Battery smoke alarms are a simple yet highly effective way to provide crucial fire protection for any home. Unlike hardwired alarms that are permanently connected to a building's electrical system, battery alarms are completely self-contained, drawing all their power from a single, internal battery. This design provides maximum flexibility and convenience, as the alarms can be installed in virtually any location without the need for an electrical outlet or complex wiring. They are a popular choice for renters, those living in older homes without modern electrical systems, or for anyone looking to quickly enhance their home's safety by adding an alarm to a new location. While some models still rely on replaceable batteries that must be changed annually, modern technology has introduced advanced 10-year sealed battery models that offer a decade of maintenance-free, continuous protection, eliminating the risk of a dead battery.
Advantages of a Battery Operated Smoke Alarm
- Ease of Installation: No wiring is required. You can simply mount it with a few screws and it's ready to go. This makes it a perfect DIY project for anyone, regardless of their electrical expertise.
- Flexible Placement: Because they are not tied to your home's electrical wiring, you can place them in a wide variety of locations, including older homes where wiring may be impractical or costly to install.
- Continued Operation During Power Outages: Unlike hardwired alarms that rely on a battery backup, a battery alarm will continue to function normally during a power failure, ensuring uninterrupted protection.
- Cost-Effective: The initial purchase price of a standard battery alarm is typically lower than a hardwired unit, and it saves you the expense of hiring an electrician for installation.
Advantages of a 10 Year Battery Operated Smoke Alarm
- Maintenance-Free for a Decade: With a sealed battery alarm, you never have to worry about replacing the battery for the entire 10-year lifespan of the alarm.
- Eliminates Low-Battery Chirps: A constant source of frustration for many homeowners, the low-battery chirp is completely eliminated. The alarm will only chirp with an "end-of-life" warning after 10 years, letting you know it's time to replace the entire unit.
- Tamper-Proof: Since the battery is sealed within the unit, it cannot be removed or tampered with. This ensures the alarm is always powered on and ready to detect smoke or fire, addressing a common safety risk.

10 Year Sealed Battery Living Room Smoke and Fire Alarm Reviews
Got it not that long ago, but it seems to work. no false alarms. installation was easy. Glad i'm not going to have to install new batteries!
No complaints about the smoke detectors. Haven't had a fire though, so hopefully I continue to not have complaints!
I purchased from USI because they were the only ones who made a smoke alarm with both ionization and photoelectric AND a carbon monoxide detector. I put these ionization/photoelectric detectors everywhere except our bedrooms. I put combination smoke and carbon monoxide detectors in the bedrooms Since these are all hardwired, I have piece of mind that any issue anywhere in my home will alert us no matter where we are. There was an issue with my first order where I made a mistake and customer service did a fantastic job of fixing my mistake and getting the correct items out to me. I will recommend these detectors to my friends and extended family because they are first rate products and because of the excellent customer service.
I needed to replace the cheap smoke detectors in my house and did a lot of research before purchasing these. I'm happy to have the protection of BOTH sensors smoke and fire and the ease and savings of a ten year battery. I've installed three so far and they seem to be in perfect working order!
I am pleased with the product & think it will provide better protection than the detector it replaced.
