4101-2 Controller Installation Handbook
5-8
When the module is first installed in the Controller and switched on,
it is not polled and the LEDs are off. For a reader to start being
polled, it must be configured in the Access Configuration part of the
Access Control Software. Use the Update System List command in
the Hardware Systems part of the Access Control Software to see
what modules are installed and whether they are configured. When
you configure the reader, if the system is on line, the necessary
commands are downloaded to the Controller immediately and the
reader starts to work. The LED for that reader flashes steadily.
When a card is swiped, the LED flashes with a different pattern, so
you can see if the module is receiving data from the card reader.
Door indicator LEDs
How you use the red, green and amber LED outputs from the module
depends on the card reader you are using, how many LEDs it has
and how they are driven. All three LEDs can be provided by a 272
Remote Indicator mounted next to the door. The three LED outputs
from the module are common anode (VA) 12V, the cathodes being
switched from
,
and
G
.
The swipe card module LED outputs have the following meanings.
Green
Access granted - the door is unlocked.
Red
Access denied - the reader is operational and ready to read a card. A
red LED output normally means that the door is locked. However,
when anti-passback is in use a card reader may be positioned on
either side of the same door. In this situation, someone can swipe a
card on one side and unlock the door while the LED on the other side
continues to show red.
Amber
The amber LED gives information about cards which are read by the
system. Its function depends on whether the red LED is lit or the
green LED is lit when the card is swiped.
When the red LED is lit:
• A valid card swipe unlocks the door, the red LED goes out and
the green LED lights for the duration of the relay time. The
amber LED does not light.
• An invalid card swipe lights the amber LED for 1 second.
When the green LED is lit:
• A valid card swipe lights the amber LED for half a second to
show that the card has been correctly read.
An invalid card is one which is denied access because of one of the
violations specified on the Access Violations page of the System
Administration part of the Access Control Software.
