Interlock GroupThe ECS user can assign several keys on a panel into an interlock group and restrict the group so that only one key of the group can be activated at any one time. This function only refers to talk paths. For example if a panel had five keys programmed to talk to cameras 1 to 5 then by setting these into an interlocked group only one camera key can be selected at a time.  There are nine available color coded interlocked groups to which the ECS user can assign any or all panel keys.  The interlock groups are specific to the panel they are programmed for and do not affect interlock groups that may be set up on any other panel in the system.
