3. MODE WITH EXTERNAL AUDIO UNIT
Generic/coded actuator modes can also be used on a system which
includes an audio-only external unit Art. 1622 - 1621.
For operation with "audio only" external unit:
1. set DIP 1 of selector "S1" as illustrated below:
2. set the external unit to video mode as shown in the picture below
In this mode, every time a call is received from the external unit or
when self-ignition takes place, the monitor switches on and displays
the image from the first camera connected to Art. 1409. It will be
possible to cycle through all cameras connected by repeatedly
pressing the programmed button.
4. MODE WITH SWITCHBOARD 1998A
Generic/coded actuator modes can also be used on a system which
includes Video calls from switchboard.
In this mode, every time a video call is made from the switchboard,
the monitor switches on as soon as the handset is lifted (or the audio
button is pressed), and the image displayed will be the one from the
first camera connected to Art. 1409.
At this point, each time a control button is pressed (see generic/
coded actuator modes) or each time the manual contact is closed
:
(available by connecting the INA-GND contact to the OUT-OUT
terminals of the switchboard as per diagram IK/EN/004QC), you will
be able to cycle through all available cameras.
„ To use this function, the remote camera module must be
connected to the outgoing Bus line from terminals LM-LM of the
switchboard, and the switchboard set to "Video mode" before
the call.
