VIDEO DOOR PHONE RISERS CONNECTION
This chapter shows the different ways of connecting a riser with at least one video door phone regardless of
whether it is derived from a column power supply unit, a column distributor or a column interface.
Special decoders and door phone connections are similar, but special decoders must be installed
at the end of a branch. On the decoder In/out connection can not be performed.
