VDS Switcher (Ref.2450)
In VDS systems with 2 video door entry system access points a «VDS Switcher ref.2450» is required.
Its aim is to select the video signal of the panel from which the call has been made. This selection is by way of a signal
(negative) sent from this panel through a «S» wire (see wiring diagrams).
It is not necessary in systems in which one of the accesses is audio only.
In systems with a guard unit, this switcher is substituted for a «VDS Guard Unit Connection Module» Ref. 2492.
Panel Connector 1: «S, +, L, V, M» connection
wires from Panel 1.

The VDS switcher has 2 status options:
- Standby: switcher output connected to the Panel 2 input.
If Panel 2 is activated (after a call from a residence or auto-start), Panel 2’s audio + video signals will be sent to the
switcher output.
- Active: switcher output connected to the Panel 1 input.
When Panel 1 is activated (after a call from a residence or auto-start) a “negative” signal is sent via the «S» wire
which activates the switcher, connecting the switcher output to the Panel 1 input.
The switcher returns to standby mode when Panel 1 is deactivated (end of communication).
