Video Distributor Unit
The Alpha Communications® 5556/004 video dis-
tributor unit is used with the 5601 and 5651 series
video-intercom systems. The 5556/004 is used when
the video signal from the lobby entry camera(s)
must be split (distributed) to several coaxial cables.
The 5556/004 gets its DC power from the system's
power supply. All 5556/004 connections are posi-
tive screw terminal and coax clamp connector type.
Each 5556/004 has four (4) video outputs. When
multiple 5556/004's are used, for systems requiring
more than four (4) outputs, multiple 5556/004 units
may be "daisy-chained" to provide outputs in mul-
tiples of four (4).
