Smoke + CO alarms recalled for failure to sound

About 440,000 Nest Protect Smoke + CO alarms are being recalled because activity near them at the time of a fire can prevent the alarm from sounding.

The recall includes all Nest Protect Smoke + CO alarms, which were sold for about $130 at Best Buy, Home Depot and other retailers and online at and between November 15, 2013 and April 3, 2014.

The alarms are unique because they can be controlled by a computer or smartphone over a wireless network.  Their “Nest Wave” feature lets you temporarily silence the alarm or a test of the alarm by vigorously waving your arm near the sounding alarm unit.

That Nest Wave feature, however, is at the center of a recall of the units according to the Consumer Product Safety Commission.  Movement or activity near the units at the time of an actual fire could prevent them from sounding.

The Nest Wave feature is set to “on” at the factory, and must be manually disabled by the consumer.  Connecting the device to a wireless network and linking it to a Nest account allows the device to receive an automatic repair.

“The repair is an automatic electronic update that disables the Nest Wave feature and is delivered automatically to devices connected wirelessly to the Internet and linked to a Nest account,” said a notice on the CPSC website.
