Easy setup with ring system

Reviewed in the United States on January 6, 2025
Purchased a few of these for the garage and basement. I like the fact that I get an alert on my phone via ring app if one of these goes off. And the face that it’s smoke and CO is a plus. Setup was very easy and works great. Know you have to replace these every now and then especially in a garage th... Read more

Works with ring and battery operated

Reviewed in the United States on February 11, 2025
I was looking for smoke alarm which is battery operated since I don’t have a hard wire available. I want it to work with ring so that it can integrate with a central monitoring system to satisfy our insurance company’s new requirement.

This one fits the bill. It’s affordable, and it to...

Easy Setup, doesn't falsely go off.

Reviewed in the United States on February 12, 2025
It works great. I had an easy setup process. I bought a Used new item, and it's never falsely gone off. Thankfully, I've had no Fire, so I haven't gotten the chance to see if the product does work correctly.

My only complaint is that First Alert hasn't kept a consistent mount size

Reviewed in the United States on December 11, 2024
A First Alert smoke and carbon monoxide detector - that integrates in with Ring as soon as it's powered up - pop into the Ring app, accept the device, and configure where it is. Easy-peasy, lemon squeeze. It's nice to be able to peek into the house and see that the alarm is quiet.
