Control Panel Operation
CP 3000
6−12 CM 4000 Installation and Operating Manual
If entry of a password is requested, please see Passwords on page 6−22.
The L symbol in the display status line will be removed. The output is now available for control by any panel in the system.
Protect − On Jupiter control panels with a PROTECT button: after a given source has been switched to
a given destination, and PROTECT is pressed, the source for that destination can then be changed only
at the panel which protected the output.
Lock − On Jupiter control panels equipped with a LOCK button (except MC 3020L): after a given source
has been switched to a given destination, and LOCK is pressed, the source for that destination can then
be changed only at the panel which set the lock; and only after LOCK is pressed again.
Note 1: If another panel was used to protect/lock the output, the name of the panel will be shown (on panels
equipped with alphanumeric displays). The panel names and corresponding device addresses can be found
on the MPK Devices table (Figure 5−89); to determine the device address (ID) of a particular panel, please
see page 6−21. A panel name such as “Poll 1−075” refers to a party line control panel, in this example,
a panel with a polling address of 075 (hex) connected to the first PL 3000 listed in the Network Devices
table.
Note 2: An output can be force unprotected/unlocked from a panel equipped with LOCK/PROTECT
buttons if the panel’s password level is 90 or higher. This allows the panel to override the lock or protect
status of another control panel, including Master Control. Care must be exercised when using this func-
tion.
— To permanently change a panel’s password level using the file server, see Setting Password Levels for
Control Panels on page 5−113. This procedure will require downloading a revised set to the controller
board.
— To change a panel’s password level to “99” at the panel itself, see Raising Password Level To Maxi-
mum on page 6−22.
Note 3: A “force unprotect/unlock” function is also available using (1) JNS Force Unlock application
(page 11−1); (2) the Router Save/Restore utility (page 18−1); and (3) with the optional VG 3000 Video
Display/Status Generator (page 6−140).
Note 4: A panel can only protect/lock levels that are assigned to the panel with the CP Level set (page
5−58).
Note 5: An unlock command will unprotect an output but an unprotect command will not unlock an output.
