7.4.2.1 Configurable functions (via inputs)
a)
Free pass:
Activation : send entry and exit commands at the same time and keep them active.
The free pass mode is appropriate for situations that demand that the system remains
cleared for an indeterminate amount of time and without passage control. It can used
as an emergency mode where legislation allows simple control for clearing; where the
legislation is more demanding, a general switch must be used to turn off the power to
the system, leaving the door free.
During the free pass mode, the door remains open for the exit and the upper
pictograms blink indefinitely. This mode remains active while the enabling signals for
entry and exit are present.
b) Bidirectional clearance:
In this mode, the equipment waits for user interaction to know in which direction it
should clear the passage and, thus, open the door correctly. This interaction happens
when the user pushes slightly on the door in the direction of passage after the
equipment indicated clearance. This type of clearance is useful especially for passages
that share the same reader for both directions.
Activate the bidirectional clearance by sending the entry and exit command at the
same time during the minimum enabling time of 20ms.
