VDS GUARD UNIT ( Ref. 2536 )
The VDS system can be completed with a desktop or wall-mounted CENTRAL GUARD UNIT.
The VDS Central Guard Unit offers a «filter» between a building’s visitors
and its residents. This allows communication between the guard unit and the
residences, as well as the reception of calls made from entry panels to the
residences, so that they can then be transferred by the guard unit to the
residence called or to an alternative residence.
The guard unit has 3 operational modes: Day, Automatic and Night.
To install a VDS guard unit in a system with entry panels you require a «VDS guard unit connection module» Ref. 2492.
This module allows the user select the active devices and establish communication between them:
- Guard Unit < -- > Residential Terminals:
- Guard Unit < -- > Panel.
- Panels < -- > Residential Terminals:
In systems without an entry panel the installation of the guard unit does not require a connection module.
For more details see «Section II. Wiring Diagrams ».
