Could this be used as a portable unit for travel?
Asked by: Traveler
yes. I would remove the batteries while in transit. I'm not sure if it will activate in a suitcase or not. Could be annoying.

Why the sporadic beeps?

We have had the unit since summer. Never had an issue. Two nights ago it beeped one single beep. A second or so later beeping sporadic and stopped nothing after. The next night nothing at all. Tonight the same beep pattern as the first time. The alarm light detecting co isn't lit up at all. Can't tell if the operate light is blinking or not.

Code One Battery Operated Carbon Monoxide Detector (6-pack) is rated 4.5 out of 5 by 988.
Rated 5 out of 5 by from It actually got put to the test and worked! Well, since it's very difficult to review/test a carbon monoxide detector...I actually had a situation in my home and it worked just like it's supposed to. We were getting our carpets cleaned and the their van was in our garage with engine running. (of course garage door was open!) Over the duration of the cleaning, exhaust began entering our internal garage door into the house and this thing went crazy. Took it out back to fresh air outside and turned off. Passed the test! Just a heads up for those looking to purchase one...go for this battery operated and NOT the one that plugs into the wall with a battery backup. Any time a dog or kid rubs into the one for the electrical outlet, it goes off. Every couple weeks, goes off. Piece of junk! This one on the other hand, is small, looks good, and in my situation, it worked great. Gives me a piece of mind for family safety.

I called their customer service because I had a question about the replacement batteries and was very pleased with the response. Also, the warranty is for 10 years. Therefore, it is supposed to last 3 years longer than the one I replaced.

Of course, it's impossible at this point to know how long the non-replaceable battery will last (the unit also has other batteries which are replaceable) or whether or not it will actually alert me if there is an actual carbon monoxide threat, but the unit was a good price and easy to buy.

We opened the windows to air out the house and set this detector on the counter. The alarm never sounded but it’s an assurance we need should a similar situation arise in the future.

Our last Kidde Detector had to be replaced because of age and I knew the Kidde brand so I purchased another one as the replacement. We feel better with the alarm and just thankful it has not had to alert us over it's lifetime.
