ACS INTEROPERABILITY NOTES
ACS INTEROPERABILITY NOTES
• Card ID offsets require special consideration in the Access
Control Software when the WQXM-PG is used with a Mer-
cury Panel.
• If multiple card formats are configured in the system, as
long as there are no Card ID collisions between the mul-
tiple formats, then the Card ID offset for each format can
be set to zero. (This is also called the Card Number offset,
Card Format offset or Cardholder ID offset.)
• If a Card ID offset must be configured due to Card ID
collisions, then non-overlapping Card ID offsets MUST be
configured for each of the card formats, and each offset
must be bigger than the max Card ID of all cards.
• If any of the Card ID offsets overlap and are
big enough,
then it may be impossible for the event (transaction) mes-
sages to properly identify the cardholder who performed
an action at a door lock.
• Resets issued to the Mercury SCP or SIO (Wi-Q Gateway)
from the ACS will also cause the Wi-Q Gateway to reset.
• Once the reset is received, it can take 4-5 minutes for the
Wi-Q Gateway to be restored to full communication status.
• The Mercury Panel currently inserts its own timestamp in
transactions sent up to the ACS. If there have been accu-
mulated transactions in the Controller or Gateway, when
those transactions are later delivered to the Mercury Panel,
the panel will re-timestamp the transactions with the cur-
rent time-of-day replacing the timestamp from when the
event actually occurred. This issue will be fixed in a future
release of the Mercury Panel firmware. Check the latest
release notes from dormakaba and Mercury to see if this
functionality has changed.
