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, you must connect the dashed wires and the two terminals 1C and PC in each video intercom.
- 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.
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.

131 instead of 1281 plus 1282E, the system
working will modify as follows:
- switching-OFF at the end of the timing only
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 2-
