Customer Ratings & Reviews

This was purchased to replace an expired and now non-available google nest detector. It was almost plug and play as all power adapters are included. No need to call an electrician. Plug the new adapter into the old plu and you re ready to go. Even the connecting ring doe not have to be change. I had no issues with bluetooth connectivity.

Overly sensitive to steam, don’t put near a bathroom. Otherwise it’s a nice alarm that’s easy to install, app is straight forward.

I replaced three Nest smoke alarms with these all ready and they work great and used the same bracket as the Nest alarms. Very easy to use the new Resideo app that First Alert uses.

After 10 year I needed to replace my Nest Protect Smoke Alarms with a newer version from First Alert. It was quite easy. Like the look and ability to work in conjunction with the google home app. The only downside is that the new alarm does not have the nightlight feature that was in the Nest Protect!

All of my Nest Protects have reached their 10 year expiration so I decided to continue my connected home with these. Nest did all of the R&D and set the gold standard on features. It baffles me why First Alert did not incorporate them into these devices. Relative to the Protect, these seem too expensive since they lack features and a desirable design language. I miss Pathway lighting most! A feature First Alert states they are considering on a future model. Not on these. What I like is their compatibility with the Protect mounting bracket and a wiring connector for a seamless, fast installation. It took me longer to get the ladder out than installing.

Purchased bc one of my nest detectors malfunctioned and needed to be replaced so purchased first alert for compatibility with my other nest detectors. So far its been great, it was super easy to install (works with nest wall mount that was already installed) & set up. One functionality i miss is that the nest use to light up when motion was detected, i wish the FA had the same function.

I was quite impressed with the ease of replacement with my expiring Nest Protects. It was literally plug and play. The First Alert app is intuitive and has a great guided setup as well. I am also pleased how well the devices integrate into the Google Home app. The only knock on this device is the lack of a path light. Mine is located in my hallway and I miss having it light up when I walked by. Other than that, I've had it up for almost two months without any issues.

Quality device and works with Google Home. Easy to add, although you have to add one more app to your phone. Wish it had a spotlight like the Nest App. And be careful to make sure you get the wired or the battery option depending on your need.

I bought this as a replacement for a Nest Protect that was failing its hardware self-check. The included wiring adapter connected to the existing Nest harness and the unit attached to the existing base plate as well. Adding it to Google Home (after setup with the First Alert app) was also smooth. The unit doesn't have the night-light LED feature that the Protect has, though. Other than that, a drop-in replacement for the Nest Protect.

I’m very happy with this First Alert hardwired smoke and carbon monoxide detector. Installation was straightforward and the instructions were clear and easy to follow, which made the setup process quick and stress-free. The companion app is a great addition. It makes monitoring the detector simple and provides peace of mind by allowing you to check status and receive alerts directly on your phone. As an added bonus, it integrates smoothly with Google Home, which fits perfectly into my existing smart home setup. Overall, this is a reliable, well-designed detector that combines safety, convenience, and smart features. I would definitely recommend it to anyone looking to upgrade their home safety system.

Bought as a replacement for nest protect. Install is fairly simple. However, it is not as feature packed as the nest. May also be a little too pricey but if you are looking to stay with the nest ecosystem, then this is likely your best option

I had to swap to this unit due to Nest Protect no longer available, Follow the instruction and setting up in first alert Resideo is very smooth. I was able to integrate with both Nest and Alexa. However, the quality of the unit (design, material, etc) is nowhere near the nest protect while it costs about the same. At least it uses the same bracket. Opt for a cheaper model unless you are trying to replace Nest Protect.

Replaced my Nest Protect with a First Alert and it works great, I didn't know that these devices expires in 10yrs and Nest Protect were discontinue. These work seamlessly on the Nest and Home app but it has its own app.

Very easy to install and fully compatible with the NEST device I had.

As advertised, this is a great direct replacement for an out-of-service Nest Protect, very easy to plug-and-play if you have the Nest Protect already installed. Once done the Google/Nest app recognizes it and integrates it seamlessly with any other Protects you have.

Easy to install. Tools me literally 10 minutes taking my time. The only downside is I miss the google nest smoke detector. I know this one replace the nest but I love the interface with nest. Beside that solid smoke detector

Solid replacement for your old Google Nest Protect (no longer made). Integrates well with other Google Nest Protects you may still have in your home (i.e. they will talk to each other should you have a smoke or carbon monoxide alert). Works with the Google Home app, after you download and install First Alert app first (2-step process). The voice alerts are a bit muffled compared to the Google Nest Protect, but still quality enough to hear and understand them. I would recommend this item to anyone looking for a plug and play replacement for your old Google Nest Protect.

Bought this because the original nest protect expired. Easy to set up and install with the adapter cable for prior nest protect and this first alert smoke detector. App easy to use and to add to google home.

Easy install and setup The first alert app is intuitive and easy to use

So far, so good. It has integrated with my google home setup and can communicate with my remaining nest devices. The two main downsides to this (which we can't do anything about if you want a replacement for a Nest smoke detector) is the appearance (this looks bland and boring) and that you need to use the First Alert app to setup the device and not google home.
