5.2.1 Users
The Users list is one of the crucial parts of the intercom configuration. It contains user
information relevant for such intercom functions as quick dialling, RFID card/code door
unlocking, missed call e-mails and so on.
The User list contains up to 10 000
users –
typically, each user is assigned just one position. The
User list provides information on the users that are granted access to the building via the RFID
cards.
If your external card reader is connected to the intercom via the Wiegand interface, the card ID is
shortened to 6 or 8 characters for transmission (depending on the transmission parameters). If
you apply a card to the reader, you will receive a complete ID, which is typically longer (8 chars
or more). The last 6 or 8 characters, however, are identical. This is useful for comparing card IDs
with the intercom database: if the IDs to be compared have different lengths, they are compared
from the end and match has to be found in 6 characters at least. If they have identical lengths,
all the characters are compared. This ensures mutual compatibility of the internal and external
readers.
All cards applied via the reader or the Wiegand interface are recorded. Refer to
the
Status
/
Access
Log
menu for the last 10 cards including the card ID/type, card tapping time and other
information if necessary. With small systems, you can make a trick to enter card IDs: tap the card
on the intercom reader and find it in
the
Access Log
. Double-click to select the card ID and push
CTRL+C. Now that you have the card ID in your box, you can insert it with CTRL+V in any
intercom setting field.
Having been read, the card ID is compared with the intercom card database. If the card ID
matches any of the cards in the database, the appropriate action will be executed: switch
activation (door unlocking, etc.). To change the switch number to be activated, use
the
Associated Switch
parameter
in
the

menu
or
the

parameter
in
the

menu of
the card reader module.
