Nest Labs Recalls to Repair Nest Protect Smoke + CO Alarms Due to Failure to Sound Alert

This recall includes all Nest Protect Smoke + CO alarms. The alarms are made of black or white plastic and are about 5.25 inches square with rounded corners and about 1.5 inches deep. The word "nest" is on a large button on the face of the alarm. Consumers can enable the alarms to be controlled by a computer or a smartphone over a wireless network. The alarms have a Nest Wave feature, which allows users to temporarily silence some alerts or cancel a manual test by vigorously waving an arm near the unit that triggered the alarm. Nest Protect Smoke + CO alarms came from the factory with the Nest Wave feature enabled and with the slider button in the "On" position in Nest Protect Settings.
