Kidde Smoke Detector & Carbon Monoxide Detector Combo with 10-Year Battery,‎White

Works
This item is sleek and nicely fits into a room’s decor.When installed, I expected to see a green light after testing, but it kept showing a red light. I called the company and found out that this smoke alarm/carbon monoxide detector would only show red. So as long as it goes through the testing stage, after installation, you are good to go.BTW, reaching out to the company was a breeze. I was able to talk to a real person right away.

This thing saved my family’s lives
I bought this a few years ago because I needed a smoke detector, but I also wanted CO detection. I always wondered if it actually worked, as I am prone to do with things that only do something in an emergency. I got my answer in the wee hours of yesterday morning: Our power was out for almost a week, in a dangerous heat wave. We have a generator to run essentials like fridges and freezers, and we also plugged in a small window unit AC because it was that dangerously hot. At one point we moved the generator to what we thought was a better location, neglecting one vital detail: just above that spot was an attic vent.Everyone was asleep, and around 4am my brother and I were awoken by a very loud BEEP BEEP BEEP BEEP we had never heard before. Once we figured out it was my Kidde detector, we were confused. The generator had been running all week, and we’ve never had a CO alarm go off before. No one has symptoms. We had another CO detector, and it wasn’t going off. Was the Kidde one defective? We took it outside, it stopped beeping. Back in the house: BEEP BEEP BEEP BEEP. Oh, it’s not defective. Called 911, shooed the rest of the family out of the house. Firemen arrive, and they praise our quick response: Inside the house the CO level had risen to 40 ppm, a dangerous level over time, but the attic was a whopping 200 ppm. We could have died if we had ignored the alarm. As it was they urged all of us to go to the emergency room. You know how in the US you can tell how bad off you are by how fast the ER starts treating you? They had all five of us on oxygen within minutes of walking in the door. Let me reiterate: none of us had symptoms of CO poisioning, not even our chronically ill members, but we all had elevated blood levels.The other detector we had DID go off, but not until it had been placed in a room with a window near where the generator was. Needless to say, I’ve already ordered another Kidde unit and will probably acquire more in the future.

Good Product
Mounted and using in our kitchensatisfied

Lasted less than a year
I only had this smoke/carbon monoxide alarm for 10 months before it started malfunctioning! It started going off randomly in the middle of a work call (I’m remote) and I had to end a meeting early. It was the smoke beep (3 long) not carbon monoxide (4 long) and by the time I got on a step stool to get it, it had stopped. I checked around and obviously there was no smoke, no fire, I even checked outside because the window on the other side of the room was open, but NOTHING. Then as I was ready to call my boss back there it went again. NO REASON! There’s also no way of opening it, or removing the batteries and the hush only works for a couple of minutes. I took it down from the ceiling and waited for it to go off again. Of course it didn’t, not until 4 days later, again no smoke, no one even cooking, nothing! What an absolute piece of GARBAGE!

As expected.

Simply install the back plate on a wall (high enough) or the ceiling with the supplied screws.Remove the plastic cover from the detector; it will beep once, loudly. Watch your ears.There is nothing else you need to do for the next 10 years!
