Kidde P12040 smoke detector problem

Hi All, has anyone had any issues with the Kidde P12040 smoke detector,reason for the question, my neighbor has a house built in 2011, vacant most of the time,something in the detector apparently shorted and charred the ceiling around it, thoughts on what could have caused this.

Anything for simple circuit failure, to a loose connection, maybe even a local electrical transient from something like a nearby lightning strike. It's a hardwired 120V smoke alarm. Replace it, make sure the 120V connections are solid, and move on. Check the others that are the same age in the same location.
