WHAT IS IT?
We (a neighbor) has just moved into her Airstream, and has found a box installed 'up high' on the wall (near the ceiling in the hall); this box is beige in colour, has a dark brown button on the front (with no designation or description); and all night long this thing keeps her awake with a flashing WHITE light INSIDE the box.
DOES ANYONE KNOW WHAT THIS IS? It confused me because were it an LPG or Carbon Monoxide Detectors, they would be installed low at the floor area. She says this box has no name that she can see. Suggestions?
