CO and Smoke Detector with LCD Display Electrochemical Sensor and 85 Decibel Alarm

It builds up with no way to detect it, most homes have nothing in place to catch carbon monoxide in time. It has no color or smell so nothing warns you it's there. Get CO and smoke alerts whether you're home, at work, traveling, or in a dorm.

A continuous CO sensor samples the air and logs current levels to the LCD. Hit a threshold and the LED turns on, the screen updates, and the alarm fires. A smoke sensor runs alongside so both event types trigger the same combined system.

Three AA batteries let you place it anywhere without needing a nearby outlet. Up to 36 months per set means you drop batteries in and forget about them. Included screws go into any wall or ceiling surface in just a few minutes.

This LCD actively shows system status including any errors the moment they appear. Past high CO readings stay logged so you can check the alert history anytime, and pressing the self-test button confirms the alarm and sensor work on demand.

  • ELECTROCHEMICAL CO SENSOR: Continuously samples the air and logs current CO levels directly to the LCD in real time.

  • 85 DECIBEL ALARM: Fires the moment a threshold is crossed and cuts through any background noise in the room.

  • LCD CO DISPLAY: Shows live carbon monoxide readings, system status, and error flags all on one clear screen.

  • FLASHING LED ALERT: Red LED switches on alongside the alarm so the visual signal backs up the audio every time.

  • SMOKE DETECTION FUNCTION: Runs a parallel smoke sensor so both CO and smoke events activate the full combined alert.

  • 36 MONTH BATTERY LIFE: Up to three years on one set of three AA batteries before any replacement is needed.

  • SELF TEST BUTTON: Press it on demand to confirm the alarm, sensor, and display all respond the way they should.

  • HIGH CO MEMORY: Logs a history of past dangerous CO readings you can pull up and review at any point.

Frequently Asked Questions

Does it need to be wired into the wall to work?
No, the unit runs entirely on three AA batteries so you can mount it on any wall or ceiling surface without needing an outlet nearby or any hardwiring during installation.

How do I know the detector is still functioning between alert events?
The LCD continuously shows system status and flags any errors the moment they appear, and the self-test button lets you confirm on demand that the alarm, sensor, and display all respond correctly.

Does it only detect carbon monoxide or does it cover smoke as well?
It covers both, a parallel smoke sensor runs alongside the CO sensor so either hazard type triggers the full combined alert including the 85 decibel alarm, flashing red LED, and LCD screen update simultaneously.

How long do the batteries last and are they included in the pack?
One set of three AA batteries powers the unit for up to 36 months before needing replacement, though the batteries are not included so you will need to have them ready before the first use.

Didn't have to follow up

Got the confirmation right away, then another email when it shipped. Tracking worked and the package arrived when they said it would. Pretty straightforward

Better price than other places

Shopped around a little before ordering and this was quite a bit cheaper. Delivery went as expected too, so I'm happy with it.

Actually answered my question

I emailed before ordering because I couldn't figure out which option I needed. Got a real explanation of the differences, not just a link to the page I'd already read. Sounds like a small thing, but it helped me decide. Ordered that evening and I'm happy with what showed up.

Good experience again

My first order was just something small a few months ago. That went well, so I checked here when I needed something else. A completely different kind of purchase this time, but ordering was just as easy. Saved me another evening of shopping around!

Picked the wrong option

Totally my mistake, I chose the wrong option and didn't notice until I got the confirmation. Sent an email and they were able to change it before it shipped. Glad I didn't have to deal with sending it back afterward!

Wasn't sure at first

Hadn't heard of Embermont before and wasn't sure about ordering from somewhere new. Just bought one thing to start. It took a little while to ship, but they kept me updated and everything arrived as described. Happy with the purchase and I'd feel comfortable ordering again.

Helpful when there was a problem

There was a mix-up with my order, so I reached out. Sent a photo and they explained what would happen next. Didn't have to tell the same story to a bunch of different people, which I appreciated. All taken care of now

Found it online instead

They didn't have the one I wanted when I stopped by the store, but suggested checking online. Was able to order it on the website later that day. Would've preferred to take it home right then, but this worked out fine.

Return was straightforward

The order arrived fine, but I decided not to keep it. Emailed about a return and got clear instructions. I was mostly worried about having to follow up on the refund, but got a confirmation once the return was processed and the money came back afterward. Didn't have to chase it down.

Exchange taken care of

Needed to exchange my order for a different option and figured it would be a hassle. It didn't happen overnight, but the team explained what to do and kept me updated. The replacement is here now and it's the right one this time. Thanks for helping me sort it out.

Thanks, Michael!

Michael, the owner, was patient with all my questions when I stopped by the store. I hadn't quite decided what I wanted and didn't feel pushed to buy anything. Went home, thought it over and ordered online later.

Helpful even after the purchase

Had a question after my order arrived and wasn't sure how much help I'd get once the sale was done. They got back to me with a clear answer and that took care of it. Happy with the purchase, but the help afterward stood out.
