Hi All,
Browsing through the various threads and can see that there is some confusion here.
The overall essence of the Alpha Range as a whole is to reduce the wiring requirements and soldering needs of the layout as a whole as, lets be honest, this is were most faults occur on a layout.
The Alpha Box is in effect a universal booster with one of its intentions of allowing smaller DCC systems such as the Hornby Elite, Bachmann ezy Command, and other similar systems to be converted into a 5amp system without having to get a whole new system.
The Alpha box is also fitted with a Circuit Breaker and On/Off button to turn track power off without having to turn the whole system off.
The Alpha Box can also act as a Booster for a Accessory bus taking amperage off the main DCC system or as and additional booster to any layout and interface for the Alpha main unit for controlling DCC Accessory items on the layout.
The Main Alpha unit is a Digital encoder that takes any manual switch action and converts it into a DCC command which is sent via the DCC system (or Alpha Box) down the DCC track bus to the relevant accessory decoders on the layout. This means that you can have a conventional switch panel with all the wiring contained in the panel and not having wires traversing all over the layout like a spiders web because they just connect into the terminals on the Main Alpha Unit. This in turn will connect into the cab bus of the NCE and Roco systems and the Alpha Box. This saves wiring hassle and make fault finding simpler and more time to run trains.
The Alpha Switch packs follow on with the wiring saving theme where the switches have LEDs built into them so when pressed it lights up and its wired twin turns off. The switches connect via a plug harness into a central PCB where no soldering is required. On the other side of the PCB are outputs to feed out to the relevant Accessory decoders (switch-D version) or Stall motors (switch-A version) or you can feed it it directly into the Alpha Main unit.
Granted this range is quite extensive and a bit bewildering and with note to the current manual this will soon be replaced with a updated version which will help stream line things.
The Alpha Central is inspired by the Marklin Central of old and is in effect a pre-finished control panel which contains the components of the Alpha Main and switch units which can connect directly into the cab bus of the NCE or Roco systems and the Alpha Box.
There will be another major addition to the Alpha range coming soon at the Alexandra Palace show this coming weekend along with Several other Major Pieces of News which will be of great interest to you all I am sure.
Feel free to ask more questions as I am not sure if I covered everything here.
