BASIC VDS SYSTEM DEVICES
In addition to the entry panels and guard units, the VDS system requires a number of basic devices to complete the
system and ensure its correct operation.
The functions of each of these devices is detailed below:
DEVICE
VDS Switcher
(Ref. 2450)
FUNCTION
Necessary in VDS systems with 2 video door entry access
points (this is not necessary in systems where one of the
access points is audio only).
Its aim is to select the video signal of the panel from which
the call has been made.
‘Video Distributors’ are required at all system points where
there is video signal bifurcation: branch distribution,
residence distribution per floor, etc.
VDS Power Supplies. Provide the system with power.
Depending on the system (number of monitors/
telephones installed, type of lock release used, distance,
etc.), the necessary voltage may vary by model and number
of power supplies.
