This version of the exchange has the features of the CD1803 exchange. The CD1803 MASTER/PR exchange allows realisation of complex systems for a group of buildings e.g. situated at a private residential development.

The MASTER/PR exchange should be used where a typical MASTER/SLAVE system is not enough, e.g. when there are several entrances to an estate. In such a situation each entrance is served by one MASTER/PR exchange. The MASTER/PR exchanges provide communication with an apartment, while other entrances are blocked for a while.
