Si 36MO/5
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.
Working instructions
It is similar to the basic system described on page 94, but with the
following variations:
- Carrying out a call from the entrance only audio, the corresponding
monitor turns itself ON without images.
- The audio-video operations and the door lock release are automati-
cally switched at the time of the call or with the control switch ON.
- The services towards the secondary video entrances are indepen-
dent among themselves and therefore they can function at the same
time.
Notes
- Connect the video intercom terminal 4 (wire shown with dotted line)
and apply 2 diodes (1N4007 type; 100V-1A) for every secondary
door station, if the control switch on is required.
- For the connection of name plate lamps read notes 6, 7 and 8 of the
installation instructions on page 91.
- For wires dimensioning and video connection refer to the installation
instructions and table on pages 91÷93.
- 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).
- On bracket of the videointercoms you must move jumper J1 from
position 2-3 to 1-2. If the private conversation is necessary, use the
Si36MO/3 diagram.

secondary door station instead of electric door speaker MD30
