I have first alert zwave zcombo sensors (smoke/co) connected to homeseer. During an alarm all connected lights turn on and I am sent text messages.
You can use almost any zwave controller and zwave switches/lamp module/bulbs to achieve the same thing, though I recommend a controller that doesn't depend on the internet (aka smartthings, wink, nest, alexa)
For the price of 2 nest protects (@ $240) you can get a homeseer zee2 and two first alert zcombos. ($230+shipping). Then you have a lot more options and flexibility.
You could save some money on the controller with a hubitat elevation for $75. It has more radios but it isnt as flexible or as powerful as the Pi3 powered Zee2.

I have no idea about heal tolerances, but I found one that wirelessly connects to others, so if one goes off they all go off. I hooked up 3 of these in my house that doesn't have any hardwired smoke detectors.

EDIT: Alternatively, you could get one of these which connects to smartthings hub, so if it goes off you could get notifications on your phone. I actually bought 3 of these as well:
