      Q:Is the light that flashes every 10 minutes red. mine is a red flashing light
      by|Jan 8, 2024
      1 Answer
      Answer This Question

      A:  Hello. Are you sure this is the alarm you have? This is the I1040 model 21027488, the small 4 inch alarm with 10 year battery.

        Q:Does humidity set it off?
        by|Jul 19, 2023
        1 Answer
        Answer This Question

        A:  Hello. Enough steam or heat or humidity can set off the alarm or make the alarm more and more sensitive, yes. One of the locations to avoid is in very humid areas (above 95% RH, non-condensing). Moisture or steam can cause nuisance alarms. Another location to avoid is in an area where the temperature may fall below 40ºF or rise above 100ºF, such as garages and unfinished attics; this should also include electrical boxes exposed to these environments.

          Nice little smoke detector, good value.
          My 3 family was inspected by the state of N.J. It’s done every 5-years. They need to reinspect because I had the 9 volt battery smoke detectors. She informed me now the smoke detectors must be sealed.So no one can remove battery. The battery must also have a10 year life.To comply with new laws. These Kidde do. They are also UL Listed which is a plus. They fit all the criteria. The date on the smoke detector is 2022 Sep. 23 so a little over 9 months old Not bad,So I’m happy.

            Poor Battery Life
            I bought this in April 2020. Says it has a 10-year battery life. Mine is at low battery chirp, barely made 2 years.

              great little smoke alarm!
              [This review was collected as part of a promotion.] Love the Kidde 10 Year Battery, Ionization Smoke Alarm. Is a cute, smaller size. Is super easy to install and activate. Tested it and it works well! Nice and loud too. Love, love, love the 10 year battery! I can set and forget. Will still test it a couple times per year though, of course.

                Great Battery Life
                [This review was collected as part of a promotion.] I love this Ionization sensor smoke alarm. I especially love that the battery last 10 years. All of the other fire alarms I had before this, it seemed like I had to replace the battery at least once a year, so I am so excited to be able to just put it up and then not have to worry about the battery for a long time. I also love how small it is. It is really loud, so if there was ever a fire you should be able to hear it easily. The only thing I did not like about this alarm, is it didn't have the option to wire it in. I prefer mine wired and also battery operated so then you have a backup if one fails. Overall, I would highly recommend this alarm.

                    Small but powerful unit
                    [This review was collected as part of a promotion.] I was very shocked and surprised at the size of this powerful unit. The instructions were easy to follow…literally a twist of the cover and the battery starts it’s 10yr time. Only time will tell how long it really lasts but very impressed you don’t have to keep changing batteries. I tested it, it’s loud and alarms during a tests. Love love love especially the size.

                      [This review was collected as part of a promotion.] Compact, light, easy to fit and I love that I don't have to change it for 10 years. The quality is excellent and you can not go wrong putting this smoke alarm in your home . The sound is loud and it detects smoke quickly.

                          50% failure within 3 years
                          Bought four of these for my home, within 3 years two of them have randomly (not at the same time) started going off as if there was smoke (3 beeps and a pause). The only way to stop the noise was to permanently disable them. We tested about once a month, and cleaned them annually per instructions. But they’re not meant to last 10 years apparently.
