First Alert's All-in-One Smoke Detector, Carbon Monoxide Detector, and Speaker Now Supports AirPlay 2

Tuesday February 18, 2020 6:54 AM PST by Joe Rossignol

First Alert today announced that its Onelink Safe & Sound, an all-in-one smoke detector, carbon monoxide detector, and speaker system, now supports AirPlay 2 for multi-room audio playback.

AirPlay‌ 2 enables multi-room audio playback with other ‌AirPlay‌ 2 devices, such as the HomePod, Apple TV, and select speakers from Sonos, Bose, Bowers & Wilkins, and others. ‌Users can select where the music is playing in Control Center on an iOS device or ask Siri to play music in a specific room or the whole home.


Introduced at CES 2018, the Onelink Safe & Sound distinguishes itself from a traditional smoke detector with a built-in speaker and noice-canceling microphones, plus support for Amazon Alexa.

With existing HomeKit support, homeowners can add the Onelink Safe & Sound to the Home app and receive push notifications if smoke or carbon monoxide are detected. HomeKit also allows the detector and music playback to be controlled with Siri using an iPhone, iPad, Apple Watch, Apple TV, or HomePod.

Regularly priced at $249.99, the Onelink Safe & Sound is currently on sale for $178.25 on Amazon in the United States.

These are not 3 separate devices. This is one device, and we are calling it iPhone. Today Apple is going to reinvent the phone.

I like how in the picture they have it installed on the ceiling. If the carbon monoxide alarm goes off, you’re dead. I don’t understand why companies insist on putting smoke alarms and carbon monoxide alarms in one unit.

Because actual science says it's not a problem. First, look at the periodic table. CO is lighter than O2 and N2, since C is lighter than both N and O. So if anything, CO accumulates near the ceiling, not the floor.

The actual density of CO is 1.14 kg/m3 whereas air is 1.18 kg/m3 at room temperature.

In actuality, the density of CO is close enough to air that natural air currents cause a fairly even distribution anyway. In fact, O2 has a density of 1.33 kg/m3 and N2 has a density of 1.17 kg/m3, yet they don't stratify and cause us to asphyxiate when we stand on a ladder. Therefore, there is no need for a specific height to mount CO detectors.

For that price, you'd be better off getting a dumb smoke/CO detector and a HomePod (on sale).
That is waaaay too much for a device that should be replaced every 10 years. (Some recommend 7 years.)
Really...any AirPlay 2 speaker will sound better than this.
No. I haven't heard one of these. It's just common sense.
