FONCTION D’AUTOALLUMAGE EN BOUCLE. VIDÉO PORTIER 2 FILS
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.
