Smartphone alerts You should always be in the know, so the Nest Protect has a Heads-Up early warning function. It sends you a message on your smartphone or tablet it detects smoke, or if carbon monoxide levels are rising, so you can take action. The alarm has yellow lighting when it detects danger, and speaks with a human voice to let you know what's going on. If you have more than one Nest Protect, they will all speak at once.
