often it may become possible for an actual fire condition to be compensated out. Agency
approval requirements like UL 864 are being established to prevent this from happening.
Differences Mode / Differences Report
Introduction
To access this dialog, select Compare Job Versions from the Job Menu.
The configurator has the capability of comparing two jobs. Once differences mode is
entered the job tree shows which elements have been added, removed or changed. The list
views show in more detail which items have been modified or whether correlations have
been added or removed.
In differences mode a report can be printed. The scope and depth of the print report can be
chosen, similar to when printing a single job.
The differences report is intended primarily to provide the authorities with a detailed list of
what has (and what has not) been changed. Such a report can used to justify only minor re-
testing of an installation.
Primary vs. Secondary Job
In this document we will refer to Primary and Secondary jobs. The primary is normally the
older job, currently in service. It is the base against which the secondary job - the newer,
modified job - is to be compared.
You will normally first establish the primary job by opening it using the Job Menu and
choosing the desired Job and Version. Then you will invoke differences mode, where the
secondary job is chosen.
This document occasionally refers to items that have been added or deleted. These terms
are used with respect to the primary - assuming that the primary is the older job. There is
nothing to prevent you from reversing this convention and establishing a newer job as the
primary.
Initiating Differences Mode
Differences mode can be initiated either by selecting Compare Job Version from the Job
Menu, or by clicking the Differences icon in the tool bar.
When you initiate Job Compare, the Job Compare Dialog is displayed.
Press OK to enter differences mode. This can take several minutes, as the program examines
every component of each job and decides if it is added, removed or changed. Correlations
are also compared during this phase. A changed correlation is reflected not only in the
correlations list, but is propagated (as a modification) up to the device or circuit list and
