EXTERNAL DOOR STATIONS
PUSH-BUTTON PANELS
Mody series.
To plan a 4+1 video intercom system all the
button modules can be used, as well as the
back boxes, the protective shelters and the
decorative shields which have been described
on pages 11 to 19. Only the CCD camera
MD41 and the modules MD10, MD11 and
MD12 are different, in that they have not been
adapted for functioning with a reduced number
of wires (product MD41D, MD10ED, MD11ED
and MD12ED must be used).

tling stops (Larsen effect).
