Keyboard Passcode Entry
Passcode entry is a security procedure to allow only authorized
personnel to operate the AD1650B system. When USER IDS
is enabled (see USER IDENTIFICATION menu, page 4-28),
AD1677 and AD1676B keyboards cannot access the system.
The passcode entry system allows a maximum of 48 users with
a separate passcode for each user. The system default
passcode is 914365, for user number 1.
Note: The default user passcode should be changed to protect
against unauthorized access to the system. User passcodes
are changed by menu programming, see SET USER menu
page 4-29.
When passcode entry (USER IDS) is enabled, an operator must
have a user number and a user passcode to access the system,
through an AD1678CM or AD2078 keyboard only. The
following Passcode Logon and Logoff procedures must be
followed to gain access to any control or programming
functions in the AD1650B.
Passcode Logon
When an AD1678CM or AD2078 keyboard is initialized with
USER IDS enabled, the keyboard displays the letters “UC”
(User Code) in the CAMERA display section. This indicates
that the user must log on to the system before gaining access to
any AD1650B control or programming functions:
1. Enter the user number (1 - 48) on the keypad.
2. Press the ACK button on the keyboard.
The system then prompts for the passcode by displaying
“PSC” (Passcode) in the keyboard CAMERA display.
3. Enter the user's passcode, a maximum of six digits.
(The default passcode for user #1 is 914365.)
If an incorrect user passcode is entered, press the CLEAR
button, then repeat step 3.
4. Press the ACK button on the keyboard.
* If the passcode does not verify, a tone is sounded (if
keyboard sound is enabled) and “UC” is displayed again.
Press the CLEAR button and repeat steps 1 through 4.
* If the passcode verifies, the keyboard MONITOR and
CAMERA displays are cleared. This confirms that the
keyboard is connected to the system and that a monitor
can be called to the keyboard (page 2-3).
Passcode Logoff
When the user session is completed it is advisable to log off:
• Enter “99” on the keypad and press the keyboard “F1” key.
or
• Press the “USER” key on an AD2078 keyboard.
