Customer Reviews For The USI Sensing Plus Hallway Smoke and CO Alarm, 10 Year Battery
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.

Product delivered within 3 days. Easy installation with no complications. Product has had no false alarms so far.
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.
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.
Installed easily, hope it works well...don't want it to alarm, but if a threat, hope it does. Test as expected...hopefully good sensing...
I haven't had a chance to install the alarms yet but I am very please with service
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.
Hasn't been needed yet but install went well.
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.
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.
I did a bunch of research and thes alarms fit the bill!
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.
