Experience the next level of fire safety with the Kidde Hardwired Smoke & Carbon Monoxide Detector, 10-Year Battery Backup, Voice Alerts, Interconnectable LED Warning Light Indicators, 4 Pack, model 30CUA10-V. 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. Voice alerts clearly announce “Fire!” or “Warning Carbon Monoxide!” to help identify which hazard is detected. 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. Meets requirements of 9th Edition UL 217, UL 2034 4th Edition, FCC, and CSFM.
2-IN-1 DETECTION: Alerts you to both smoke & carbon monoxide (CO) using a single, cost-effective device.
HARDWIRED & 10-YEAR BATTERY BACKUP: Operates on 120V AC wiring (installed in the ceiling). No battery changes for 10 years & saves up to $40 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, & FCC standards.
VOICE ALERTS: Crystal-clear voice alerts will say “Fire!” when smoke is detected or “Warning! Carbon Monoxide!” if CO is detected, so you can react quickly.
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.
3 LED NOTIFICATIONS: LED lights indicate alarm status, green = normal operation, amber = operating error, red = smoke or carbon monoxide detected & a loud 85-decibel alarm will sound.
10-YEAR WARRANTY: Begins when alarm is powered on. If that date is unknown, it should be assumed that alarms should be replaced. (10-yr limited warranty on alarm, not a battery performance claim.)

Best Smoke and Carbon Monoxide Detector
I installed 5 of these in my home to replace the old battery smoke detectors and they work great. They come with are different connector, so you have to. get an electrician or turn of the fuse if you have the skills to replace the electrical pigtail (wires) yourself. I would have done it myself but my wife wont let me climb a ladder anymore. Fast install and they work great, connected to my current security system and with a 10 year battery, I will no longer have to get up a 2 AM and try to find and replace the stupid battery. I just ordered 5 more to completely replace all of the old smoke detectors and add a new one to the garage where I charge my car at night. Great product. A little expensive, but you are getting carbon monoxide detection where I only had smoke detectors before and worth every penny, knowing I will not have to deal with them for 10 years.

Hardwired kiddie smoke /co2 alarm
The installation is easy. I had to install 2 of these on 17 ft high wall and ceiling. I have 18 ft little Giant ladder fully extended. I had to work with 2 hands, not holding ladder was bit scary. I had to turn my body 90 degree to wiring the alarm. The product looks smaller than predecessor FireX alarm. I tested it by pushing hush button, it is working ok. The sounds are so loud, all 5 alarms went off same time. Interconnected feature is working fine. It has latest certification. It comes with 10 year built in lithium ion battery backup. I hope everything works well for next 10 years.

Easy Upgrade from FireX – Reliable and Simple to Install
These detectors work great, and I would highly recommend them! I replaced my old FireX alarms with these, and the swap was simple—I didn’t even need to install a new mounting bracket. (Since FireX was bought out by Kidde, the compatibility made this upgrade even easier.) The wiring was pretty straightforward as well, although I did have to cut back a bit of the wire cover so I could wrap the new wire to my house wire securely with the wire nut.They are a little bigger than my older FireX models, but that doesn’t bother me. I can’t speak to the 10-year battery life yet, as I’ve only had them installed for about a week, but so far everything has been working perfectly.The built-in battery backup and voice alerts give me extra peace of mind, and I really like that they’re interconnectable for whole-home safety. The LED indicators are also a nice touch for clear status checks at a glance.Overall, excellent quality and an easy upgrade from older alarms. If you’re looking for reliable protection with simple installation, these are a great choice.

Easy installation
Our house’s smoke detectors began to fail at almost exactly the 10 year mark. One by one, they would chirp and it would freak out the dog. We decided to replace all 8 detectors with the same Kidde brand, hoping it would be a simple plug and play replacement. The existing plugs were not compatible with the new devices so my husband had to re-wire all of them.

Good price and easy to install.

Kiddie has a new style of elecrical plug and mounting ring.
Good product and easy to install. I had to replace 6 detectors in my 10 year old house. It would have been easier if the mounting brackets and electrical plugs would have been the same as the previous model, but that was probably a ten minute per detector delay. The product did arrive quickly and the manufacture date was within 1 month of the date that I received them!

It didn’t go 24 hours before false alarming
One of the four installed units false alarmed immediately the night after installation. One set of beeps and silent. Obviously real smoke would not be gone in 5 seconds. I switched from Nest gen2s, which had a smoke chamber enclosed with very fine mesh to avoid bugs pieces of lint to enter the chamber. This one has nothing of that sort which was a huge disappointment, as I figured that’s industry best practice at this point. My Nest gen2s had perfect reliability record. My older Nest gen1 had no mesh either, which caused false alarm issue in the past due to spider getting in the chamber. Not sure if that was the cause of this specific false alarm but it’s a sign for things to come for sure. An unreliable alarm is worse than no alarm.
