Q:Will this alarm connect with the battery powered, wire free alarms that Kidde makes?
by|Apr 9, 2024

Answer This Question

A:  Hello. No. You will want the P4010ACSCO-W model 21028759

by|Apr 18, 2024

    A:  I don't think so. This is a standalone battery model not designed for interconnection to other units. Those models by Kidde would say "interconnectable" and would be hard-wired only.

        Q:Can lithium batteries be used in this product
        by|Mar 4, 2024
        1 Answer
        Answer This Question

        A:  Hello. No. The unit has a unique way of testing the batteries and must use the alkaline AA batteries of the brand and model listed in the owner's manual. If you want an alarm with lithium batteries then you will want the P4010ACSCO model 21029893.

            Performance and Durability
            We have used Kidde products for decades in multiple homes and have always been happy with the performance and durability of the entire line. We have been waiting since September 2023 for this to ship. I have tried multiple times for follow up and have never heard back. I am not sure when we are getting these. Until then we will wait even though we have two missing smoke detectors in the house that need replacing.

            Love these combos
            With 25 properties under my management I often grab new items to try out. We just built 7 new houses and in one of them the hardwired alarm kept going off so I decided to grab this one for the common area since it's a voice alarm. So far so good. It looks a bit bulkier than the other flat ones, but i just hope that means the internal components are beefier and better. Tested it multiple times and cleared any spiderwebs and dust from the area. Hopefully it lasts 8+ years!

            Color Doesn't Match - NOT WHITE
            The white Kiddie FireX combination Smoke & CO alarm is actually off-white (almost almond), and substantially different than the white Kiddie FireX smoke detector. These look old and crappy on a white ceiling. Clearly no quality control , buyer beware. The picture does NOT do this justice, looks much worse in person.

              Safety first
              I did receive the Kidde smoke and carbon monoxide alarm but not aware it’s voice activated. We have it installed in our kitchen. We have it for safety and feel it’s definitely an asset to have. It blends into the ceiling nicely and is not overly large. Kidde is a very well known and reliable brand so we feel it is an excellent item to have in our home.

              Great combo alarm
              This Kidde hardwired with battery backup setup is a great set up whether you have a hardwired system or even if you want to use the battery. If you can hook it up into your current wiring, it’s all set with the wires you need, and also provides you the peace of mind that a battery will always be available even if you would lose power or have some other issue. It’s easy to install with provided screws and plate, and the alarm clicks and turns right into the plate once mounted. Super easy install.

                Kidde Hardwired Interconnectable Smoke and Carbon Monoxide Detector with AA Battery Backup
                The Kidde Hardwired Interconnectable Smoke and Carbon Monoxide Detector with AA Battery Backup. This dual-purpose safety device protects and alerts from two hazards, smoke & carbon monoxide gas. There are generally Two types of smoke detection methods Photoelectric, for better detection of larger, visible fire particles found with slow smoldering fires, and ionization detectors, that may detect small, less-visible fire particles from fast-flaming fires, there are advantages in both types. This model utilizes Photoelectric sensing technology that senses visible fire particles found with smoldering fires, and an electrochemical sensor to detect carbon monoxide, which you won't smell or see, but is deadly. This model is Powered by 120VAC (60 Hz, 42 mA max) using a wire harness that is proprietary, which will result in requiring a rewiring of your power supply to use the Kidde Specific connector. I believe there is an adapter that Kidde sells that will allow you to use another brands connector. I do not know why this was necessary as both connect using 3 wires to interconnect to other compatible alarms. In my case, my home wiring is not interconnectable, and I use only 2 wires to power the device. The included mounting bracket makes installation quick and easy and includes 2-AA batteries to provide smoke detector-carbon monoxide detector combo backup power, if the 120v power goes out during short-term power outages. The device measures 5.60” in diameter x 1.93” deep, and weighs 0.550 lb. Overall, I like the looks of the Kidde Detector, and the features it offers, however, I would like to see the 120v connector to be standardized.

                Alarms Hallucinate Wildly
                When the power goes out they alarm for CO. If you reset the alarm for fire. We don't have gas, there is no smoke. Even our water heater and oven are electric. Nothing uses combustion. It is really telling when a manufacturers review on their own website is 1.3 out of 5 stars. Even they admit these are garbage. Nothing against Home Depot but this trash belongs off the shelves. Even Kidde is aware these are bad.

                    Terrible quality
                    I own multiple apartments in the Boston area. For years I have been tortured with the constant failure of the Fire Ex smoke and combo smoke co detectors. I replace the batteries annually now I have to increase battery replacements to every 6 months to get ahead of the low battery chirping. At best I get five years out on any alarm, often times less than a year. When I try to return them to Home Depot They say I need the original packaging which is impossible to store.

                    Response from Kidde ExpertSep 26, 2022
                    Hello. Yes, these alarms need their batteries replaced every 6 months to a year. The alarm tests the battery by running on battery alone for a fraction of a second every 30 seconds to a minute as part of testing the batteries and this does wear down the batteries over time. The new batteries do need to be the alkaline AA batteries of the model and brand listed in the owner's manual. Other batteries can read as low when they are not. Batteries close to their use-by date can sometimes not be powerful enough for the alarm or not be powerful enough to last 6 months to a year. We would strongly recommend the AA alkaline batteries as listing the owner's manual with a really good use-by date of at least 4 to 5 years out. Batteries bought today in this range would have a use-by date of 2026 or 2027 or beyond. A really good use-by date of at least 7 to 10 years out can be used to sometimes get a bit longer use out of the batteries. Lithium-enhanced AA batteries can not be used.
