SET LCD ACCESS PASSWORD
6.11.1 FUNCTION
Allows an operator to change the LCD Access Password. This password, when entered
correctly, allows:
(i)
Alteration of the password itself.
(ii)
Alteration of the sensitivity settings of analogue detectors configured in the system.
6.11.2 OPERATING SEQUENCE
To set the LCD Access Password, press:
The LCD will prompt for the current password. Enter the current password. The LCD will
then prompt for the new password, which should be entered. The LCD will then prompt for
the new password again, to confirm that the new password was entered correctly the first
time.
The FIP will then store away the new password, and re-calculate the database CRC.
The display then reverts to the SET SYSTEM MENU, so that other SET SYSTEM changes
can be made, if required.
6.11.3 NOTES
(a)
All passwords consist of 0 to 10 numeric digits.
(b)
All passwords are echoed with * instead of the actual digits entered.
(c)
The CLR key can be pressed to allow re-entry of a password if an operator is not
sure of what was previously entered.
(d)
The LCD password can also be set by service personnel using the programming
terminal.
(e)
The password cannot be altered if there is a System, Automatic or Powerup test in
progress, if the programming terminal has stopped processing, or if the EEPROM
cannot be written to.
