hafele R2 Dialock Instrucciones De Montaje Y De Servicio página 24

The connection between the reader and the control units can be made
using a standard 4-core cable. We recommend using a standard electrical
cable J-Y(St) Y 2 x 2 x 0.8 with a maximum length of 50 metres LEGIC /
35 metres Tagit ISO.
When installing several wall terminals, ensure that the distance between
the reader units is at least 25 cm (fig. 7). If the distance is too low, the RF
fields may overlap. This may cause that transponder media are no longer
reliably detected.
