Working instructions.
As the basic system described on page 218, with the following variations:
- The audio-video functions and door lock opening are automatically switched to
the door station which has made the call (or control switching ON) and remain
in this state until a call from another entrance is received.
- Services to secondary door stations are independent and can be operated at
the same time.
- By making the call from the secondary audio station, the video intercom
remains switched OFF.
Notes
- For audio compatibility we do not suggest to connect door stations MODY
series with internal devices ECHOS series.
- If the control switching ON is necessary, connect terminal 4 of the timer (dashed
wire).
- DV.. distributors can be used instead of the video distributors 476 by adding
a power supply wire (from + to terminal 8 of every video intercom).
- For the connection of name plate lamps read notes 6, 7 and 8 of the installation
instructions on page 146.
- For wires dimensioning and video connection refer to the installation instruc-
tions and table on pages 146÷148.

Connection of the MD100 amplified external door sta-
tion to the secondary door station instead of electric
door speaker MD30 and module MD11.
Connection of two door locks, of which the
secondary is always activable, in a system with
multiple entrance
For this option it is necessary to
install a diode (100V-1A; type
1N4007) between terminals 7
(cathode) and 7a (anode) of every
secondary exchanger. The diode
allows to activate also the door
look of your own entrance when the door look of the
main entrance is activated. On the contrary when the
door lock of your own entrance is activated the door
look of the main entrance is not activated.
Connection of 1281E power supply-timer in-
stead of 1281 plus 1282E.
By adding 1281E to the schematics on page 213
instead of 1281 plus 1282E, the system working will
modify as follows:
- switching-OFF at the end of the timing only
