Vertically adjustable folding top compartment floor on a vehicle with a folding or convertible top, which floor is connected by way of foldable side walls with the vehicle body. The novel specimen holder of the invention provides mechanical support for specimen support devices and as well as electrical contacts to the specimens or specimen support devices. This facilitates faster and easier drying of the wet, inner-stall facing side of the shower curtain due to improved airflow and the lower humidity of the room. Configuration instructions are sent from the management source to each of the one or more sets of security devices using an order determined by the identified configuration dependencies.
