Nest Is Recalling Over 400k Protect Smoke Alarms

Illustration for article titled Nest Is Recalling Over 400k Protect Smoke Alarms

A little more than a month after Nest announced it would halt the sale of its Protect smoke and CO alarm, the company has announced the official recall of every alarm sold thusfar. A report filed on the US Consumer Product Safety Commission website announced the recall.

The safety issue is the same one that triggered Nest to stop selling new Protects in April: Nest Wave, an algorithm that allows users to "wave to hush" some alarms and tests. It was one of the coolest design details of Protect, sadly—the fact that, rather than getting up on a chair and hitting your smoke alarm with a broom to turn off a false alarm, you could simply wave at it and its embedded motion sensor would silence the noise.

But that awesome feature is also potentially dangerous. Let's say there's a real fire in your kitchen: As you're rushing to leave, Protect could theoretically interpret your movement as a "hush," and silence the alarm. In other words, functionality designed to stop false alarms could actually shut off a real, life-saving alarm.


So far, Nest hasn't received any reports of this scenario actually occurring—no one has been hurt, and no damage has been inflicted on homes because of the mistake. Still, the company is playing it safe, recalling all of the Protects sold so far. If you prefer to keep your system, though, there's an easy fix: Nest has already pushed out a software update that disables the Wave algorithm for existing users (here's how to make sure it works).

It seems that Protect's cleverest functionality is also its achilles' heel. Learn more about how to return or update your Protect here.

Update: Nest has passed along a statement about today's news: "The CPSC press release issued today refers to the same corrective action referenced in our April Safety Notice from the CEO, and in fact, we'll be bringing Nest Protect back on the market soon. We have been working with CPSC and they have approved our corrective action as previously announced."
