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 inter-
coms 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 distribu-
tor.
- Telephones can be used instead of intercoms (see
"telecommunication" section).
- For other types of push-button panels see the general
catalogue.
When using MD100 and MD200 amplified external door
stations, it is advisable to place this diagram on the
diagram of page 119 and line it up with the riser.
For AC powered wires refer to the indications on page
111.

Connection of 1281E power supply-timer
instead of 1281 plus 1282E.

By adding 1281E to the schematics on
pages 118 and 119 instead of 1281 plus
1282E, the system working will modify as
follows:
- switching-OFF at the end of the timing only
- no control switch-ON interruption with the
video intercoms during external audio-
video connection. If the service is neces-
sary, add 1471 relay in order to interrupt
conductor 4.
