First Alert Onelink Safe and Sound Smart Smoke Carbon Monoxide Alarm with Speaker & Alexa
Alexa

Can I play music to other Alexa devices or my Everywhere group with Safe & Sound?

Not at this time. Alexa and Safe & Sounds keep getting smarter over time, so you can look forward to more audio capabilities in the future.

Does the Onelink Safe & Sound require rewiring or professional installation?

The Onelink Safe & Sound is meant for DIY installation. Just remove your current alarm and bracket, and install Safe & Sound. Easy adapter plugs are included, so you don't have to rewire to install the alarm.

Once the Safe & Sound unit is wired into my ceiling, what are the next steps?

Once the alarm is installed, the unit will walk you through setup and Alexa integration with Onelink Home app. If you have more than one Safe & Sound, set each one up though the app as you install the units, before moving on to the next one.

How does the Safe & Sound nightlight feature work?

When set on autobrightness, the LED lights glow to light your route in the dark, and get brighter in the day, to ensure visibility in an emergency. You can turn off autobrightness, or adjust brightness and usage through the Onelink app.

Do the LED lights on Safe & Sound also indicate power?

The LED lights also indicate AC power is being received. When you disable the nighlight, 2 LEDs will glow green on the Onelink alarm, letting you know that you have AC power. If the LED is off, your alarm is running with battery backup.

Product Description

Protect your home and your family, and enjoy a hands free voice controlled speaker with a great audio experience at the same time. First Alert's Onelink Safe & Sound is a smart smoke and carbon monoxide alarm with Alexa Voice Services enabled. Ask Safe & Sound to play music or audiobooks, read you the news, control smart home devices, and more.

The light is ALWAYS ON!
2 Stars
The light is ALWAYS ON!
I like that this device is easily integrated into HomeKit, which means I can adjust the light and disable alarms right from my Apple Watch if the oven happens to set it off while cooking in the kitchen.For the price, I wasn't expecting much as far as sound quality goes, but it is advertised as a "Premium Home Speaker" and that is NOT my experience with this product. At the initial set-up, the recorded voice instruction sounded like it was playing on a speaker that was blown. After completing the set-up process, I tested the audio and sure enough anything played through this speaker above 35% volume sounds absolutely terrible. I plan to request a replacement to see if maybe I just got a bad unit.***UPDATE***I managed to get a low-light photo of the night-light that cannot be fully turned off and uploaded it as this revised review. Turns out the speaker on the one I initially had was definitely not working correctly. I ordered a second unit and returned the first one. The new one sounds much better. However, I cannot add any stars to my original review, since after installing it I found that the LED light never fully turns off. It can be a distraction at night when I need complete darkness to fall asleep. Thankfully this works as an AirPlay 2 Speaker and I've started to play white noise to it to help drown out the sounds of the city. So, I can justify continuing to use it at the price I paid (it was discounted by $100), but if I'd paid the full $270 I would not be keeping it. The always-on light would be a total deal-breaker for me at that price point.Updated***I removed one more star from my rating. This thing will randomly talk at you to let you know it’s disconnected from the WiFi for a brief moment. It’s really creepy when it happens in a quiet and mostly empty house and I wish there was a way to disable the WiFi disconnect voice alert.
