“Door Open” indicator.
This function enables displaying a “Door Open” signal on the video door entry unit through the ignition of an
appropriate icon; this application is useful to avoid unwanted access to the housing unit.
To enable this function it is necessary, when the door is closed to connect a sensor with a N.O. contact to the
terminals ‘PA' and 'M' of the panel of the Two Wire system.
The icon turns on when at least one of the enabled doors closes the contact on the respective panel.
