CVP-1 switch of video signal

CVP-1 switch is designed for CD-2502 door phone in video version in the system with the main entrance. Thanks to the switch, the image from the camera placed in the panel from which the calling is (panel at the main entrance or a panel at the entrance to the staircase) is displayed on the monitor screen. In the switch, there are inputs of the vision signal (C1+, C1-) for the signal from the main entrance and (C2+, C2-) for the signal from the subordinate one, and two outputs of the signal (X+, X- and Y1, Y2).

The switch may be powered from an electronic cassette or its own adapter. CVP-1 switch should be installed at each subordinate entrance, as close to the electronic cassette as it is possible. The switch has configuration jumpers enabling to set strengthening and vision frequency correction and line impedance.
