The building is only 3 or 4 years old. The ghost call is very intermittent, it happens maybe once or twice a month. The same few home owners are complaining but all the boards on their floors and near floors have been changed and wires have been verified good. The floors are secured by card reader access and the security signals are sent to the Otis security interface board from the security company's relay boards. I'm not sure if it's happening on other floors because some of the units are not occupied all the time. There have not been any OCSS faults that I'm aware of but I will have to confirm on that one. The elevators are zoned to have one car at the bottom landing ( Lobby) and one around mid hoistway. They do not run without receiving a demand and the floors that are getting ghost calls are not near the parking landings. I have verified by their cameras that the car call does not light up when the car is called to the floor on a ghost call and it does seem to make a specific call to that floor and not just on its way to some other car or hall call. As far as I know, the Otis guy wasn't too pissed to lose it. He probably has too many buildings on his route already, he probably through a party that night!
