Customer Reviews For The USI Sensing Plus Smoke, Fire and CO Alarm with 10 Year Battery

Tippy Toe...Lemon Tree!!

Great deal on this reliable alarm, a festivus for the rest of us!

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.

Smoke/Fire/ Carbon Monoxide Alarm

Glad, to locate the updated UL217 , 8th edition detector to bring my home up to code for 2024. Easy installation and Universal Web Site delivered my detectors on time. Will, purchase my products as needed from them.

AMIC3511SB USI Sensing Plus Multi Criteria and AMIC1510SB USI Sensing Plus 3 in 1

Just what I order to replace old smoke detector

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.

Product seems good, will really only know if it detects an issue. I like it senses 3 potential problems

Alarming alarm

Quick shipping. Alarms are a breeze to install. Loud alarm. Hope I never have the need to test them for real.

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.

2 units purchased

Easy install and product tested out fine. Time will tell about durability and battery performance.

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.

Combination Alarm with 10 year sealed battery

I particularly liked the features the AMIC3511SB combination alarm. It came within two days of ordering with all of the hardware I needed for quick installation.

Happy to find a 3 in 1 detector

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