B4-USI universal interface unit
The B4-USI is a universal communication unit and serves to connect SecuriFire 2000 to management systems and to actu-
ate external printers, pagers, ComBOX, telephone servers, etc. The link to management systems is line type and may be re-
dundant or single. The selection of operation mode of the interface pair parameters is performed by programming.
Further information about the B4-USI can be found in the technical description T 811 034.
