Product Overview

The First Alert SC05CN Combination Smoke Alarm and Carbon Monoxide Detector helps protect you and your family from two deadly threats: fire and carbon monoxide. Fire is a deadly threat to every household; it can strike anywhere, any time. Carbon monoxide (CO) is a leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Symptoms of carbon monoxide poisoning are like the flu, and you might not even know you're in danger at first. This dual smoke and carbon monoxide alarm is an excellent way to protect your family. The SCO5CN uses an electrochemical carbon monoxide sensor, the most accurate technology available. The alarm uses photoelectric smoke sensing technology which reduces nuisance alarms, making it ideal for cooking areas. Photoelectric smoke alarms are great for sensing slow smoldering fires quickly. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The SCO5CN alarm uses different 85-decibel horns and lights depending on whether it's alerting you to smoke or carbon monoxide. A low battery signal alerts you to replace the battery and end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 7-year limited warranty. UL listed.

Easy to install, the holding bracket was a different size than my old one, but I was able to use the same screw holes to get a secure fit. Price was ideal compared to other models.

Unit only lasted a little over 4 years before the end of life started beeping according to the date code that was close to my move in date so I know it didn't sit on the store shelf very long. This is too expensive to get a little over half the life of the unit. Plus I have them in my tenants apartments and expect to only have to replace batteries etc on schedule, not get premature calls. I'm considering trying a Kidde product as I'll be I'm shopping to replace it and others soon. I put hardwired kidde in the finished basement and two first alerts on the first floor for redundancy, plus smokes in every room and quadrant of the basement. Annoying when they begin to beep at night and I have so many to eliminate which one is beeping but early detection is key

    We currently only have one up at end of hall by our rooms and we had lite a fire today Christmas morning using wood , we normally use the clean logs man made. Well the fire was beautiful with real wood in our wood burner and sounded amazing. Well next thing I slightly notice smoke linger and alarm went off . We had to open windows and doors of course to get out smoke, the fire in wood stove kept it warm but was impressed that the light smoke that started set off the alarm down hall ... I def. recommend all to purchase. We will be putting up others for sure.

    Very pleased with this product
    I had finally had it with trying to put 9 volt batteries in a smoke alarm over my head while standing on a ladder. I selected First Alert because it uses easy to insert AAs and because my 20 year old alarms had not included a carbon monoxide detector. They were easy to install, even for this senior female. It's hard to tell how well they work. I hope I never have to find out, but I feel much safer with new alarms installed and I'm happy with the quality.

    Great product, great price
    I purchased this product because it had the dual function for both CO2 and smoke. I wanted the photoelectron smoke detector to stop false alarms in the kitchen and so far it has done the trick. The unit I put upstairs outside the bathroom has actually chirped from the steam after a hot shower. I run the exhaust fan and I can't see the steam however the smoke detector does. Impressive.

    I have just installed the First Alert alarm mentioned above, and I have high hopes that it performs well. Obviously, this is the type of device that you have in your home and yet hope you never are in the position to have to depend on it. Kind of like an insurance policy. You buy it, stick it in a drawer, and hope you never have to look at it. The installation of the alarm went very smoothly and it test well. So far , so good

    Just purchased my smoke and carbon monoxide detector - so far it tests well as expected. Will hopefully never be needed for a real event. Appreciate the combination unit - purchased one for main level and basement.
