Locking or Unlocking an Output
Locking an output prevents that output from being switched by any panel
in the system, including the initiating panel.
To lock an output:
1. Press the LOCK button.
This has the effect of locking only those levels this control panel can
control (as defined on the CP Level set assigned to the panel). The
LOCK
button will remain on, indicating the output has been locked by this
panel.
If another Jupiter panel selects this output for control, that panel's LOCK
button will light.
To unlock the output:
1. Press the LOCK button again.
The LOCK button lamp will go off.
If the output will not unlock, it has been locked by another panel.
For additional lock information - please refer to the Jupiter CM-4000 or
CM-4400 manual.
