1. In standby mode, the receiving slot of the card capture reader is constantly backlighted by the
built-in LED indicator. The access card identifier, inserted into the receiving slot, is read by the
integrated reader and sent for analysis to the external ACS controller.
2. If the presented card is an employee’s permanent card and does not require withdrawal, the
ACS controller allows the passage through the turnstile in the set direction (gives the
appropriate signal to the turnstile control mechanism). The shutter, blocking access to the card
collector, remains closed, preventing the accidental withdrawal of the card. The backlight of the
card slot remains constant.
3. If the presented card is a visitor’s temporary card and requires withdrawal, the ACS controller
sends a control signal to the input of the card capture reader control board "Withdraw card"
(INPUT contact of the XT1 connector, see Fig. 10). The backlight of the slot for receiving cards
will switch to flashing mode with a frequency of 2 times per second, indicating that the card is
subject to withdrawal.
4. If after this signal, the optical sensor detects the presence of a card in the receiving slot, then
the card capture reader electromagnet opens a shutter blocking access to the card reader
container, and the card falls into the card receiving container – it is withdrawn. If the card is not
fixed in the receiving slot, then the electromagnet will not work and access to the inside of the
card reader container will remain blocked.
5. The second optical sensor registers the fact of withdrawal when the card is dropped into the
container. The card capture reader closes the shutter; the backlight of the receiving slot
becomes constant again. In this case, the "Card withdrawn"(OUT contact of the XT2connector,
Fig. 10) control signal is sent from the output of the control board of the card capture reader to
the ACS-controller and serves as a confirmation of the withdrawal of the card and activates the
passage permission. Upon receiving the signal, the ACS controller allows passage in this
direction (sends a corresponding signal to the turnstile control mechanism) and, after passing
through the turnstile, removes the “Withdraw card” signal. Upon removal of the “Card
withdrawn” signal, the card capture reader removes the “Card withdrawn” signal.
6. The third optical sensor monitors the fact that the card reader container is filled. When it is full,
the card capture reader sends an “Alarm” signal to the ACS controller (Alarm contact of the XT2
connector, Fig. 10), the backlight of the card capture reader slot will switch to flashing mode
with a frequency of 1 time per 2 seconds, thereby warning that the container is to be emptied.
The card capture reader operation will be blocked after it has received another 9 cards if the
container is not emptied. Unlocking of the card capture reader and deactivation of the "Alarm"
signal will occur automatically when the container is emptied from cards (Sect. 9.5). Also, the
“Alarm” signal is sent to the ACS controller in the event of a malfunction of the card capture
reader mechanism.
Parameters of control signals:
The “Capture card” input is controlled by an output of a dry contact type or open collector of the
ACS controller. The input is normally open, i.e. when a control signal is sent the ACS controller
closes the input to the “GND” contact (contact 4).
Input parameters:
Voltage at the opened contact relatively to the “GND” ..................................................... 5±0,5 V
Voltage at the closed contact relatively to the “GND”.................................................. max. 0.8 V
Current through the closed contact.......................................................................... max. 1.5 mA
The OUT “Card withdrawn”and “Alarm” outputs are of the dry contact type. Each of these inputs is
one of 2 relay contacts. Other relay contacts are banded and connected to a “COM” output
(contact 7). The outputs are normally open, i.e., when a signal is issued, the corresponding output
is closed to the COM contact.
Output parameters:
Maximum voltage between a corresponding output and “COM” contact ............................... 42 V
Maximum commutation current ...................................................................................... 200 mA
