Can anyone identify this "mystery alert shower device"? Ran across this yesterday inspecting a 4,200 SF vacant home that supposedly housed a group of drug dealers. This unit is on the wall of the master shower and has a alert type light in the center with 3 9V batteries. If I'd taken it off the wall I could tell you more about the wiring, if any, going to the unit. I could not identify any other "trip" or device that would be connected to this; the doorbell did not trigger it. No buttons on it. Any ideas? I told the buyer I did not have a clue. This was definitely a "party house" with lots of fixtures missing no no obvious grow ops rooms.
