Tools and Hardware Reviews of First Alert SC05CN Battery Operated Combination Carbon Monoxide/Smoke Alarm

Customer Review: An utter waste of plastic and silicon!
Summary: 1 Stars

While at first I was impressed by the dual ability to sense carbon monoxide and smoke, the great feeling I initially had upon buying this product faded fast. We bought this smoke/carbon monoxide alarm to replace a smoke detector that quit working after about 18 months(also from First Alert) in our master bedroom. I have a Kidde Carbon Monoxide/Smoke alarm in the basement which has worked great for 3 years without any problems. However, they did not have that one at the home improvement store I bought it from, so I settled on this gem.

Long story short, about 3 months after buying this detector it started chiming 3 times at about 3 AM after a grueling day. Evidently, it was only a coincidence that the time roughly matched the amount of chimes, so this was not helpful. I was able to crawl on a step stool and pull the thing down figuring perhaps the batteries I put in it were old and near death. So, giving this the benefit of the doubt, I placed two brand new batteries in there and placed it back on the ceiling, sleeping soundly under my blanket of smoke and carbon monoxide protection. Two days later, same stinking thing. After overlooking the obvious sticker on the back of the thing, I scoured the bowels of the internet only to find that the self-test had determined that the detector had failed and chimed to let me know so it would be replaced. I'm replacing it alright, with another make. Moral of the story: Don't buy a first alert product. They are awful. How do you put something this dreadful out on the market. I basically threw away $50+.

Customer Review: Location Dependant?
Summary: 1 Stars

I have rental properties and I decided to upgrade all units to have monoxide detectors. I decided on this unit because it is a two in one device and it used double AA batteries instead of the nine volts. My tenants keep complaining that these devices keep beeping. I looked on the back and 3 chirps = bad detector. I took a few of them down, put up the old ones and brought them to my home. They have not chirped since. Something about the other place is making these detectors fail.

Another thing is that I did not notice this but there is a 5 year life on these detectors and then they will chirp without any choice but to replace them. So even if yours works at first, you only will get 5 years out of it. I bought a total of 7 of these that cost me a few hundred and now I need to look for replacements. I wish I left all the old smoke detectors in.

Customer Review: Stopped working within a month.....
Summary: 1 Stars

I thought maybe a bought a dud but after reading previous reviews, I had the same issues. Within a month mine started beeping to replace the alarm. I foolishly thought this couldn't be and replaced the batteries. Within a couple days it was beeping again. I paid over 30 bucks for this and now I'm here again shopping for another alarm. Stinks to have to shell out all that money again. I'm getting a different brand this time around. Oh well....

Customer Review: junk
Summary: 1 Stars

I bought two of these last year. Within a few months, we started getting false alarms. Three chirps in a row. Sometimes they would stop on their own. Other times, I would have to take them down, take out the batteries, and hang it up again later.

Each time, I tested the batteries. Each time, they were fine. I ever replaced the batteries a couple of times, just to be sure.

Don't buy these. They'll drive you to drink.

Customer Review: Not so good...
Summary: 1 Stars

Affordable, easy to install, uses common batteries. Seems to work but hopefully it'll never have a reason to go off. This is a photo smoke sensor, not an ionizing fire sensor. Wasn't clear to me in description. This isn't necessarily good or bad though.


Died after a year and a half (new batteries didn't fix it), it just kept beeping indicating an internal problem. Weak Sauce!
