Coreel CO Smoke Alarm Detector
The combination smoke and CO detector detects both smoke and carbon monoxide faster and more accurately using a photoelectric smoke sensor and an electrochemical CO sensor, protecting your home from two potentially deadly threats.
- High-accurate electrochemical sensor(the most accurate CO sensor)
- Infrared photoelectric sensor(the best sensor to detect smoke while minimizing false alarms)
- LCD concentration PPM
Combo Smoke and Co Detector is Easy to Install
Battery Operated for Convenience
3*1.5V AA dry battery (package not included)
After installing 3 batteries, you can hear the sound of "di", and it starts working normally after 2 minutes. In operation, it displays nothing with a power-saving design. Ultra-long standby time, low current consumption.
- Press the button “test”, and the smoke and carbon monoxide detector alarms ≧85db, loud enough to alarm you of the dangers no matter whether you’re asleep in the bedroom or watching TV downstairs.
- So easy to install wherever you stay for long periods: drill the two marked installation holes. Tap the two plastic grommets into holes with a hammer. Mount the bracket to the ceiling by inserting and tightening the supplied screws into plastic grommets.
TIPS: Please install the sirens at 0.3~1m below the ceiling because the concentration of carbon monoxide and smoke is smaller than that of air.
Sound & Flash Alarm & LED indicating Alarm
- Green LED indicates normal operation
- Red LED Indicates Smoke Alarm
- Blue LED Indicates Carbon Monoxide Alarm
Test/Silence Button
With a convenient test/silence button, you can manually test the alarm to ensure everything is functioning properly or temporarily eliminate annoying false alarms.
LCD concentration PPM
The LCD can indicate real-time carbon monoxide concentration. (For power-saving, it cannot stay showing ppm every second. It only lights up when you press the test button.)
Battery Powered for Convenience
The CO smoke alarm is powered by 3 x 1.5V AA batteries(package not included) for ease of use.
"Lb" means low battery, and please replace the batteries ASAP.

Love these detectors! User friendly as well as compact and attractive. My only problem is I couldn't get the back panel on. I'm a debit citizen lady who needed help. Other than that, I love it and I highly recommend it.

I recently moved to a new home with old detectors. I decided to replace them all for peace of mind. I wanted smoke and carbon monoxide detectors that would also look "nice" and "modern" since they are visible. These are super easy to install, seem to perform reliably and are much nicer than the bulky ones I’ve had in the past.

I ordered these in February to replace the ones in my house as of writing this one appears to be not working as it's doing nothing but making annoying statics sounds that is driving me crazy. But 2 out of 3 being perfect I guess I can't complain.

This is the best smoke/carbon monoxide alarm I ever had. In the past, I had two separate alarms for these functions. The smaller size fits anywhere and is very unassuming. Great purchase.

Unit was easy to install however after 10 months we had to call the fire dept. to come do an air quality check to confirm we were not going to die. Unit started beeping giving the code "co Err" with a red and blue light. We changed the batteries and still continued beeping. Fire dept. fortunately confirmed we were at zero Co levels throughout our home and the detector was malfunctioning and needed to be replaced. Fire department asked what the date stamp was on the back to make sure it was in not outdated but there was no date stamp, which it should of had. I guess the only good thing other than easy install was the eye candy walking through my house at 7:30pm while I was in my pajamas 😉

The appearance is better than most others. It installs easily. The buttons to pause the alarm are on top so don't place it out of reach.
