The City Line outdoor panels are made in 9 differents series. All of them are the same wide but
each serie is a different height.

Each one of the series includes different panel models, depending of their size, if they have single
or double pushbuttons, pushbuttons only, windows ( where the telecamera or any other available
complement is allocated ). So you can place, horizontally, as many panels as you need,
combination are practically unlimited.
