Questions & Answers

Q:How do you install the batteryp

1 Answer
Answer This Question

A:  Hello. On this alarm, the battery is preinstalled. To activate the battery, slide the alarm onto the bracket tightly and that should turn on the battery. Slide the alarm down over the mounting plate until it snaps into place. That should activate the alarm.

    Q:While the battery will last for 10 years does the sensor element also last that long?

    Answer This Question

    A:  That’s a good question but I’m sure it will depend upon the recommended maintenance. Any brand/model will last longer and minimize false alarms by following the maintenance schedule and vacuuming the sensor regularly. Have you checked the manual that’s available online to see if the sensor is rated for 10 years? Otherwise I would contact the manufacturer. Best of luck.

    by|Aug 9, 2022

      A:  Hello. Yes. The CO sensor in this alarm is UL listed to last for 10 years from first use.

        Q:Will this alarm detect propane leaks? We have a new house and gas logs were installed which uses propane to work. We need a detector for this and wanted to know if this one would alert us if we had a propane leak. Thank you very much for responses.

        A:  Update. Look great a “ Carbon Monoxide and Explosive Gas Detector”. They do make those. Kiddie and first alert make them. 

        by|Dec 4, 2022

          A:  This detector is designed to alert for carbon monoxide, which is a product of combustion. It's not designed to detect propane or natural gas.

          by|Mar 8, 2022

            A:  No, it is a carbon monoxide detector not a propane detector.

            by|Sep 27, 2022

              A:  Not an expert but all the natural gas and propane leak detector alarms I have seen are not CO detectors. Nor the other way, CO and Smoke detectors do not detect nat gas or propane. Different chemistry. 

              by|Aug 27, 2022

                A:  Hello. No. This alarm would alert you if the gas fireplace didn't burn correctly and there was carbon monoxide leaking into your house. For detection of propane gas, you would need an explosive gas detector.

                    A:  wait, I was reviewing the wrong product. This does not detect smoke..sorry for the confusion

                      A:  yes, it detects smoke

                      by|Mar 1, 2022

                        A:  Hello. No, this is not a smoke and carbon monoxide alarm. It just a carbon monoxide alarm and does not detect smoke. You should still check with your state and local fire and Building/Safety codes for the installation of carbon monoxide alarms as well as the smoke alarms you are required to have in your home.

                          Great Carbon Monoxide Alarm!
                          [This review was collected as part of a promotion.] I got this awesome Kidde Battery-Powered Electrochemical Carbon Monoxide Detector and feel very protected now! I have had a Kidde Smoke Alarm for the past 10+ years and have been very satisfied with its performance. I got this carbon monoxide detector to add to the protection and it was a breeze to install. It has a digital display, a peak level memory, along with a Sealed Lithium Battery. I really like that the Kidde Worry-Free Carbon Monoxide Alarm has a 10 year warranty! The included User Guide is really easy to understand and contains complete instructions for installation. This detector has a Peak Level Memory that notifies of a CO event in the last 14 days. I highly recommend this Kidde CO detector!

                            Very impressive device!
                            [This review was collected as part of a promotion.] This device is really quite impressive to me! Not only can it be hung on the wall but it can also be placed on a table top! This is very easy to set up and battery is included! A 10 YEAR battery! That is incredible to me. When testing it is extremely loud! If you have an alert to move to clean air you will notice it because it is loud! Which is exactly how it should be when you health is at risk! I couldn’t be happier!

                              Easy to install, in fact we used the mounting holes from the previous carbon monoxide detector to install this. It cost pretty much exactly twice as much has the Kidde detector with replaceable batteries and was well worth the cost and hassle of replacing batteries every year. I would buy it again...but not for another decade.

                              Super easy install
                              What an easy install it was! Just 2 screws into the back plate to the wall and slide the CO alarm in. That's it. Nothing difficult at all. With a 10-Year battery I don't have to worry about it. There is no battery to change when the battery does die out. You would just buy a replacement. A quick tip, make a calendar reminder on Google Calendar or whatever app you use to check on it 10 years from now.

                              Piece of mind and 10 year battery. Great deal.
                              Piece of mind and keeps on working for up to 10 years of continuous protection. I have an older heating system and also use a secondary heating unit which is a wood pellet stove in the family room over the winter months. I am always concerned about the possible buildup of the deadly carbon monoxide gas in my home. Better safe than sorry. This small wall mounted unit is easy to install and sets up as soon as you mount it on its wall mount. Two screws hold it in place and then let it do the work for up to the next ten years before the lithium battery wears out and replacement will be required of the alarm system.I mounted this unit in my living room. I like its modern sleek look and compact size. It is not an eyesore and placed in plain sight and can be heard from anywhere in my home should the alarm sound it can be heard to alert us of danger

                                Sensor works exactly as expected
                                  First one lasted ten years
                                      Satisfied with purchase, I have used this detector in the past and plan in purchasing more.
