Tools and Hardware Reviews of Kidde KN-COSM-B Battery-Operated Combination Carbon Monoxide and Smoke Alarm with Talking Alarm
Customer Review: Does an excellent job
Summary: 5 Stars
The Kidde Combination Smoke and Carbon Monoxide Alarm is battery operated (it takes three AA batteries). It has an 85 decibel alarm and also features a voice alarm. In the event of a fire, the alarm will give off three long alarm beeps followed by a verbal warning of "FIRE! FIRE!" and the red LED light will flash. In the event of carbon monoxide, the alarm will give off four short alarm beeps as well as the verbal "Warning! Carbon Monoxide!" and the red LED light will flash. In addition to the smoke and carbon monoxide warnings, the alarm will notify you when the battery is low: the red LED light will flash and the unit will chirp one time, followed by a verbal "Low Battery". Finally, the alarm will last for seven years of cumulative use - at that point, the alarm will chirp culture 30 seconds indicating it is time to replace it.
I bought two Kidde Combination Smoke and Carbon Monoxide Alarms for my house (the first floor - I live in a ranch style house - and one for the basement) and I am very pleased with both. I like the idea of having both an alarm and verbal warning and while the alarm is loud enough to be heard throughout the house, it is not annoyingly loud (my prior carbon monoxide detector was obnoxiously loud). I also like having a combination of fire alarm/carbon monoxide detector and the alarm does a good job of having distinctive sounds for each problem. The alarm is sensitive and works well - while it won't go off for cigarette smoke, for example, t does go off when I cook buffalo chicken wings; I'm happy there is a "hush button" to shut off the alarm in cases like that. (this button will not work if there is dense smoke, so it is safe to use). The alarm is tamper-resistant, which will stop children (or others) from deactivating the alarm. I like the fact that the alarm lets you know when the battery is low and notifies you for up to at least seven days - this is a great feature if you are on vacation or away from home for an extended period of time and don't know right away that the battery needs changing. I also like the fact that the alarm will let you know when it is time to buy a new one. I wrote on the alarm the date I installed it, but it is still nice to have a reminder.
The Kidde Combination Smoke and Carbon Monoxide Alarm does an excellent job.
Customer Review: SAVED MY FAMILIES LIFE!!!
Summary: 5 Stars
We live in a 4 level split home. Our gas furnace is on the lower, 3rd level. Two years ago we had several smoke alarms, but only one carbon monoxide detector on the top, bedroom level of our home. One early Saturday morning we awoke to the voice of this alarm broadcasting, "WARNING! CARBON MONOXIDE DETECTED!" over and over again. I got out of bed and took the batteries out of the unit. By then my then 16 year old daughter came out of her room and was watching me. I told her to go back to bed, but she asked me why we weren't going outside to our designated emergency spot. I thought I was being a bad example after all the years of telling the children to get our of the house if an alarm went off. I didn't think there was a problem. I assumed the unit was broken or needed a new battery. I wasn't thinking clearly. So, I put the batteries back in to see if it would go off again. It did. She again asked why we weren't following the rules and going outside, so we left the house and called 911.
When the firemen arrived I kept apologizing for calling them to our home for an obvious mistake. I thought the firemen would tell us it was a false alarm. It wasn't. The heater core had cracked and was leaking carbon monoxide. The levels were high enough to make us confused, but not yet put us to sleep. Had my daughter not watched me handle the alarm I would have gone back to sleep without ever putting the batteries back in. We were very lucky to have my daughter and this CM detector.
The voice made everything so much clearer than just a siren. If it hadn't said "carbon monoxide" I would have left the batteries out and gone back to sleep because I couldn't see any smoke or fire and I was tired. I don't think I would have thought about carbon monoxide. It was well worth every penny. I now have CM detectors on every floor of my home. This talking carbon monoxide detector helped save my families life.
Customer Review: So far, so good

It was time to replace the battery on our NIGHTHAWK smoke detector and I realized that it had been manufactured in 1999! Checked the plug in NIGHTHAWK carbon monoxide detector and found that it also was manufactured in 1999. They both were working well when tested, but we've fortunately never had a fire or carbon monoxide experience, so the alarm warning was never utilized for evacuation purposes. We changed the batteries, but figured it was time to replace both units. After much research, the Kidde KN-COSM-B Battery-Operated Combination Carbon Monoxide and Smoke Alarm with Talking Alarm (also NIGHTHAWK product) was the clear winner. It was a little difficult to remove from the plastic shell packaging but was a breeze to install. The alarm will not snap into its holder without batteries in place, so on the day I was ready to install, I put in the (3 enclosed) AA batteries (must insert them in the order specified in the battery compartment) then twisted the alarm onto its holder and tested the alarm. All it's warnings functioned properly, so the old alarm was removed from the ceiling and the new base was installed onto the same ceiling location. The alarm was twisted into place and the it was tested a second time. My unit was manufactured five months ago but from what I understand, the 7 year self-destruction warning sounds 7 years from the date the batteries were installed. I personally would not purchase this in an opened package for that reason -- could be that someone inserted the batteries a year ago and returned the item. The included manual specifies that certain AA batteries be used and I don't know what occurs if one uses another brand. When I have time, I'll contact the company to check that out. I hope to only hear the warning "voice" from this alarm every time I press the test button but am comfortable with the security I feel knowing this alarm is functional. Its warranty expires in 5 years.Customer Review: It saved our lives

We bought three of these (one for each level of our home) about a year ago. I never really thought about it and just hoped they work properly. Last week at 5:30 am one of the detectors went off. I went down to our finished basement and it was yelling "Carbon Monoxide". We opened a bunch of windows, called Xcel energy and the fire department and left the house. Both the fire department and xcel arrived about the same time. They all walked through our home and said it definitely had CO inside. All of them said we could have easily died had we not owned these detectors. The cause of the problem was our 26 year old furnace. Ironically it was scheduled to be replaced this week with a new 95% efficient furnace.
I now feel so strongly about owning these things and replacing them about every 6 years that I decided to come out here and write a review on it. They work. They work well. And they probably just saved the lives of three people. I have no doubt about it.
Customer Review: Very Happy with the Kidde Smoke/Carbon Monoxide Detector 900-0102
Summary: 5 Stars
Easy to install the alarm's base mount on either ceiling or wall..... does include the installation hardware....... 2 small screws and 2 small plastic anchors.....also includes the three AA Energizer batteries..... I liked that, and the alarm is very easy to remove from the base mount which I really like because i like to take this alarm with us on vacation when we are staying in motel rooms. The alarm is small and light and it fits very nice in our travel bag. When we get back home it only takes about 5 seconds, literally, to reinstall the alarm back on the wall mount again...... easier than screwing in a light bulb. The hush feature is very nice too when you burn your toast...... and the alarm will also automatically reset itself after a few minutes of burning toast or bacon..... the alarm is very loud and if it doesn't wake you up, then you're probably already dead....i am very happy with mine.... and I very much recommend this alarm......
