Kidde P3010CU Smoke and Carbon Monoxide Alarm, Photoelectric with Voice, 10-Year Battery Overview
The Kidde P3010CU smoke and carbon monoxide alarm is a combination alarm that pairs a photoelectric smoke sensor with an electrochemical carbon monoxide sensor in one unit. It runs on a 10-year sealed lithium battery, so there is no battery to replace and it keeps working during a power outage. It gives clear voice alerts, announcing Fire for smoke and Warning Carbon Monoxide for CO, plus a Replace Alarm end-of-life message, and it sounds an 85-dB horn.
As the Kidde P3010CU, this photoelectric smoke and CO detector is a worry-free, battery-powered unit. As a smoke and CO alarm with voice it tells you which hazard it senses, and as a 10-year sealed battery alarm it needs no battery changes. As a combination smoke carbon monoxide alarm it covers two hazards in one device with a single Test/Hush button.
This is a smoke-and-CO alarm, not an explosive-gas detector, an air quality monitor, or a smart WiFi alarm. Compare it against other combination smoke and CO alarms, dedicated smoke detectors, and carbon monoxide alarms and detectors, and browse the Kidde CO alarms range before ordering.
What This Alarm Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Smoke and CO in one unit | Purpose-built | Photoelectric smoke plus electrochemical CO sensing. |
| Smoldering-fire response | Strong | Photoelectric sensing suits slow, smoky fires. |
| No-maintenance battery | Strong | Sealed 10-year lithium battery; no replacements. |
| Clear spoken warnings | Strong | Voice announces Fire or Carbon Monoxide. |
| Explosive gas / air quality / WiFi | Not suitable | Choose a gas, air-quality, or smart model for those. |
Smoke and CO alarms are life-safety devices, so respond immediately: for a Fire announcement get everyone out and call emergency services, and for a Carbon Monoxide announcement move everyone to fresh air and call for help. This is a residential early-warning alarm; it is not built for occupational settings where carbon monoxide can reach IDLH concentrations that demand industrial gas-detection instruments and rescue procedures, so use the right tool for each environment. Because it uses photoelectric smoke sensing, it responds well to smoldering fires but is not an ionization or dual-sensor alarm, so consider your fire risks; install and place it per the Kidde manual and local codes on each level and near sleeping areas, and replace the whole unit when it announces Replace Alarm at end of life. Learn placement and CO risks in our CO detector placement guide and carbon monoxide exposure symptoms guide.

Frequently Asked Questions
Does the P3010CU detect both smoke and carbon monoxide?
Yes. It is a combination alarm with a photoelectric smoke sensor and an electrochemical carbon monoxide sensor, so one unit covers both hazards. Voice alerts tell you which one it is: Fire for smoke and Warning Carbon Monoxide for CO.
What kind of smoke sensor does it use?
It uses a photoelectric smoke sensor, which responds well to smoldering, smoky fires. It is not an ionization or dual-sensor alarm; if you want the fastest response to fast-flaming fires too, add an alarm with ionization or dual-sensor coverage.
How is it powered?
It runs on a 10-year sealed lithium battery, so there is no battery to change and it keeps working in a power outage. It is battery-powered, not plug-in or hardwired, which makes installation simple anywhere you need coverage.
What do the voice alerts say?
The alarm announces Fire for a smoke or fire event and Warning Carbon Monoxide for a CO event, so you know which hazard to respond to. It also announces Replace Alarm when the unit reaches the end of its life.
How long does the alarm last?
It is designed for about 10 years, matching the sealed battery, and carries a 10-year limited warranty on the unit. When it reaches end of life it announces Replace Alarm, and you replace the whole unit.
What is the Test/Hush button for?
A single Test/Hush button lets you test the alarm circuitry and temporarily silence a nuisance alarm, such as light cooking smoke. The LED indicator flashes to show alarm, standby, or error status.
How loud is it?
It sounds a loud 85-decibel alarm along with the voice announcements, which is designed to be heard through a home. The combination of a horn and spoken warning helps people react quickly and correctly.
Where should I install it?
Follow the Kidde manual and local codes. Smoke and CO alarms are generally installed on every level and near sleeping areas; a combination unit covers both, but confirm the recommended locations and mounting for your home.
Does it detect explosive gas or monitor air quality?
No. It detects smoke and carbon monoxide only. It does not detect natural gas or propane and does not monitor air quality like temperature, humidity, or TVOC. Choose a different Kidde model if you need those functions.
Is it a smart or WiFi alarm?
No. It is a standalone alarm with a local horn, voice alerts, and an LED; it does not connect to WiFi or a phone app. If you want app notifications, choose a smart alarm instead.
What should I do when it alarms?
For Fire, get everyone out and call emergency services. For Carbon Monoxide, move everyone to fresh air, call for help, and have the CO source found and fixed by a professional. Do not re-enter until it is safe.
Can I use it in a kitchen?
Photoelectric alarms are generally less prone to cooking nuisance alarms than ionization, and the Hush feature helps, but follow placement guidance to keep it a safe distance from cooking appliances to reduce false alarms.

Easy to Install & Peace of Mind
Very easy to install and set up. I like having both smoke and carbon monoxide detection in one unit, and the 10-year battery provides peace of mind without having to worry about frequent battery changes. Great quality and an important safety addition for any home. Highly recommend!

Reliable Detector with Helpful Voice Alerts
Installed this in our home and really like it so far. The 10-year battery is a big plus because I don’t have to think about replacing batteries, and the voice alert is actually helpful since it tells you what the problem is instead of just blasting a loud alarm. Installation was easy, it feels well made, and overall it gives us extra peace of mind. Happy with the purchase.

setup is easy
I installed this in the old nest unit I had and it went right in. What I like is the 10 year battery. Easy setup and test check.

Check the date!
This is a 10 year battery alarm. That's great ( and accurate based on past experience). However, the product says to count from the date on the back of the unit. I received mine 6/2026 but the date on back is 4/2024. So we are starting with only 8 years.

Quality and Price
This is the best on the market, lasting 10 years, and it really does, this is the 2nd after replacing the end of the 10 or mark. I am pleased with the product, all others fail in comparison to Kidde Smoke & Carbon Monoxide Detection.

Total Trash. Buy your alarms at Home Depot if you want customer service and don't buy Kidde.
I would like to add to my review that a manager of Kidde was kind to send me replacement alarms.Unfortunately I do not expect these to last more than a year either. Since my original review the last 2 alarms I had originally installed have also malfunctioned.I purchased 5 of these 13 months ago. I thought I will pay the extra for Lithium battery alarm so I won't have to get up and down a ladder changing batteries. Boy was I mistaken. I'm 70 yrs old so I can't really be going up and down ladders.The five smoke & Carbon Monoxide detectors cost me $262.55 plus $125 to have installed.So far three have malfunctioned in 13 months beeping and yelling fire during the night. I removed them and contacted the Amazon seller who referred me to Kidde who manufactured them which makes sense until I contacted Kidde. There is a 10 yr stamped right on the alarm. Here is what Linda Rush from Kidde customer service wrote me" To assist with troubleshooting, what rooms in your home are the units located in? Are the units located near a fan, vent, bathroom or window? How often do you clean the alarms as nuisance alarms particularly in the middle of the night, are caused by something interfering with the sensor. These units are looking for particles of combustion, so when a small insect or piece of dust gets into the sensor, the unit will interpret this as smoke particles."THEY WANT ME TO GET ON A LADDER AND CLEAN INSECT AND DUST PARTICLES OUT OF THE ALARM????No offer of replacement even with the 10yr warranty. Do yourself a favor and buy your alarms at Home Depot. You can return them to Home Depot.

Not a fresh product!
Although the detector has a 10 year battery, the "date code" on the package indicated it was manufactured in 2023.Product may fail in 6 to 7 years.
