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. No more annoying alarms Fed up with steam in the kitchen setting off your smoke detector? The Nest Protect Alarm knows the difference between steam and an emergency situation, so you can expect fewer false alarms. If you've burnt the toast and set off the alarm, you can use the app to silence the alarm – there'll be no more wafting a tea towel at your smoke detector. The alarm is wireless, which means you can place it wherever you need it.
