First Alert ZWave Combo

Hello, all.

A few weeks ago I purchased one of these and added it to my ST hub. Do I need to replace all of my smoke/CO detectors or is there a way to link them all together?

Thanks in advance!

As far as I know, the First Alert ZWave model does not include the “linking” feature that some of the non-ZWave models have.

So you you have to decide if you want (or legally need?) to have directly interconnected units, or if you have confidence you can either hear the units in other parts of your home (plus supplement with SmartThings SHM to turn on lights, alert phones, etc.).
