Honeywell MAXPRO-NET manual Prioritizing Operators, Settling Conflicts In Monitor Access

9.8PRIORITIZING OPERATORS

As the system can be controlled by more than one keyboard at the same time, it is sometimes possible to have a situation where a conflict of monitor access and PTZ camera control arises.

The MAXPRO-Net system handles such conflicts by prioritizing all system operators. There are a hundred (0 Ù 99) possible operator priority codes.

With the exception of priority code (0), the level of priority relates directly to numerical code assigned (that is, 1= highest, 99= lowest). Priority code (0) indicates a special right of access. It is one which always has an exclusive access right (higher access level) over every other priority code (other than another 0).

CAUTION: The control of other system devices, like VCRs, motion detectors, and so on, are also prioritized accordingly.

The following table illustrates how the MAXPRO-Net System handles conflicts in operator priorities when selecting monitors:

Priority conflict	Operational Outcome
HIGHER verses LOWER	The Higher priority operator displaces the Lower priority
	operator from the monitor.
SAME priority levels	Both operators have equal (and concurrent) access to the
	monitor.
EXCLUSIVE verses ANY-OTHER	The Exclusive priority operator always displaces Any-other
	priority from the monitor (except for another exclusive
	priority).
EXCLUSIVE verses EXCLUSIVE	The first Exclusive priority operator will prevent the other
	from accessing the monitor, on a first in, first served basis.

Table 9.1: Settling Conflicts In Monitor Access

The above table also applies when controlling PTZ cameras, VCRs and other device, even when the keyboard operators are selecting the same device on separate monitors.

WARNING: Control priorities are only asserted when a keyboard control action occurs and not when the device is selected for display.
