Video door entry system
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 external bell repeaters.
To do this, uses the terminals '+12' and 'CH' in the case of ringtones that need an external relay at 12 Vcc (for
instance art. 170/101) while, if the Elvox bell 860A powered by the mains is used, the terminals to wire are 'CH'
and 'M'.
N.B.: It is necessary not to exceed the absorption of 100 mA from the output '+12' so as not to cause any mal-
functioning of the video door entry unit.

The need to install multiple video door entry units in parallel, with the simultaneous activation of the LCD monitors,
has requirements tied to their consumption of current that must be limited so as not to exceed the permissible
delivery of the main power supply 6922.
In the phase of configuration it is possible to set "call groups" (that are groups of video door entry units that at
the same time answer the same call) in two different modes that can be set via advanced programming with PC
and the USB 02024 interface with "SaveProg" software (for the details see chapter "CONFIGURATION OF THE
OPTIONAL FUNCTIONS OF THE VIDEO DOOR ENTRY UNIT"); these modes are:
1. Group call with only the master active at the call (so only the master video door entry unit is switched on).
2. Group call with all the group video door entry units active at the call (all the video door entry units are switched on).
