Google S3003LWEF Nest Protect Smart Hardwired Powered Smoke and Carbon Monoxide (CO) Alarm. The smoke alarm that thinks, speaks and alerts your phone. Nest Protect has been redesigned from the inside out. It has a Split‑Spectrum Sensor, tests itself automatically and lasts up to a decade. It’s also the first home alarm you can hush from your phone without any extra hardware required. And it tells you what’s wrong and can even alert your phone, letting you know the level of danger and where it's present in your home.

Features:
App Silence - Silence alarms with your phone, not your tea towel. If everything's under control and there's only a little smoke, silence the alarm from the Nest App.
Phone Alerts - Everyone in your family can know whats going on, from anywhere. When something's wrong, Nest Protect sends everyone an alert in case no one's at home.
No Chirps - Tired of being woken up at 2 am by your smoke alarm? Long before it has to chirp, Nest Protect tells you that it's batteries are running low with a message on your phone.
Safety Check Up - Test all your alarms with a tap. And once the test is finished, you'll receive a full report.
Family Accounts - Everyone in the family can have their own Nest account. No more sharing a password. You can all use your phones to silence and tet alarms. And you'll all receive alerts on your phones if something's wrong at home.
Sees both fast and slow-burning fires. - The foam and particle board in much of today’s furniture make fires burn faster. Technology should keep up. The Split‑Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smouldering fires.
10-year CO sensor. - Carbon monoxide is poisonous, but you can't see it or smell it. That’s why Nest Protect has a long-lasting carbon monoxide sensor that keeps working for up to a decade.
Lights your way - If you need a glass of milk in the middle of the night, Nest Protect lights up as you walk underneath it. Pathlight is one of our customers' favourite features, so we've made it better and brighter.
Tests itself - you're supposed to test smoke alarms monthly. But most people Don't. So Nest Protect checks its batteries and sensors over 400 times a day. And it’s the first alarm that uses Sound Check to quietly test its speaker and siren once a month.
Steam is not smoke - Has your alarm ever yelled at you for having a shower? Nest Protect comes with Steam Check. It uses custom algorithms and a humidity sensor to look for steam so that you can enjoy a nice, quiet shower.
