Product description
【Upgraded Dual Sensors to Ensure Your Safety】: Compared with most carbon monoxide smoke detectors on the market, our detector sensors have a lifespan of up to 10 years, while other detectors on the market only use three-years life sensors, so our products have a longer service life. The combined smoke and carbon monoxide detector uses a photoelectric smoke sensor and an electrochemical sensor to detect smoke and carbon monoxide faster and more accurately, protecting your home from two potentially deadly threats.
【WirelessI Interlinked Alarms&Easy to Use】: All Alarms wirelessly interlink with each other. The products are pre-configured and can be used directly. The instructions also provide detailed steps to help you easily set up the product. When the product detects gas, all alarms will sound off together. This ensures all areas of your home are protected and all occupants are notified during an emergency. Our interconnected alarm system creates a ‘Mesh’ style network where each alarm is connected to all other alarms. This Mesh network provides more stable and reliable wireless performance and a greater coverage range of up to 250m(820 ft) compared to other detectors.
【Battery-Operated&Easy Installation】:This CO alarm is powered by large capacity 3×1.5V AA batteries (included), and this combination smoke and carbon monoxide detector can be easily installed using the included mounting bracket, screws, and anchors. The detector’s battery life is up to five years, and we also provide a lifetime free battery and product replacement service to save you money.
【LCD Digital Displays & Multi-directional Sensing Hole】: The informative LCD will show you the battery level and real-time CO levels in PPM (parts per million). If there is fire and carbon monoxide with a concentration over 0.1% db/m, the blue light flashes rapidly. If CO is detected, the red light will flash. Dense gas-sensing holes can prevent alarms from causing false alarms and reduce your worries.
【Safety Guarantee and High Quality】: This product has passed the UL standard report issued by the laboratory accredited by ILAC ISO 17025/NRTL standard. We have complete certificates of UL217 and UL2034 testing. Protect yourself and your family from the silent danger of carbon monoxide with our top-of-the-line Carbon Monoxide Detectors. With its advanced detection capabilities, our Carbon Monoxide Detectors offer you an added layer of security and peace of mind. If you have any questions about Kesymo smoke and carbon monoxide detectors, please feel free to contact the Kesymo team, we will provide you with a Lifetime free after-sales service.

Great performance and pretty accurate.
Excellent interlinked base Smoke Carbon Monoxide Detectors. I bought these 6 packs as I had to use it in several places of our office and found it pretty reliable so far. We have tested these detectors with real smoke to see its functionality and it work fine. The great think is these are interconnected so in a sense it works like a kind of professional interconnected smoke detection system. We can’t wait to install it in our office. These comes with 4 batteries so you dont have to worry about purchasing and spending extra money for it. Its very easy to install and dont need any operating skills to connect it together. The display on each device looks very professional. I liked the built quality of the products.Only thing i didnt like as it comes with partially broken box due to poor delivery handling system of Amazon. Hope amazon will look onto this issue.

Easy to install with clear display
I installed this smoke and carbon monoxide detector about two months ago in my hallway. The unit arrived in a box with the detector, mounting bracket, screws, and anchors included. Installation took about 10 minutes – just screwed the bracket into the ceiling and twisted the detector onto it. No wiring needed since it has a built-in 10-year battery. The LCD screen displays carbon monoxide levels in PPM and shows battery status. The display is easy to read from floor level. The LED indicators flash different colors – red and blue – depending on what’s detected. The test button on the front lets me check that it’s functioning. When pressed, it emits an 85dB alarm which is quite loud. The test button also silences false alarms when pressed again. The detector has sensing holes around all sides for airflow from multiple directions. After two months mounted on the ceiling it’s been functioning consistently. The display remains clear and the battery indicator shows full charge. Overall a straightforward detector with convenient features and simple installation.

Smoke and carbon monoxide detector combo!
This dual smoke and carbon monoxide detector is a dependable and well-designed safety device for any home. The combination of a photoelectric smoke sensor and an electrochemical CO sensor provides quick and accurate detection, offering peace of mind knowing it protects against two major hazards in one unit. I especially appreciate the long-lasting 10-year sensor and battery life, which eliminates the need for constant maintenance or battery replacements.The LCD display is clear and easy to read, showing real-time CO levels and battery status. The LED indicators are helpful as well—red for carbon monoxide and blue for smoke—so it’s easy to tell what’s happening at a glance. The 360° airflow design ensures it detects threats from all directions while reducing false alarms.Installation was straightforward with the included mounting hardware, and the one-touch test button makes checking the system simple. The 85dB alarm is loud enough to wake you if danger strikes, and the ability to silence a false alarm with a quick press is convenient.Overall, this detector delivers reliable, long-term protection with thoughtful features that make home safety effortless and worry-free.

Very well made, all 3 link together, great price
So far this aet of 3 appear to be pretty good smoke heat carbon dioxide detectors although is a little confusing to get them linked up, so if one goes off they all go off…. I have one in my shop building next to my house & one upstairs & one downstairs in my home and they all 3 communicate well. The shop is 20ft from house and it appears to communicate with the other 2 in the house just fine. Not looking forward to changing batteries in 2 years and going through the whole process of getting them all linked up again. Be sure to save your instructions or you’ll never remember how to do it again in 2 years. These 3 were a lot cheaper than buying just 1 NEST replacement that just expired.

Easy installation process
So far so good. The battery power makes installation fast since you don’t need any wiring. Perfect for anyone who wants reliable protection without complicated setup. They connect to each other. Will update when we have it for a couple of more months.

Don’t make this same mistake 🙃
These smoke & co alarms work very well. They are super loud, they look much nicer then the old bulky styles of alarms. I was able to test with smoke and they did great.Unfortunately upon ordering I made a mistake not realizing this set did not interconnect together. Between Amazon customer service & myself we could not figure anything out. Thankfully the company is very easy to get ahold of through their after sales email which is listed in the instruction manual when you recieve the alarms. They have chosen to go above & beyond to help me and send me a new set of alarms that are able to be connected together. Huge thank you to the company for helping so much!*I didnt notice on the listing but there is a difference between the white & silver alarms. Silver doesn’t connect together, white does.

Just a regular fire alarm. Not special
Battery lasted about 3 months once plugged in. Fun fact! WHEN the batteries die, it beeps every 20 seconds until you change them. This is an amazing feature at 2am when your alarm that is 15ft up decides to let you know its dying.Another issue is that the base of it is not the same as the standard fire alarm bases so you have to rig it to fit. It is a rough replacement if your house was built with standard alarms.I can confirm they will communicate well with each other and once one goes off (like when you are installing 8 and have to do a test with each install,) the rest will go off for about a minute.These do not have a ten year warranty. Nor do they last 10 years. They are just regular fire alarms that take a different battery (AA), and MIGHT last up to 10 years between changes. Read the fine print.
