-
reinforced detection:
“opposite direction” fraud is detected and an alarm is immediately
activated:
- the doors close in front of the authorized person unless the security zone is activated,
- the buzzer is activated,
- the pictograms show a red cross.
The alarm will end when the exit zone has been freed and after a short time-out (% TM6) (1 sec
by default). The doors will reopen if the authorized person has not yet passed through and the
time-out allowed for authorized passage is returned to zero.
-
reduced detection:
no fraud is detected; no alarm will be activated.
Entry through the free direction:
A user presents himself in the free direction and darkens the first cell, the doors open. While the doors
are open, a person enters in the opposite direction (through the exit zone). Two types of “opposite
direction” detection are possible:
-
reinforced detection:
“opposite direction” fraud is immediately detected.
-
reduced detection
: “opposite direction” fraud is not detected unless the user entering in the
free direction has left his entrance corridor or is still in the extension zone of the corridor.
If fraud is detected, the alarm is activated:
- the buzzer is activated,
- the pictograms show a red cross,
- the doors will remain open in “reduced detection” mode and will close in the “reinforced detection”
mode.
The alarm will end when the exit zone has been freed and after a short time-out (% TM6) (1 sec by
default). If a presence is still detected in the free entry corridor, the time-out allowed for free passage is
returned to zero.
Nota Bene:
Default “opposite direction” fraud is in reinforced mode but the reduced detection mode may be chosen
during the PNG configuration procedure (DIP6 of word 3).
Detection of entry in the exit zone will always take place over 3 cells in this case.
4.2.2.
Operation modes
The operation mode, programmed by an external control console or by DIP switches on the AS1007
board (
2:7
), defines the type of control exerted in both directions and the possible selection of the
"evacuation" mode.
4.2.2.1.
Obstacle state at rest
At rest, obstacles are positioned according to the state of the
SW3.6
DIP switch.In
Mode NO
,
the obstacles are open at rest and will close in the event of unauthorized passage.
The obstacles are closed at rest in
Mode NF
and will open in the event of authorized passage.
4.2.2.2.
Controlled direction A - Controlled direction B
A passage authorization is necessary to pass in directions A and B.
4.2.2.3.
Controlled direction A – Free direction B
A passage authorization is necessary to pass in direction A.
Free passage in direction B. From the moment the first cell (C12 or C9 if there is no extension)
has been darkened, the doors open (in mode NO, they remain open) and the direction B
pictogram shows a green arrow. The doors close again in mode NF when corridor B has been
freed and after a time-out (% TM1) (2 sec by default).
Choice of the type of “opposite direction” detection will take place in this operation mode. (see
4.2.1.4.)
