These are easy to wire up and mount. The interconnection works perfectly and they are loud enough to provide early warning ro everyone in the house.

Did not last six months

Would Not Recommend

I purchased six of these, in February 2026. I paid to have five of them installed. The end of July 2026 I came home to one beeping. we changed the battery thinking maybe we had a lemon battery. That did not stop the beeping. So luckily, I had a spare unit and we replaced it. That solved the problem. Tonight, the end of August I came home and another one was beeping. These are supposed to last years; not weeks.

Poor Batteries

Would Not Recommend

We are so disappointed in these smoke alarms!!! The day we installed them the batteries begin to sound off for being low. We are now weeks into these things and it's still more batteries going low, then we have to determine which ones, we change batteries and then they continue to beep !!! Horrible

Product works great. They talk to each other throughout the house so all rooms and everyone is aware of there’s a problem.

Must Hardwire

Would Recommend

This set does not come with the adapters to match pre existing smoke detectors like the individual ones do. They have to be spliced into the wiring or you have to buy the adapters which only comes in a 12 pack. I needed 5 to update all the ones in my house that were 20+ years old. I'm sure they'll be fine when I'm actually able to install them.
