THE LOOPED AUTO-SWITCH-ON FUNCTION
The auto-switch-on function makes it possible to see the image on the monitor, communicate
with the entrance panel and open the door without having received a call.
In installations with several points of entry this function can be activated sequentially in the
different entrance panels of the installation (looped auto-switch-on), by repeatedly pressing
the auto-switch-on button. Thus (See picture below), when the auto-switch-on button is first
pressed, the main entrance panel will be activated (P); then, as the button is pressed again
and again, each of the secondary entrance panels of the building will be activated in turn (S1
,S2,S3,S4,S5), until eventually the loop is completed and the main entrance panel is activated
once again. In compounds, and before returning to the main panel, the external panel defined
as the main panel (EP) will be activated, followed by each of the external panels defined as
secondary (ES1, ES2, ES3, ES4, ES5).
