Questions & Answers

If alarm goes off from cooking can you take out battery then put it back in after smoke clears

No fire just cooking and gets smoky in kitchen
Asked by: Steve
Hello Steve. Yes, you can continue to use the alarm. We would recommend vacuuming out the alarm around the side edges with the hose of a vacuum cleaner just to get out any dust or soot or particles of smoke that might have gotten into it and might make it more sensitive in the future. But there is no issue with continuing to use the alarm. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

You mentioned that this item cannot be sent to CA, yet you also said order online and can be sent to and picked up at my local store in Los Angeles, CA Which is true? Is this comb smoke & CO alarm legal to use in Los Angeles, CA?? Thanks for your info.

There is probably an issue with your locality about shipping lithium batteries to mailboxes or something. Just a guess...

I tried rechargeable batteries after my alarm stopped working. Does rechargeable batteries work with this device?

Asked by: NkeyaPC
Hello NkeyaPC. No, they will not. Our alarms have a unique way of testing the batteries and rechargeable batteries will not test properly in the alarm. We would recommend Energizer Max E91 alkaline batteries or the Kidde AA alkaline batteries. The Duracell AA alkaline batteries used to be compatible with our smoke and carbon monoxide alarm; however Duracell made a design change to their AA alkaline batteries that while they feel is a design improvement, the design change takes the batteries out of the specifications that the alarm is looking for in batteries. We apologize for any inconvenience and the batteries are available on this website. Energizer Max E91 are Model # E91MP8ACS, Internet #206520631, Store SKU #103328 and the Kidde batteries are the Model # 21025831, Internet #205976053 .

Battery Operated Combination Smoke and Carbon Monoxide Alarm with Voice Alert is rated 4.5 out of 5 by 269.
Rated 4 out of 5 by from Here she is, just hanging there looking pretty and blinking at me with her beautiful red LED ever... Here she is, just hanging there looking pretty and blinking at me with her beautiful red LED every 60 seconds to let me know that she's checking for smoke and CO... she's mesmerizing, and has provided hours of entertainment so far! And if you ever get lonely and bored, just push her test button for some extra excitement as she will speak to you/beep at you. Though, I must say, she's not much of a conversationalist, as she just repeats the same rather monotone phrases ("Warning, smoke detected"; "Warning, carbon monoxide detected") over and over with beeps in between. I think she's hard of hearing because she speaks/beeps loudly and doesn't respond to verbal input. I'm going to have to deduct her one point due to the lack meaningful conversation; oh, and due to the fact that her sensor has only about a 7-year life, thus requiring periodic replacement. I'd prefer a longer term relationship. She is, however, relatively low maintenance and low cost with just periodic battery replacement (2 AA) which is a characteristic I like that in a lady. She replaces my previous Kidde smoke & CO detector, which conveniently let me know she needed replaced in the middle of the night with incessant beeping (she will also let you know in the middle of the night when her batteries need replaced). I'd prefer more traditional "honey-do list" left for me on the frig or the kitchen counter in the morning, but seeing as she doesn't have hands, I'd settle for a note sent via e-mail or text. I do like the fact that this newer model has access to battery compartment from the front of the unit; no need to remove it from the wall.

I have spent so much money on either the smoke alarm and carbon monoxide and both have failed. Now I don't have to worry if the alarms are going off because they need new batteries or is a dangerous situation about to erupt. I have both alarms in one unit. The house it not cluttered with one of each alarm all over the house. My alarm talks to me it lets me know fire or get out of the house. I truly recommend this product, it saves you from a lot of stress.

Rated 5 out of 5 by from Worked in a CO emergency We purchased two of these when we bought our house. Our heat exchanger in the furnace went and at 1:30 AM we were awaken by the detector in my baby's room "beep beep beep Carbon Monoxide!" At first I thought it was a fluke because nothing seemed to be wrong, so I reset the detector and went back to bed. One minute later the detector went off again. Then I knew something was very wrong. When the firefighters arrived they said without these detectors, me, my husband and my two sons (16 months and 10 weeks) would have died. I would recommend this detector a million times over. My family owes their life to this detector.

I Found this unit to be easy to install and testing just as instruction states. I see no malfunctions in this unit as yet, and do not expect any. This is my first combination unit but I have been using both separate units for more than 35 years. This Kidde unit which I used to replace a Carbon Monoxide unit that malfunctioned after 8 years of service.

It was easy to install but it's very sensitive so it's constantly going off I'm replacing another smoke detector that my nephew never hears when it goes off and it doesn't go off when it should all the time so I rather have one that go off at the first scene of smoke and heat than not go off at all

I like that you don't have to take it down from the ceiling to replace the battery. The smoke alarm I had previously was a Kidde, and it worked fine. I loved that this one just screwed onto the base I already had mounted on the ceiling. This saved a lot of time.

I had a fire inspection and inspector said I needed ones with 10 year lithium batteries. So check your local fire code . But did work and were easy to install, also easy to uninstall.

The only negative was that Home Depot does not stock this and I had to order it online and then had to pick it up at the store to avoid shipping charges.
