Nest Labs is recalling 440,000 smoke alarms to fix a feature that could prevent the alarm from sounding immediately.

The Nest Protect Smoke + CO alarms allow users to temporarily silence some alerts by waving their arm near the unit. The company is offering an electronic update to disable this feature. It has not received any reports of incidents, injuries or property damage.

The high-tech home monitoring device company, which was acquired this year by Google, halted all new sales of the alarms last month after recognizing the problem.

The U.S. Consumer Product Safety Commission said Wednesday that the recall applies to all of the Nest Protect Smoke + CO alarms.

Nest says the device must be connected to the Internet and linked to an account for an automatic update.
