PROTECT/UNPROTECT FUNCTIONS
CP 3832L
A CP 3832L will indicate when another panel has protected (or locked) an output by flashing the last selected input button.
The CP 3832L cannot protect/unprotect (or lock/unlock) an output.
CP 3864L
Protecting an output prevents that output from being switched by other panels in the system. The protecting panel may still
change the output.
To protect an output with the CP 3864L:
1. Press the Protect button.
This has the effect of protecting only those levels this control panel can control (as defined on the CP Level set assigned
to the panel). The button will blink “high” green, indicating the output has been protected by this panel. In addition, the
associated input button will also blink green.
If another panel attempts to switch this output, a “Protected” indication will appear on that panel.
To unprotect the output:
1. Press the Protect button again.
The Protect button will switch to “low” green.
If the Protect command is ignored, the output has been protected by another panel. To find out the name of the panel,
select an input button.
An output may be force unprotected, regardless of the panel that protected it, if the password level of the unprotecting panel
is level 90 or greater. The password level is defined on the MPK Device table (page 5−107). This operation is useful for a
master panel capable of switching any source to any destination. The operator would be required to force unprotect the output
prior to changing its source selection.
If another panel has protected (or locked) the output, the CP 3864 Protect button will blink red. In addition, the last selected
input button on the CP 3864L will blink green.
The CP 3864 cannot lock or unlock an output.
