new Authorization keycard with the same number as the Authorization keycard to be
cancelled, and swipe it through each FDU. The time stamp of the new Authorization
keycard becomes the current time stamp for determining whether an Authorization
keycard with the same Authorization number is valid. (This cancels all previous
Authorization keycards with that number.) This technique provides a high level of
security.
2.6.2
Date and Time Stamped Audit Trail
When a keycard is inserted in a lock, the lock audit trail is updated, including information
on the keycard that was inserted, and the date and time that the entry occurred. The time
of each transaction is also recorded in the FDU audit.
2.6.3
Keycard Expiry Date and Time
Each keycard has an expiry time stored directly on the keycard, after which the keycard is
no longer valid.
2.6.4
Keeping the System Synchronized
Because of the importance of time, it is recommended that all the FDUs on a property be
synchronized periodically, usually twice a year, by transferring data from one FDU to the
others. Each time an FDU is used to program a lock or reset lock addresses, and after
every battery replacement in a lock, the lock's internal clock is reset by the FDU to ensure
the entire system remains synchronized. The time in each lock should be reset twice per
year, if the FDU has not communicated with the lock during the past six months. Refer to
Section 3.5.4 – Transferring Data to Another FDU
for more details.
Another situation where FDUs should be synchronized is when PINs are created as a
substitute for certain types of authorization keycards. For more details please refer to
sections
3.5.5 – Pin Management
and
4.2.6 – PIN Usage as an Alternative to
Authorization Keycards
.
2.6.5
Daylight Savings Time
The local time shown on the FDU screen is not the same as the FDU's internal clock time
(or the system time). The FDU's internal clock should be set only when the system is first
installed. The local time can be set separately in the FDU features, and daylight savings
time is handled by moving the local time ahead or back by one hour. Refer to
Section 3.6,
part 10 – Current Time
for more details.
2.7 Audits
The lock audit can be consulted in the event of unauthorized access to determine which
keycard was used, when entry occurred, and the identity of the operator who issued the
keycard. The lock audit trail also records the use of special keycards such as Reset,
