ANTILOCALE
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).
AMPLIFIED DOOR STATIONS
MD10ED. Module without call buttons, with
front plate in anodized aluminium, amplified
door speaker in two channels and control of
volume of "receiver".
MD11ED. Module with 1 call button.
MD12ED. Module with 2 call buttons.
Testing and adjustments
Adjustments are carried out in the factory; should
any be necessary they can be re-adjusted from
the outside with a screwdriver with the trimmers
identified by the words “antilocale” and “vol-
ume”(
).
Volume adjustment
To increase the volume from the amplifier in the
transmission mode, turn the trimmer “
” in a
clockwise direction.
Antilocale adjustment
In case of "feedback" (Larsen effect) in the
external unit it is necessary to operate as fol-
low:
- make the call from the door station and lift the
handset of an intercom;
- adjust the trimmer “antilocale” until the whis-
tling stops (Larsen effect).
