Connection of 2 door locks with simultaneous opening
If it is necessary to operate the 2 door locks of the system at the
same time, you must:
- add a 12Vac transformer with suitable power (type PRS210)
- add a 12Vac relay (type 1471)
- make the connections as shown in the diagram below.
Control switching ON deactivation
To activate the control switching ON from the
intercoms only when the system is in standby,
it is necessary to install a relay (type 1471 or
1472) and connect it as shown on the dia-
gram.

Notes
- For the connection of name plate lamps read notes 6, 7 and 8 of the
installation instructions on page 111.
- If the control switching ON is necessary, connect terminal 4 of the timer
(dashed wire).
- To install a colour system, the ST7100CW video intercoms and the
MD41C, MA42C, MA43C, PL40PC, PL41PC or PL42PC camera must
be used.
- For wires dimensioning and video connection refer to the installation
instructions and table on pages 111÷113.
- For one-way systems connect the coaxial cable to the monitor bracket
directly, without using the video distributor.
- Telephones can be used instead of intercoms (see “telecommunication”
section).
- For other types of push-button panels see the general catalogue.
