Installation of supplementary external ringtones.
If it is necessary to transmit the call audible warning to different points of the system (large properties, etc.) or
boost its intensity, it is possible to install repeater relays or external ringtones.
If you install 12 Vdc relays (for instance, art. 0170/101) the "+12" and "CH" terminals of the video door entry unit
and, if you use the Elvox ringtone 860A powered from the mains, the terminals to be wired are "CH" and "M".
N.B.: If you are not using external relays, do not exceed a power draw of 100 mA from the "+12" output so as
not to cause malfunctioning of the video door entry unit.
Examples of installation:
Video door entry units with simultaneous video calls.
The need to install several video door entry units in parallel with simultaneous activation of the monitors
requires, for each video door entry unit starting from No. 2 onwards, using supplementary power supplies if all
the monitors have to switch on simultaneously.
