Miproms have field programmable hall call door times,lobby time, car call times etc,etc. Does this 3 car group have serial communication, or does it have a common panel? If it has a common panel only 2 cars have hall calls and the 3rd car is a slave. The Slave car is the last controller. If this is the case everything is operating as it should. It is not the best 3 car system.
