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.
