I have two buildings with older Tac 50 04s. One is a duplex, the other is a triplex. I was working on a car at the duplex building today, had it on inspection, the other car in service at the same landing and it would not answer a hall call at that landing. After a few minutes it took off for another hall call and came back for the one where I was at. The triplex building is the same senario, and 1 car serves 1 more landing and it frequently will latch and cancel a hall at that landing (in normal operation ofcourse). The controls are the 18 bit processors. Does anyone know if Thyssen has a software fix for this or something?
