About 328,000 smoke alarms sold nationwide and online by the Home Shopping Network — or as it now calls itself, HSN — are being recalled because the products can malfunction and fail to alert users of a fire, posing the risk of smoke inhalation or death, a federal safety agency said on Thursday.

If you have the recalled smoke alarms, contact Three61 for a free replacement. You will need to write “Recalled” on the alarm with a permanent marker, take a photo of the alarm and upload it to the company. Once the recalled alarm is registered, Three61 will send the replacement.

The Consumer Product Safety Commission shared on Thursday that almost 328,000 smoke alarms sold nationwide were being recalled because of a malfunction that could cause them to fail to alert fires.

The U.S. Consumer Product Safety Commission (CPSC) has announced a recall for certain smoke alarms. These smoke alarms may malfunction, meaning they won’t alert people to smoke — and, by consequence, to a potential fire — like they should.

Three61hass issued a recall for about 328,000 Samurai smoke alarms because they may fail to warn owners of a fire. The units were sold exclusively by HSN.
