Working instructions. See page 115.
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 “telecommunica-
tion” section).
- For other types of push-button panels see the general catalogue.
- By using MD100 and MD200 amplified external door stations, we
recommend to place schematic on page 118 on the other on page
123.
Private conversation
When the intercom is installed with the monitor (video intercom
function), the service is provided by the bracket WB7100 (posi-
tion 2-3 of jumper J1).
If the user has the intercom function only, you must install the
SM50E private conversation module in the intercom and:
- (ST 720) - remove the mobile jumper inside the connector
JP2
- (KM 810) - cut jumper W1 joining terminals 3 and 0.
- connect terminal 0 of the intercom to terminal - (minus) of the
SM50E module.
Connection of 1281E power supply-timer
instead of 1281 plus 1282E.
By adding 1281E to the schematics on page
123 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.
