The smoke alarms were recalled for potentially being faulty.

Kidde recalled close to 500,000 'Dual Sensor Smoke Alarms' on Wednesday, March 21. The detectors were recalled for the risk to alert people of a fire. Meaning, they may not actually detect the smoke.

The specific models recalled were PI2010 and PI9010.

The reason the alarms may not detect smoke is that a yellow cap was left on the models during the manufacturing process. This cap blocks the sensors that detect the smoke. Therefore, people may not know when there is smoke or a fire in their home.

People who own these smoke alarms are urged to take them off the wall or ceiling and inspect for a yellow cap. Do not take apart the alarm, and do not attempt to remove the yellow cap if it is found. The Consumer Product Safety Commission says to contact Kidde immediately if the cap is found for a free replacement smoke alarm. You can call Kidde toll free at (833)-551-7739.

According to the recall from the United States Consumer Product Safety Commission, roughly 452,000 were sold in the United States. About 40,000 were sold in Canada.
