MAIN FEATURES
Farfisa digital DUO System, developed with innovative technology,
allowstheinstallationofvideointercomsystemsupto200usersand20
door stations, drawing two non-polarized wires only, including the
powersupplytothesystem.Theveryreducednumberofconductors
with no coaxial cable allows a fast and simple videointercom and/or
intercominstallation,reducingmountingcosts.
