Meet the new Nest Protect.

Fires were different 40 years ago. It used to take up to 30 minutes for a fire to take over a room. Now it can take less than five. Today's houses use different building materials; they have synthetic furnishings and open floor plans. And that can make fires more dangerous.

Fires were different 40 years ago. It used to take up to 30 minutes for a fire to take over a room. Now it can take less than five. Today's houses use different building materials; they have synthetic furnishings and open floor plans. And that can make fires more dangerous.

Now, more than ever, your smoke alarm should help you – and not just with a beep. It should give you the information that you need to get out safely. It should send a message to your phone. It should do more.

House fires have changed. And it’s time for your smoke alarm to catch up.

Four out of five firefighters in the USA would trust the Nest Protect smoke and carbon monoxide alarm to protect their homes. And today, we’re announcing the 2nd-generation Nest Protect. It’s been redesigned inside and out. And, once again, we’ve changed what a smoke alarm can be.

New Nest Protect. New features.

A new look and feel

Offices and industrial buildings often invest in a different kind of smoke alarm – one that can do more. So why should your office have more advanced fire-sensing technology than your house? Nest Protect is the first smoke alarm to bring a commercial-grade photoelectric sensor into the home. We call it the Split-Spectrum Sensor – it uses two wavelengths of light to spot different kinds of smoke, which helps it catch both fast- and slow-burning fires quickly.

That’s important for more than the obvious reason – that catching fires early is better. Because when other alarms notice danger, a piercing sound fills the kitchen as smoke rises from the burning bacon. You wave tea towels, search for a broom to hit the alarm with, then tear it off the ceiling. That’s not Nest.

With Nest Protect, fast detection means an earlier Heads-Up: a soft chime and voice to let you know that smoke levels are rising. It’s an early notification that you can silence easily. No need to panic. No noise. Just turn the heat down. Open a window. Make breakfast.

Part of that is thanks to a new smoke chamber, designed to help reduce false alarms. All photoelectric smoke alarms are susceptible to dust and insects, and any tiny particles that get into the smoke sensor over time. So the 2nd-generation Nest Protect has a stainless-steel screen with tiny hexagonal holes that let smoke in and keep everything else out. We’ve engineered this screen to have improved fluid dynamics and it has passed extensive air-flow testing.

And unlike smoke and CO alarms that need to be replaced after five or seven years, the new Nest Protect is built to last. It has a lifetime of up to 10 years, thanks to its new, long-lasting carbon monoxide sensor.

A new look and feel

At the heart of any smoke alarm is the sound – the actual alarm that warns you of danger. But if everything’s under control, you might not need that sound any more. So the new Nest Protect has App Silence.

With App Silence, you can silence an alarm from your phone using Bluetooth LE. No more climbing ladders or waving tea towels. Walk into the room and make sure that everything’s all right. Then open the notification on your phone – it will open the app, where you can press the Silence button. Tap and hold, and Nest Protect's alarm will stop.

A new look and feel

The London Fire Brigade recommends testing your smoke alarms once a week. This means climbing up a ladder and actually pushing the button on your alarm. But 9 out of 10 people don’t. And that leaves you at risk. So with the first Nest Protect, pushing the button tested every alarm in the house. And Nest continuously tested itself. Now we've made testing even easier. In addition to testing its sensors and batteries 400 times a day and showing you that they’re working at night with Nightly Promise, the 2nd-generation Nest Protect lets you test all your alarms manually from your phone. We call it Safety Check-Up. With it, you can test the sensors, power, Wi-Fi connection, siren and speaker on every Nest Protect in your home with just one tap.

And then we took it one step further. To make sure that you hear it when something goes wrong, the 2nd-generation Nest Protect automatically tests its speaker and siren once a month with a quiet one-second chime. It’s called Sound Check. And it’s thoughtful too – Sound Check will do its best to test its audio when nobody’s at home to hear it.

Nest Protect is available now. Order it from nest.com/uk/ for £89.
