Customer Reviews For The Hardwired Combo Smoke and Carbon Monoxide Alarm with 10 Year Battery Backup
Worked well for 7 years and had to replace all now
Replaced original home's AC powered smoke alarms. Easy to wire and mount. Like the triple sensor and 10 Year backup battery.
Second one of this model. Love the new intelligence and built in 10 year battery.
Ordered and received well on time. Very easy to instal and also fit on existing ceiling bracket.
Replaced five 8 year old smoke detector with this new model. Very simple and took about 10 minutes as they had the same connections as the old ones.
Have had in place for a full year now, definitely an improvement over the Kidde detector located outside our basement bathroom that would detect steam falsely as smoke. Yellow interconnect wire goes to house red wire ... just remember white to white and black to black and yellow to whatever is left. Love the idea of never replacing the battery, hope that holds true.
This new model had a different base plate from my old model but it was easy to replace. I love the fact I wont have bird tweets when the 9 volt battery runs out which it constantly did. Quick service and good technical tips from Nickole
We have had our new USI combo hard wired alarms installed for over a month now and we couldn't be happier! After YEARS of false alarms from our First Alert combo alarms, most often in the middle of the night with no perceptible triggers, we had grown weary and anxious. We decided to install new alarms and researched and found USI discussed in Consumer Reports. These alarms work well but have not been constantly triggered by shower steam from the bath or smells/smoke from cooking or a spider crawling on the lens. I'm finally able to go to sleep at night without anxiety that a false alarm will wake the whole house. The alarms DO work - when I really scorched something while cooking the alarm did go off - and was much easier to silence than our old ones. I'm glad I will not have to remember to replace the batteries every six months. My electrician asked me to let him know if they are good so he can recommend them to other clients so that's my next step. Meantime I can recommend them to anyone reading this review - they were money very well spent! I read that something like 70% of house fires involve disconnected fire alarms because people get tired of false alerts - save your family from potential tragedy by invested a few extra dollars not really, when you count the savings from a permanent battery in these excellent USI combo alarms.
It's working great so far.
Excellent product. Easy to install. Great customer service. One alarm didn't work because the activation tab was somewhat pulled out. I called the company and a new one was immediately shipped to me.
Just what I order to replace old detector and it fit same location
Very easy install and I've had my last one 10 years. Love this item
I like the new USI dual Sensing Plus alarms. They can detect more types of fires and smoldering fires. They meet the New UL 217 8th Ed. Requirements which is great for resale. Hardwiring is easy with included pig tail for hardwiring. I needed several combination sensors with CO.
Love your products.
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.
I only had one combination alarm. The other 5 were smoke detectors. But this one installed as easily as the other alarms, and they have been in a week so far without any problems. I'm happy to have the added protection this combination detector provides. It had been recommended by my local fire department to replace my old alarms with smoldering fire and open flame alarms.
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.
The USI AMIC1510SB 3-in-1 Sensing Plus® Hardwired 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.

The ideal addition for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes in every room. This 3-in-1 alarm includes a 10 year lithium free battery backup that will never have to be replaced throughout the life of the detector, 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 USI Electric Smoke and Carbon Monoxide Detector features microprocessor intelligence that assists in completely eliminating nuisance alarms, 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).
Perfect for replacing existing USI Electric Combination Detectors, this combination alarm features a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick activation battery pull tab makes it easy to install while the deactivation key switches the combo alarm off and makes the batteries safe for disposal. Once the 3-in-1 combination alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.
