Your official Tegui and BTicino distributor
The largest stock of Tegui and BTicino materials and spare parts in Europe.
The BTicino 8/2 Digital Riser Interface (ref. 346150) is the component that allows up to 8 independent floors to be connected to the main 2-wire SCS bus in BTicino/Tegui 2-wire video door entry system installations. It acts as a vertical distributor between the floor bus and the building's main bus.
In buildings with several floors, each floor has its own secondary bus to which the apartment monitors are connected. The riser interface is the element that links this floor bus to the building's main bus, managing communication between the entrance panel and the indoor monitors on each floor.
