First Alert OneLink Safe and Sound Smoke Detector blogger eview 

2:06 The red wire is actually for Interconnecting smoke alarms together so that if one alarm goes off, then they all go off

*I bought this to keep in my garage **do7.pl/First** since I have a FOB in my car to start and turn off. It’s very easy to forget to turn your car off in the garage and there has been reports of carbon dioxide poisoning from people stepping out of their cars thinking they turned them off and go in the House only to be poisoned by carbon monoxide poisoning. I like it as a safety measure, as we all have stressed days and aren’t thinking things through.*

Why not show a "realistic" test of smoke and carbon monoxide. You cover the extras, but not the reason why one would buy this smoke/carbon monoxide detector because noting indicates it does its primary job with notifications to the phone..

😮 a smoke alarm that can play music? awesome

Can I see and hear the full testing cycle on the Safe & Sound?

Ah, so there are two versions of the same thing. 1. First Alert OneLink Safe & Sound Carbon Monoxide Smoke Detector (with Alexa and smart speaker with nightlight) 2. 1. First Alert OneLink Safe & Sound Carbon Monoxide Smoke Detector (without Alexa and smart speaker without nightlight)

Did you ever get them to “pair” together to use them as surround sound speakers?

Could u link it with pandora?
