Customer Reviews For The Hardwired Combo Smoke and Carbon Monoxide Alarm
Overall Rating
Product Reviews
These Units are quite easy to install in place of older non-Universal units.
I have tried everything, every brand (except Universal) since I've lived in my house, now over 40 years, and have had nothing but false alarms and irritating resets...usually at something like 3 a.m. So far, nothing but peace and quiet from these. I like the promise of new technology, especially because the "old" technology wasn't very satisfying. Came nicely packaged. Two minor complaints: 1) They should come with at least the larger headed screws for base installation, because I had to scrounge up some from my workshop that had heads large enough to hold the base to the ceiling boxes; and 2) Although the hard wire connectors are supposed to be universal (and they well might be), I found the fit to be just a little too tight, so I had to take a couple of minutes to splice in the ones that came with the Universals. Quality appears to be high...and thank God I don't have to listen to some nagging voice calling out "Fire!" every couple of seconds.
I needed a whole house replacement for new construction detectors that were at end of life and got a good deal on upgraded 10 year battery models and got a few more carbon monoxide detectors to cover every bedroom and added a natural gas detector. Replacing the ceiling mount bracket and a couple wiring pig tails was not too hard. Very happy to not have to replace batteries and to have the best protection for my family.
It was very easy to replace my existing wired smoke detectors with these new USI combo units that detect CO, smoke, and fire. So far I'm very happy with the three USI combo units I installed. After installation, I pressed each units test button and each unit worked perfectly. This was a great investment ordering online from USI. I, also, got a discount for my first online purchase from USI.
Easy to install and works as stated. I will purchase again.
We had a builder installed USI product that needed replacement. We were happy to find this updated version which was easy to install into the existing wiring and plate. Very happy with ordering and shipping process.
Very easy to install, and looks great. With the 10-year battery backup, it's set and go and worry-free! I feel safe and well protected. Highly recommended!
Bought these to replace 14 year old smoke detectors. Easy to connect to existing wiring. Tested and working as expected.
I replaced all the smoke detectors in my house. I had excellent an experience with purchasing USI products and installing them.
I purchased from USI because they were the only ones who made a smoke alarm with both ionization and photoelectric AND a carbon monoxide detector. I put these in each bedroom to make sure my family was protected to the best of ability. I put USI's regular ionization/photoelectric detectors everywhere else. I really like that they are hardwired and will all alert together letting us know about a dangerous condition no matter where we are. I will recommend these detectors to my friends and extended family because they are first rate products and because of the excellent customer service
High quality construction, super easy installation and minimal packaging material.
These appear to be state-of-the-art units. I ordered 3 but one appeared to be malfunctioning. Their customer service is OUTSTANDING and they agreed to replace the one unit immediately. Once I get that unitl installed. Mark me 5-Excellent.
They require us to change the connectors from the wall to the alarm. They were easy to put up and look better than the 10-year-old alarms that were yellowed with age.
Replaced old unit with this model. Easy install and product tested out fine.
I only discovered recently that most smoke alarms do not detect both smoldering and flaming fires. This alarm does both, plus detects CO. The 10 year battery is a huge plus.
Wanted a detector that me upcoming requirements after Kidde recalled my previous detectors and sent me replacements that did not meet the new standard. This product met the new requirements. Was easy to install and has indicator lights that clearly show the status of the detector
Replaced all the smoke detectors in my house in an afternoon. Very easy to install and looking forward to 10 years of zero maintenance.
I purchased 4 dual zone detectors and 3 more including carbon monoxide detection. Shipping was quick and in undamaged clam shell packaging. Install was a breeze and they work perfectly. I was very satisfied so I ordered another set for the tenant on the other side of the duplex I own and live in. Now planning to order another set for another rental I own. 10 years of not worrying about batteries or tenants removing inferior detectors. Definitely recommend.
Easy to install.
Easy to install product. Fair pricing, free shipping and quick delivery. Informative website.
Product FAQs
Yes, if you the alarm has a battery backup. Hardwired smoke alarms are wired directly into your home’s electrical system, but nearly all modern models - including most Universal Security Instruments alarms - also include a backup battery. This built-in battery allows the alarm to continue operating even if your home loses power, ensuring you’re protected at all times.
Power can go out during a fire for several reasons. Intense heat can damage electrical wiring, circuit breakers may trip to prevent further hazards, or flames and smoke may affect electrical panels and utility lines. In some cases, firefighters or utility crews will intentionally shut off power to keep conditions safer. Because of these possibilities, the backup battery is an essential feature - it ensures your smoke alarm will sound even if the fire itself disables your home’s electricity.
For homeowners, this means peace of mind: whether it’s a fire, a storm, or a routine power outage, your hardwired smoke alarm is designed to keep working when you need it most.
Many people assume that every smoke alarm requires a backup battery change, but most Universal Security Instruments hardwired smoke alarms are designed differently. The majority of our models feature a sealed, 10-year lithium free battery that never needs to be replaced. This long-life backup battery is permanently built into the unit, ensuring continuous protection even during a power outage.
Because the battery is sealed, there's no door or compartment for you to open. When the alarm reaches the end of its 10-year service life, the entire smoke alarm should be replaced with a new unit. This design eliminates the need for battery changes, prevents tampering, and ensures you always have reliable backup power.
If you have an older model that uses a replaceable battery, the user manual will provide step-by-step instructions. Typically, this involves twisting the alarm off its mounting bracket, opening the battery compartment, and installing a new battery of the specified type. However, if your alarm is a newer sealed-battery model, you do not need to replace the backup battery at all.
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.
You can replace a single alarm, but for best protection and compatibility it’s recommended that all interconnected alarms in your home are from the same manufacturer and of a similar age.
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.
The AMIC1510SB ("B" version) comes in easy open box packaging. The AMIC1510SC ("C" version) comes in blister card packaging. The only difference between these two models is the packaging.
8th generation smoke alarms, featuring advanced multi-criteria smoke and fire sensors, represent a significant leap in fire protection technology. Complying with UL 217 8th Edition standards, USI 8th edition alarms incorporate the latest innovations to enhance fire detection. USI Sensing Plus technology, a hallmark of 8th generation detectors, offers superior protection against both fast flaming and slow smoldering fires while significantly reducing nuisance alarms.
Yes, all USI Sensing Plus Detectors meet new UL 217 8th Edition requirements for smoke alarms
