6.14 RECALL SYSTEM CRCs
6.14.1 FUNCTION
Allows an operator to view on the LCD the Database CRC and the time and date the
database was last changed.
This information can be used as part of an AS1851.8 testing schedule, and to provide for
detection of tampering with the system configuration.
6.14.2 OPERATING SEQUENCE
From any information display or base display, press:
The Recall System CRCs display may also be accessed by the SYSTEM RECALL 3
command sequence from the base display.
The LCD will display the database CRC, and the time and date that the database was last
altered.
NOTE: Programming terminal database changes, or changing detector sensitivities or
the LCD password from the LCD keypad, will change the database and thus the
numbers displayed as a part of this recall.
Thus, if the database is changed, the new numbers should be recorded in the log
book and the service company advised.
