Years ago I was doing a service on a duplex when the bldg. manager caught me in the basement and said, "This elevator on the left is not responding again, happens every other day" Oh really? "Yeah" I thought to myself... "I was here on a call back the other day, but it was ROA." So it turns out the safe string is open. OK. The cars at the 3rd landing, but no DZ. Huh. Up to 3, pick the doors, roll open the car doors, and there they are! The two office love bugs having a time in the cab. They had discovered the stop switch wasn't alarmed, and they could hanky panky for a spell and simply push the switch back in and away they'd go. How could they possibly get caught? I don't think they heard the doors open, but I know they heard them close! Consequently, both alarm bells were wired back in to the stop switch to avoid future nuisance calls.
