USI 10 Year Sealed Battery Hallway Combination Smoke and Carbon Monoxide Alarm With Sensing Plus Technology - AMICH3511SC

The USI AMICH3511SC 3-in-1 Sensing Plus^® Smoke, Fire & Carbon Monoxide Alarm provides 10 years of continuous protection against deadly threats in the home. New Sensing Plus^® Multi-Criteria Detection provides the benefits of both photoelectric and ionization alarms in one device to protect against fast flaming and slow smoldering fires. This combination detector also offers protection against the silent killer - carbon monoxide - making it a 3-in-1 alarm. The ideal addition for new or replacement installations, Universal Sensing Plus Alarms^® are suitable for houses, apartments and mobile homes in every room.

This 3-in-1 detector implements a 10 year lithium-free battery that will never have to be replaced throughout the life of the alarm, giving you a decade's worth in peace of mind even in the event of a power outage. 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 combination detector features microprocessor intelligence that offers superior false alarm resistance. 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 battery (approximately 10-years from activation) have also been included.

Perfect for replacing existing USI Alarms, Universal Security Sensing Plus^® Combination Detectors feature a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick activation battery pull tab allows for easy installation while the deactivation key switches the alarm off and makes the batteries safe for disposal. Once the 3-in-1 combination detector is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

Battery operated smoke and carbon monoxide alarms are a simple yet highly effective way to provide crucial smoke, fire and carbon monoxide poisoning 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.

• 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.

• 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.
