First Alert Onelink Safe & Sound Smoke + Carbon Monoxide Alarm REVIEW


The Onelink Safe & Sound Smart Smoke + Carbon Monoxide Alarm is an Apple HomeKit enabled device that is also a speaker with Amazon Alexa integrated. This is the first-ever smart smoke and carbon monoxide alarm with a built-in Alexa Voice Services. In addition to having a strong safety alarm integrated, the Safe & Sound can also play music, audiobooks, read you news, and even control smart home devices. Because the alarm is installed on the ceiling, the speaker will fill any room with 360-degree audio. The alarm has an advanced microphone with noise-canceling technology which allows the Safe & Sound to hear you from any direction. The alarm is powered by First Alert’s technology for smoke and carbon monoxide detection and will warn you of any danger in your home with an 85-decibel alarm and through your smartphone. The Safe & Sound currently works with Apple HomeKit, the Apple Home App, and will be compatible with AirPlay 2 later in 2018.

  • Works with Apple HomeKit
  • Embedded Alexa Voice Services for Convenience and Control
  • Hardwired Alarm with Easy Setup and Installation
  • Mobile Connectivity Through the Onelink Home App
  • Airplay 2 Compatibility Available Later this Year


The Onelink Safe & Sound came in a beautiful Onelink branded box. Normally, I don’t express beauty when it comes to product packaging, but for me, the branding and box design was eye-catching and memorable. There is a clear image of the device on the front with the Apple HomeKit and Amazon Alexa logos on the front. The box also makes it very clear that the device is a 3-in-1 product (smoke & carbon monoxide alarm, home speaker, and Alexa-enabled device). Aside from that, the packaging is pretty straightforward. It has an ample amount of information included, but not so much that it distracts any potential buyers from what the device is all about.


The Onelink Safe & Sound alarm is a very nice addition to any smart home. It’s an easy installation process especially if you already have an electrical tie-in. The speaker is a really interesting option for this device and in my opinion, makes it complete. I love that it has such an easy set-up process and that it’s one of those devices that you can set-up and leave it to do its job. I can recommend this alarm to anyone who wants to step up their smoke and carbon monoxide detector equipment.
