Easy to install, no false alarms
I ordered this to replace an older wired smoke detector. I turned off the electricity, removed the wiring harness from the old detector by twisting off the wire nuts and installed the harness from the new detectors. There were no false alarms since I installed it.

I ordered 3 of the USI 2-in-1 hardwired smoke and fire alarms online so that I could replace my current smoke alarms that have expired. They arrived on the date they were supposed to and were easy to install and test. I am looking forward to not having to replace any batteries for 10 years. I highly recommend.

Easy replacement
I ordered direct from USI electric. The six pack was packaged neatly and securely. This detector replaced our 12 year old USI product and plugged into the existing harness. It was necessary to change the base plate, which was quick and easy. The 10 year sealed unit is a real plus. All in all, a great product.

So far, so good
Installed 8 of these in my home to replace 10 year old detectors with 9 volt batteries about 6 months ago. Got tired of replacing batteries, plus the cost of 9 volt batteries seem to increase every year. Had one that had a led that would change in its brightness level every few seconds. An email to the company and it was replaced free of charge. Included the return postage for the old one as well. Very good customer service. I would recommend this product and company. Ask me how I feel about them in 10 years.

USI 2-in-1 Hardwired Smoke & Fire
Ordering was easy, very fast shipping. Everything was packaged very professionally. The product seems very good although i only had them up for two weeks. No false alarms yet!

Easy installation to replace expired alarms
I had a house-full of USI alarms that were over 10 years old. I called to ask what options I had to replace them. The very helpful rep listed several, including these sealed systems with 10-year Li batteries. I ordered them nice discount!, they arrived, and I had them in place with no more than an hour of work, mainly to replace the old mounting plates with the new ones these required. Good experience.

MI106S Reliability
I have this product in my house, I damaged the one that came already installed in the house. I replaced with this exct model because of their functionality and sensibility to smoke.

Highly recommend Universal Security Store.
It was a pleasure doing business with this company, especially the nice lady in the office who helped with a billing question—very polite and helpful. Shipping was fast and product arrived in good shape. At 70 years old, I was on my own with replacing 7 wired alarms. USI instructions are thorough and easy to understand. I also did other reading about dealing with electrical wiring. After turning off the power supply, which was wired separately from the rest of the house, I also used a voltage meter to be sure no power was detectable. Although, it would have been nice to just plug in the existing harness, I used the existing wiring nuts with the connector that came in the box with the USI alarms. I used the third yellow wire for interconnecting the alarms. I pulled the tag to activate the 10-year battery and each alarm sounded as expected to ensure activation. After I put the seventh alarm in the backplate, I turned on the power and all lights were green. I tested each alarm and all worked and I could hear that they were properly interconnected. One try and done! It is important to know that if the backplate screws are too tight, the alarm will not fit under the tabs for hanging it.

Exactly what I needed
I went to Lowes, Home Depot, and Walmart looking for a fire alarm that I could replace with my old one. None of the 4 I bought had the correct adaptor. The first one I got from USI was perfect. Will be replacing another very soon
