The First Alert Onelink Safe and Sound detector features a fairly large oval case made of plastic, with the front side divided into multiple inner sections by narrow plastic bands, the device mostly being covered by lots of puncture holes the middle section is slightly elevated. Surrounding the top area there’s a metallic ring while towards the bottom, the case gets significantly slimmer and it features narrow holes all around to
allow the smoke to enter the inner chamber. It’s hard not to see the striking similarities with the Nest Protect, which is also covered by lots of small holes on the front side, as well as the overall shape of the smoke detector and the LED light which shines from the circular middle section on both smoke detectors it’s clear that all smart smoke and CO detectors follow the same design pattern, so it’s not surprise that both the First Alert Onelink and Nest Protect look so similar: it seems that developers either think that this is the most ergonomic design or are simply afraid to try something new. Similarly to the Nest Protect 2nd Generation, the Safe and Sound also has a NightLight which can be adjusted in terms of intensity or colour depending on the time of day, but it cannot be set to turn on only during the night while Nest does allow it. The Onelink Safe and Sound alarm is slightly larger than your average non smart smoke detector it measures 6. 8 x 6. 8 x 2. 26 inches and weighs 1. 5 lbs, but, because of its flush mount aspect it does give some aesthetic value to the room. The main attraction is the speaker, which is located on the small middle section which will work in most cases along with the LED ring for example, when using Alexa, the LED will be solid blue when Alexa is processing your request and will become half red when the microphone is muted. I can’t really say that the speaker is among the best, but the fact that you position the device on the ceiling definitely
makes it sound better than the regular Alexa devices.

Of all the smoke alarms we reviewed, this Kidde model fared the worst in our detection tests. Smoke must be very dense and concentrated for the alarm to sound. This
underscores the need for multiple smoke detectors in several places in your home.

best parts of this smart smoke detector is that it comes with a 10 year warranty, which is just as long as the device's sensor lifetime. Other smart smoke alarms have more traditional warranties that last only a couple years. This smoke detector also has a carbon monoxide sensor to further improve the safety of your home. If it detects a problem, you'll get three alerts: a loud tone, voice alerts and a mobile notification to help you respond to the situation accordingly. We found this unit easy to set up and connect to Wi Fi. First Alert has also created a standalone mobile app for this smoke detector that lets you test, control and monitor the battery.
