We have an elevator that is walk through on the first level and front opening on the other 7 floors. Our customer would like to make the elevator walk through on all 7 floors. This would require activating the rear opening on the 6 floors above the first level. Does anyone know if this can be programmed with the tool or will it require a software change from Schindler. There are no rear entrances now and the elevator was not originally designed to open the rear doors on any level other than the first floor.
