Q:Can these integrate with normal Kidde alarms? So I could have, say, one smart alarm on each floor and then the rest of them could be normal, less expensive units?
by|Mar 18, 2023
Answer This Question
A: Hello. Yes. Note that if a alarm goes off that is not, quote, "smart", then while it will set off the smart alarms and the smart alarms will set off the app, the app will not be able to tell you which alarm is going off, only that there IS an alarm going off in the circuit. You will not be able to hush an alarm that is not "smart" with the app.

Q:What is the best smoke /carbon detector for my garage
by|Mar 17, 2023
Answer This Question
A: Hello. We don't have a smoke alarm or a carbon monoxide alarm for the garage. The garage gets too hot, too cold, too much dust and insects, and too much chemical odors all of which can cause the alarm to go into an error mode or give false alarms. The only alarm we have for the garage itself is a heat detector HD135F model 21029895. It will go off when the heat near or on the ceiling exceeds 135F.

Q:If I replace 4 wired First Alert model SA303 will this unit work?
by|Mar 3, 2023
Answer This Question
A: Hello. You can use any of the Kidde current hardwired smoke alarms to replace your older alarms. You will have to take down all of the older alarms before putting up any new alarms. Our alarms won't work with First Alert alarms. You will have to change out and rewire the wiring harness plugs at each location. There are no adaptors for the wiring harnesses you have now. You will have to change out the mounting brackets at each location but that will just take a screwdriver to change out.

Reached “end of life” in less than a yesr
We had the detectors professionally installed when our house was rewired. Less than a year later our kidde app issues an alert that one of the detector has issued end of life and should be replaced. Unfortunately warranty requires consumer to play for shipping to replace.

It's easy to setup.
I think it'll be a good alarm. Hopefully, it won't ever have to do its job. It's kinda hard to review something like that without a real event happening. I can say that the install was easy, including the wifi setup. The app is easy enough to use. It's setup with my Alexa ecosystem, which was also easy to setup.
The only issue I have is that I did have my router reboot every night, but I guess this alarm doesn't really like that. I would need to reboot my router again in order to get it to reconnect to the network. I just decided to stop the scheduled rebooting on my router. It has maintained its connection since then. It doesn't rely on the connection to do its job, but it wouldn't be able to send the alarm to all connected devices without the connection.
Overall, I think it's pretty good, and I plan to eventually install one in every bedroom in the house.

Many features, but not all consumer-friendly
This product has a lot of potential, but it seems to be targeted at builders, as the manual is not particularly consumer friendly (lots of warnings, tiny diagrams, and a focus on interconnected alarms). The interconnected features seems to be a main selling point of this product, and because it requires whole-home wiring, it's not something you can easily retrofit. Having just ordered one of these alarms, I felt like I wasn't the intended audience for this product.
Ultimately, I wasn't able to use this because my old smoke alarm is on a 4-wire system, and this is a 2-wire system, which is something I hadn't researched beforehand. In the end, I think I'll just stick with my battery-powered Kidde alarms for now! But for homeowners with existing 2-wire interconnected smoke alarms that want to upgrade to CO detection or WiFi control, this could be a good option.
This Kidde (great brand!) carbon monoxide and smoke detector comes with everything needed to hardwire it into the house. Our 10-year-old detector stopped working, so this seemed to be the best choice for us as we are getting old. It hardwires easily into an existing detector connection. We really like the voice alert that is part of this unit. It can also be set up for WiFi, which we have not yet done. Lots of safety bells and whistles on this one!
I replaced my old smoke detector with the Kidde Smoke and Carbon Monoxide detector. I was very pleased with how easy it was. The physical mounting of the hardware was right about 5 minutes. I unscrewed the old plate, undid the wire nuts and then put the new mounting plate back in its place and put the wire nuts on the new connector. A pushing the new detector flush and then giving it about a quarter turn and the hardware was mounted. It took me longer to find the step stool. From there, I just scanned the QR code to get the app. It installed on my phone and prompted me to create an account. Once I set up the account (less than 3 minutes) I scanned the QR code for the actual detector, joined it to my WiFi and it is done. From start to finish was right about 10 minutes. Now I am not only protected from smoke but also carbon Monoxide. I can check it with my phone and even get alerts if an event is detected. It was super simple to install and has all the modern features you would want with a detector.
This is a great detector and a must have in a home where you're tying all alarms together. The red wire does that, trip one alarm and all of them go off, which is a great safety feature.
Online monitoring is also a must have for residences where you don't occupy the premises too often and yet you want to receive instant notification, the same way a professional alarm company will notify you in case of a fire.
The connection is very good and stable with both 2.4 GHz and 5 GHz Wi-Fi, as well as in high traffic DHCP managed environment.
Reconnecting after power failure is instantaneous and smooth without any lag.
Resetting the connection in case of changing router settings is also very intuitive and fast, by re-initializing the connection by resetting the network controller, by holding the button depressed until you hear 3 beeps. There is an easier way to connect using a QR code, but this didn't work on my end due to a few security settings on my phone.
The installation is possible with the back bracket and is meant to be used on a standard ceiling box, I used a low-profile plastic one and 3x14ga wiring. Technically, you can just make a hole in the wall so you can fit in the 2" wide battery housing inside, but I wasn't inclined to do that, so I can seal off any dust that may contaminate the sensors. In that regard, you need to clean with a vacuum the sensor at least once and year.
Weight of the alarm is 400 grams or 0.88 lbs., installation on a fiberglass panel of a hanging ceiling may be hard without some form of back support.
I was surprised the manufacturer didn't include a way to replace or remove the battery before disposal and there were no instructions on disposal in terms of reclaiming the lithium battery inside. There is a position, however, of the connector switch that shortens the batter terminal making it safe for disposal.
The smoke and fire sensor is photovoltaic and CO2 is electrochemical. Both sensors are known to outlast their 10-year prescribed lifespan, but yet the manufacturer used tamper proof screws so there is no advisable way of messing with one of the main safety features of your home. With the price of this alarm, replacing comes down to an amount of one coffee per year, so it is rather negligible expense for a long-lasting precise product that provides enough feedback and safety features to increase your overall home safety even without an overly expensive integrated safety system. In terms of integration, this sensor integrates seamlessly with both Alexa and Google assistant and few of the major IFTT applications. False triggering has been balanced very precisely so that not to have your ears ringing after a burnt toast, and yet definitive enough in case of a small fire, outputting even less smoke. CO2 alarm is sensitive, starting at 70ppm which is reasonable enough keeping in mind that CO2 is heavier than air and tends to stay low, while the installation of the smoke detector is usually high up. I was able to trigger the alarm with compressed CO2, in a steady stream directed toward the alarm.
The hush feature is a must have and works nice by pressing the center button, it disables the alarm and interconnected additional alarms for 8 minutes until you had the chance of airing the premises. Same feature works on the CO2 event triggering.
Alarm is distinctly loud by blaring a piercing beep at 85db, so even when testing you have to be mindful and have some form of ear protection.
There are some considerations that you must make if you live in area with frequent power outages and you running your power off a generator. The unit does not a built in power rectifier and therefore any sine wave that is not pure, such as sqaure, modified sqaure or modified sine wave, as well as high peak or low drop voltages, normal when you turn on the connection of your generator are likely to damage the sensor. Unlike most computers, TVs, radios, this sensor does not have features in place to protect itself from bad power, so you need to consider this when purchasing and installing.
Other than that, it is a great product and very nice and worthy upgrade of the safety features of your home, office, in residential or commercial application.

Nice smart home detector.
I got this to replace an older smoke detector I had in my house. With that being said it was fairly easy to install since I already had a spot and the wires ran to hook it up. Comes with everything you need to put it up. It's nice that it is a smoke and carbon monoxide detector, no need for two different units. it does stick out a little farther than my previous unit but as high as it is on the wall it's a none issue. I think it took me longer to set up the app than it did to install.
[This review was collected as part of a promotion.] The Kidde Smart home smoke and carbon monoxide alarm with app is the better way to protect your home. It has double the detection so that's double the protection for you and your family. It will alert you to both smoke and carbon monoxide with one alarm and it notifies you through an app.
I love that you can turn off false alarms when you're home with the smart hush. This is the only alarm that you'll need. Setup is easy. You scan the code on the back of the alarm and place it where you need it. I love that it has such a long life as well. I won't have to worry about changing the battery for ten years. That is important to me.
I highly recommend these alarms. They're easy to setup and very convenient.
