Simple Installation

Installed the two devices the day they were delivered. Installation was simple and easy. Took more time to grab a screwdriver and ladder than it took to install one. The instructions were more detailed than I needed, but, were very informative.

Excellent Product

An updated building code now requires CO detectors by every bedroom. We needed to add 2 more detectors to meet this requirement. We had replaced an expired existing detector a few months ago with this model and were very happy with it. So, with this new requirement, we used this model again. I look forward to NOT having to change the batteries for 10 years.

Loud and easy to install

These alarms are easy to install. During the testing I realized they are louder than my previous alarms. Fortunately I have not had to have them activate in an emergency situation.

Very satisfied

Invested in new detectors for whole house: hard wired smoke, smoke and CO with sealed battery backup, sealed battery smoke and CO. Had to rewire as different plug than older units. Took a few hours almost 20 units, but straightforward. Happy with decision, purchase, and products.

Happy to find a 3 in 1 detector

Not many dual sensor smoke/fire detectors out there, especially with a carbon monoxide detector.

Many of our alarms come with a 10-year sealed Permanent Power battery that never needs replacing during the 10 year life of the alarm. Batteries in non sealed alarms should be replaced at least once a year or when the low battery signal sounds. Permanent Power battery technology helps keep you safe, because working smoke alarms are an important factor in surviving a home fire.
Early detection of smoke, carbon monoxide, and natural gas is key to saving lives. The National Fire Protection Association (NFPA) recommends installing a smoke alarm on every level of your home, including finished attics and basements. You are also encouraged to install a smoke detector inside every bedroom and at the top of certain stairways.
You never know what kind of hazard will strike your home, or when. That's why we recommend technology that can detect carbon monoxide (CO) and natural gas as well as smoke and fire. You'll get the most protection from devices that can quickly and accurately detect and respond to a range of threats.
A smoke alarm that goes off when there's no emergency is annoying. According to the National Fire Protection Association (NFPA), such "nuisance alarms" are the leading reason why homeowners intentionally disable their smoke detectors. Yet doing so can be deadly. A survey conducted by the NFPA found that smoke alarms sounded in only half of the home fires reported to U.S. fire departments, and almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms.
Yes, all USI Sensing Plus Detectors meet new UL 217 8th Edition requirements for smoke alarms

The USI AMIC3511SB 3-in-1 Sensing Plus® Smoke, Fire & Carbon Monoxide Detector 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 USI Electric Smoke and Carbon Monoxide 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, this maintenance-free alarm is suitable for houses, apartments and mobile homes in every room.

This 3-in-1 smart alarm utilizes a sealed battery (included) that will never have to be replaced throughout the life of the detector, 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. Thi USI electric combo 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 battery (approximately 10-years from activation).

Perfect for replacing existing USI Alarms, this combination detector 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 3-in-1 combination alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.
