DM2444
. In digital installations DUO the line
distributor DM2444 allows to distribute the video
signal coming from several external door
stations to the internal videointercoms
according to the addresses programmed in
the address intervals of the output lines; audio
and calling signals are on the contrary distributed
to all the devices without taking care of their
address.
Warning. The device do not allows multiple
calls and conversations. A call originated
from any external door station makes busy all
the other input and output lines until the end
of the conversation.
