VX2200 Entrance Switchers

A range of VX2200 system entrance switching devices for both audio and video systems:

VX123A / VX123V – 4 door audio and video switching PCB’s respectively.  Both versions contain 4 inputs for entrance panel common connections, an output to telephones and an input to link multiple PCB’s together for systems that require more than 4 entrances.  Voltage to each entrance panel (12Vdc) is fused and indicated by an LED.  The VX123V contains an active LED for all entrance inputs to display when a certain entrance is in use.

2206N – The 2206N is a powerful device which allows the system to be expanded up to 998 apartments. There are two applications in which this unit can be used. The first application is a system with both main entrances and sub entrances/blocks (Main entrances call all apartments on a system and sub/block entrances only call the apartments in their own block). In this application, one 2206N would be required for each block. The second application is a single level system with up to 10 entrances whereby all entrances need to call all apartments. In this application, a 2206N would be required for every 180 apartments and could be used to expand the system up to 998 apartments(i.e. 500 apartments would require a minimum of 3x2206N).
