PUSH-BUTTON PANELS
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
front frames shields which have been described
on pages 20 to 25. Only the CCD cameras and
the modules with door speaker are different,
in that they have not been adapted for function-
ing with a reduced number of wires (product
MA43ED, MA11PED and MA12PED must be
used).
AMPLIFIED DOOR STATIONS
MA11PED. Module with front plate and 1 call
button in stainless steel, red operation LED,

module to the corresponding terminal on MA24
module; if MA22 module is used do not connect
P3 and P4 conductors and properly insulate
them.
