2280 BUS INTERFACE

The Art.2280 enables the connection of either the Videx Telephone

Interface (Art.380) or the Videx apartment station (Art.500MM) to the

VX2200 system.

Using this device it is possible to carry out all the functions available on

the VX2200. For example, answer a call from the door panel (and if

necessary open the door), call the concierge (if present on the system)

and intercommunicate with another user (via concierge).

The system draws power directly from the “2 wire” Bus (Less than 0.8mA)

and from either the 380 or the apartment station power supply (12Vdc). It

includes an 8 way Dip-switch for programming the device with the phone

ID address and a trimmer control for the audio volume towards the door

panel.

It is possible to connect up to 180 devices on the same “2 wire” Bus, with the possibility to use the same

address for a maximum of 3 devices (for those applications that require more than one unit in the same

apartment). Use VX2280 version with 900 series and VX2280-1 with 3000 series.
