This gives checking your smoke alarm a wholly different meaning. Kidde United Technologies left a 'yellow cap' on while the alarms were being manufactured.

The cap covers one of two sensors and could leave you at risk of not knowing there's a fire in your home. The yellow cap hinders the alarms capability to 'smell' smoke.

The type of model involved is the Dual Sensor Smoke Alarm. If you have one, remove the alarm from it's mounted position and look through the openings on the sides of the alarm for the yellow cap.
