Pictograms
A pictogram indicates what the user can or should do in the direction in which he
presents himself. There are two types of pictograms:
-
orientation pictogram: it may display a red cross or a green arrow,
-
function pictogram: it may display a red cross, a green arrow or an orange card
Only one sign is lit at any time for each pictogram.
Two types of management are available for the pictograms: the
extended
mode and the
limited
mode.
If no pictogram has been installed on the PNG, it does not matter what type of
management is selected.
4.2.8.1.
Limited mode
This operation mode is applied if the operation pictogram is not installed or is not activated.
The orientation pictogram always informs the user about what he can or should do.
The "green arrow" shows that the passage is authorized.
The "red cross" shows that the passage is prohibited.
4.2.8.2.
Extended mode
In this mode, the two pictograms are installed on the PNG.
4.2.8.2.1. Orientation pictogram

4.2.8.2.3. "Passage authorization storage" configuration
If only one passage authorization is granted, the "card" turns into a "green arrow". When the
user is in the zone before the obstacle, the "green arrow" is replaced by a "card".
If several passage authorizations are in progress, the "card" becomes a "green arrow". When
the last user allowed to pass is in the zone before the obstacle, the "green arrow" is replaced by
a "card".
4.2.8.2.4. "No passage authorization storage" configuration
The “green arrow” appears after a passage authorization. The “red cross” appears when the
user is in the zone before the obstacle. The “card” is again displayed after detection of passage
through the obstacle.

When an alarm is activated after the detection of a fraud, in limited mode, the orientation
pictogram will display a “red cross” and in extended mode, the operation pictogram will display a
