Experience the next level of fire safety with the Kidde Hardwired Smoke & Carbon Monoxide Detector, 10-Year Battery Backup, Interconnectable LED Warning Light Indicators, model 30CUA10. This smoke & CO detector has enhanced sensing technology that reduces false alarms often caused by cooking and sends fast alerts that help give your family more time to get out safely. To detect carbon monoxide, an electrochemical sensor is used. This alarm offers a modern 5-inch design ideal for all living spaces such as living rooms, hallways, kitchens, & bedrooms. Comprehensively tested and designed to the latest UL standard for safety and reliability, the 5-inch smoke & CO alarm is powered by 120V AC wiring with a 10-year built-in lithium battery, so you never have to change a battery for the life of the detector (not a battery performance claim). In addition, it’s self-testing and easy to install with the included twist-and-click mounting bracket. This Kidde combination alarm is equipped with end-of-life notifications that will beep to remind you it’s time to replace it at the of its 10-year lifespan. Meets requirements of 9th Edition UL 217, UL 2034 4th Edition, FCC, and CSFM.
2-IN-1 DETECTION: Alerts you to both smoke and carbon monoxide (CO) using a single detector.
HARDWIRED and 10-YEAR BATTERY BACKUP: Operates on 120V AC wiring (installed in the ceiling). No battery changes for 10 years and saves up to 40 Dollar over the life of the detector.
ENHANCED SENSING TECHNOLOGY: Reduces false smoke alarms often caused by cooking. Comprehensively tested to meet the latest UL standards, meets UL 217 9th Edition, UL 2034 4th Edition, and FCC standards.
INTERCONNECT CAPABILITY: When one alarm sounds, they all sound, so you can get out faster. (Different models offer different interconnection options and requirements. See User Guide for more info.)
SELF-TESTING ALARM: Internal components ensure alarm is always operating as expected. Not a substitute for a manual push test, perform a button test once per week to verify alarm operation.

Kidde Hardwired Smoke & Carbon Monoxide Detector
Installed the Kidde hardwired smoke + CO alarm and it works exactly like it should. The 10-year backup battery is a huge plus, and the interconnect feature gives peace of mind since all the alarms go off together. The LED lights make it easy to tell whether it’s smoke or carbon monoxide. Setup was quick — just swapped the wiring harness and mounted it. A little bulkier than some models, but totally worth it for the reliability. I bought 4 of these and all of them are working as expected.

Straightforward Replacement, but Consider Using a Battery Type Instead.
Replaced our old garage alarm with this since the AC wiring was already there. You would think that an advantage to hardwire is that you don’t have the damned thing screaming at you in the middle of the night to replace the battery, but this has a backup battery, so guess what? It’s going to fail overnight! You might consider getting the Lithium battery type because the battery and sensor age out at about 10 years, so you might as well replace the whole thing, UNLESS you need to connect this to an alarm system. I tested ours with a candle wick because some smoke detectors, believe it or not, arrive incapable of detecting smoke. Go figure.

Easy to install. Is a combo Smoke and CO2 detector.
Easy to install, though it was different from the one we were replacing. Came with something to leave over the detector if construction was still going on. In our case, we were replacing one that went through construction without protection from dust.Works with our other Kidde hardwired detectors. Love the 10-year battery, which may outlive us. There were cheaper ones, but my other ones were Kidde so I knew this one was compatible with them. It plugged right into connection plug, though as I stated above, we did have to change out the bracket even though the previous one was just 4 years old.I think our previous one was just Carbon Monoxide so having a dual detector was an improvement and am very happy with this product.This one looks smaller than our previous one, but is not. Might be a slicker look, more up to date.I would suggest this item to friends and family.

Necessary for every home, and reliable!
Great product at great price! Re-detectored the whole house 4 months ago, haven’t had a single issue with any of the 6 I bought.

Great detector but must replace the ceiling mounting plate
Great smoke & CO detector. Even though it is the hard-wired version, it is easy to insert the soldered leads into the plug of the old detectors so they don’t have to be rewired. I found that I did have to use the ceiling hanger that came with the detector as the new detector could not be secured to the ceiling properly. That just meant that I needed to replace the ceiling mount plate at the same time as the detector before installing the new one. Otherwise, the installation was fairly simple and the detector seems to work as intended.

Didn’t even last 9 months
I purchased three Kidde hardwired Smoke/CO alarms with internal 10 year battery, on March 19, 2025 so that all units in my home would match. One of them has already become defective.For the last week, it has been giving 3 loud beeps every 2 minutes for hours at a time—even after resetting. It works for a day, then starts all over again. This has been happening at all hours, including 4 AM, and has been extremely disruptive for my family and pets.I’ve had to disconnect the faulty unit and place it in the garage because it would not stop beeping.When I go to order a replacement, I see that the model is no longer available and has already been replaced with a new version. Since I purchased a matching set of three, I need a solution that allows me to keep my alarms consistent.Please let me know the next steps for a warranty replacement or equivalent model.

Excellent Product
Excellent product, easy to install but get the adapter so you don’t have to bother with wiring it in. No batteries needed, it has a built in battery that lasts for 10 years.
