STANDARD VIDEO DOOR ENTRY SYSTEM WIRING DIAGRAM VERSIONS WITH COAX CABLE
VERSION 21
Wiring diagram of video distributor type 5556/004 for several cable risers.
The video connection must be made using a RG59 type cable or one similar with an impedance of 75 Ohm.
75 Ohm resistors (supplied) must be wired across video outputs V1-V2-V3-V4. These resistors must be wired to the output terminals not
used or terminals V2-M on the last riser monitor. A 75 Ohm resistor must also be wired to the “V” voltage-free terminal on the last distribu-
tor.
N.B.
Video distributor type 5556/004 is equipped with trimmer P1 which simultaneously adjusts the video signal gain at all the outputs.
This trimmer is factory-set to 1.
