Passwords
Various menu functions are accessible or inaccessible,
depending on the access level of the user, and the password
they enter, if any. There are four access levels, including no
password, Level 2, Level 4, and Level 6, with Level 2 having
the highest level of access. Without entering a password, the
user has access only to basic status menu items. Entering
the Level 6 password (5321) allows access to the Alarm Lists
Menu, Quick Menu, and the View/Set Unit Menus group.
Entering the Level 4 password (2526) allows similar access
as Level 6 with the addition of the Commission Unit Menu,
Manual Control, and Service Menu groups. Entering the Level
2 password (6363) allows similar access as Level 4 with the
addition of the Unit Conguration Menu.
NOTE: Alarms can be acknowledged without entering a
password.
The main password page is displayed when the keypad/display
is rst accessed, the Home Key is pressed, the Back Key is
pressed multiple times, or if the keypad/display has been idle
longer than the Password Timeout (default 10 minutes). The
main password page provides access to enter a password,
access the Quick Menu, view the current Unit State, access the
alarm lists or view information about the unit.
