I have recently found out about the first alert talking smoke/co
detectors with onelink technology.
These detectors are interconnected. This means when one goes off, they
all go off. You can get hard wired or wireless.
What is unique about the first alert ones is you can assign a pre
programmed label such as kitchen, dining room or childs room.
When the smoke detector in the dining room is activated all smoke
detectors will go off announcing the location in trouble.
So if you are up stairs sleeping and there is carbon monoxide in the
basement your detector in your bedroom will announce there is carbon monoxide in the
basement. These detectors will also announce the location of a alarm with a low battery.
You can find them at amazon.com, just search for voice location or at
