    So happy to have this reassurance that my house is protected by this unit even when I am away from my house. I love the idea that professionals can assist me with monitoring my home. It really gives me peace of mind.

    At first, I was looking to get wired and that was actually what I got at first. I’m very glad I kept it all because it connected to my smart system easily. I am also very happy with the photosensor technology.

    Got these to work with my Ring alarm system. But the first few would not connect to the system. Best buy replaced them and the replacement works fine. I have other First alert products and they work well.

    Bought this because it "works with Ring" as Ring does not have a smoke detector for their alarm system. I like the fact that it is made by a reputable company that has been putting out safety products for many years and knows what they're doing.

    This is an excellent product. I love that it works with the Ring products and Ring monitoring. These are giving me piece of mind that my house is being monitored for fire during times I am away from home for long periods of time, especially since we don't have fire hydrants near us.

    The main thing that drew me to this was that it said it works with Ring security system. It seems to only work with Ring if you purchase another accessory from them. While I decided not to purchase the extra piece I know First Alert is a great name and believe me you will definitely hear it if it goes off anytime during the day

    Although this is not a Ring manufacture it is designed to work directly with the Ring system. If you have the professional monitoring the emergencies are forwarded to the fire or emergency.
