Easy to install

I was pleased that I did not have to drill new holes in the ceiling because the new unit uses the same spacing. Perhaps this is a standard, but convenient nonetheless. The instructions were clear enough.

The safety of both smoke and CO detection

My basement stairs hallway smoke alarm was nearing its end of life. I decided to replace it with this combo smoke and CO alarm as an extra bit of protection. It also meets the latest UL217 8th edition smoke sensing requirements which makes me feel a little safer. Very easy to install. With its 10 year battery I'm all set now for the next decade.

excellent product and ordering process

The on-line store was easy to negotiate, the shipping was fast and product arrived intact. The bracket was easy to install and the alarm seems to be functioning well.

Sensing Plus in 2022

After thorough review of brands and features I chose Sensing Plus because it has the most current 2022 industry standards for smoke and carbon monoxide alarms. They were easy to install in the same location as the old ones that were other brands. I ordered directly from USI Store to ensure they weren't expired or had been sitting in inclement weather.

Smoke, Fire & Carbon Monoxide Monitor

I have purchased products from Universal Security Instruments before. They have always been prompt and accurate in delivering my orders. I feel confident in the quality of their products and feel we have added an additional layer of safety to our home.

Rare 3 in one CO2, smoke, fire

Was hard to find smoke, fire, and CO2 alarm. A well know consumer guide rating led me here after shopping for smart alarms. Also upgraded to the latest UL standard.

Top-notch Product

I did a bunch of research and thes alarms fit the bill!

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 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.
