Customer has been confirmed to have purchased the item from Walmart.

We already have one in our upstairs and put this one downstairs. The life of this product is about 7 years and has to be replaced as a safety. We had a tragic fire close by in which 5 died with only one detector in house with no battery. This uses double A batteries and is very simple to install and just twist off top to install new batteries. I think this should be a must and hopefully fire departments of other organizations will volunteer to install or check houses or apartments yearly.

I've had this detector for 2 years and I've changed the batteries every fall. Not a difficult task since the attachment ring stays on the wall and you just twist to remove the detector. I've hit the test button once a year to make sure it was still working since thankfully it never went off. A couple of nights ago, I closed the damper on my chimney when I went to bed, thinking that the glowing embers weren't a big deal. Well at midnight, the alarm was screeching "ATTENTION! CARBON MONOXIDE DETECTED!" I have to to say, the beeps before the verbal alert were starting to wake me, but those words brought clarity to me instantly and I was up and out of bed opening windows! I reset the alarm and then had to go to the website to look at the manual to see what to do next. This is a great alarm for the money, and definately saves lives!

This alarm saved my house, I was frying chicken on the stove, and I fell asleep on the wreck room sofa from being so exhausted, An oil fire started and caught the overhead on fire, which also caught the the curtains on fire. The alarm went of in a Code 3 pattern and blared "ATTENTION, FIRE! FIRE!" It woke me up on a different level of the house. I ran up the steps and grabbed the Kidde Kitchen fire extinguisher (I ALSO RECOMMEND) and quickly got the fire out. Thank You Kidde.

I cannot tell how to remove and replace the batteries

  • A. Hello. There is a battery door on the front of the alarm. Slide open the battery door and put in new Energizer E91 batteries. There is a sticker on the bottom of the battery compartment with a plus and a minus to show how the batteries go in.

  • A. Turn the unit to the left on the base or counter clockwise and it comes off easily. Pop out the batteries (3) and it shows which way to put in the new batteries. Good idea to change the batteries once a year.

  • A. The top comes off with just a twist and very easy to install new batteries which are in this portion. Once new batteries installed just a twist and it is back in operation. You can test the alarm to make sure that it is working.
