PRODUCT OVERVIEW

Model # SCO5CN

Internet # 202433891

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.

CUSTOMER REVIEWS

Rated 4.3 out of 5 by 67 reviewers.
Rated 5.0 out of 5.0 by 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.

Rated 5.0 out of 5.0 by 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. February 18, 2014
Rated 4.0 out of 5.0 by Happy to have this added protection I know there are better products on the market than this one but for the price I feel like this is a great compromise. It has the functions I needed and a price I could afford. I wanted to have two units, one for our bedroom/kitchen hallway (back of house) and one for the front of the house so this was a good price point. There is a green light that flashes to let you know the unit it connected to power/functioning but it doesn't align with the unit's opening and is not easy to see. That is the only issue I have noticed so far. May 19, 2015
Rated 5.0 out of 5.0 by alarms are very easy to install and all the mounting items needed were provided with each unit. Alarm is very easy to install. In fact I removed my existing smoke alarms and the new ones alarms fit in the exact some holes. Light and very easy installation May 29, 2015
Rated 5.0 out of 5.0 by Great Item Great product easy to install good value for the money May 26, 2015
Rated 5.0 out of 5.0 by A Super Buy This product so easy to install and works very easily. The problem with this unit is that is has a self testing that activates at any given time, even in the middle of the night. So many Customers are complaining by saying its not a good unit. On the contrary is an excellent unit I have 6 throughout my house for the last 5 years up to date. What I love about the unit is that you can program it to speak the area like, Hallway, Living room, Bedroom where the problem is. So when the unit does a self test in the middle of the night its okay it doesn't not mean that's its defective. In order to disarm the self testing you pull out the Batteries hold the test button and push the Batteries back into place, this process will eliminate the self testing. March 29, 2014
Rated 2.0 out of 5.0 by only a year! It is December 1st 2014. The manufacture date on my unit says 2013 Jul 02. The unit is chirping. I read the instructions on what the sequence of chirps means and it says to replace alarm. Wow. That didn't last long. December 1, 2014
Rated 1.0 out of 5.0 by Do Not Buy! Alarms Trigger For No Reason. I've had this alarm for less than 90 days and it has malfunctioned (i.e. gone off for no reason) multiple times at all hours of the day and night. The beeps are loud enough and piercing enough to wake us up, which would be great if there was an actual fire or a carbon monoxide leak. It's not so good when it goes off for no reason. Definitely disappointed with this product and will be returning it for a different model. October 2, 2014
