5.6 Groups
Groups allow the creation of screen hierarchies for displaying the pathway to an off normal device,
starting at a top level site view. Two levels of grouping, Level 1 and Level 2, are used to associate
devices with a single bitmap. A Level 1 group can have either Level 2 groups or actual devices
associated to it. A Level 2 group must be associated upwards to a Level 1 group (in the floor plan
hierarchy), and will have devices associated below it. The two levels of grouping plus the floor
plan where the actual off-normal device is located offer three main view levels for floor plan
navigation. These levels coupled with Navigation Buttons offer a variety of setup possibilities for
graphics.
The graphics are no longer limited to one top screen, therefore the “Home Screen” is the first screen
created. This screen is shown on NCS / GSP Startup. This ability to have many top screens means
that Level 1 Groups can exist on different screens, each representing the Top Screen of a different
graphic path.
5.6.1 Level 1 Groups
A Level 1 group requires a normal state bitmap and a description. A label is created from the
Group description and displayed bottom center of the group bitmap. This label flashes when an
off-normal event is received for an associated device. The flashing occurs by alternating the
normal group description with the color and text of an off-normal event. Optional active and
trouble bitmaps can be assigned to a group for these conditions.
5.6.2 Level 2 Groups
A Level 2 group requires an associated Level 1 group name, normal state bitmap, and a description.
An optional active and trouble bitmap can be assigned and displayed when any off-normal
conditions occur for the group. The Level 1 groups are selected from an available list box. If no
Level 1 groups exist, an error message is displayed and the Level 2 setup is cancelled.
A label is created from the group description and displayed bottom center of the group bitmap.
This label will flash when an off-normal event is received for an associated device. The flashing
occurs by alternating the normal group description with color and text of an off-normal event.
5.6.3 Group Setup Restrictions
The following are restrictions for groups:
• If a device on a floor plan is associated with a group, then all other devices on that floor plan
are automatically restricted to the groups contained on the screen where the associated group
resides. In other words, if L1D1 is associated with a specific group 2, then L1D2 on that floor
plan must also be associated with group 2, or another group on the screen where group 2
resides.
• Screens can contain group 1 icons or group 2 icons, but they can not be intermixed. If a floor
plan has a group defined, all other groups on that floor plan must be of the same level, either
Level 1 or Level 2.
5.6.4 Group Navigation
If a device goes into alarm or trouble, while auto-vectoring is off and a floor plan is displayed that
contains the device linked, then the screen with the group containing the device where the event has
occurred will appear and the group label will flash. This can indicate that an off-normal condition
has occurred within the area that the group monitors. Double clicking on the group will either
invoke the floor plan containing a Level 2 group (assuming that the first group was a level 1 group),
or the device that is off-normal. If a Level 2 group is defined, then the floor plan containing this
group will be invoked, and change to its off-normal bitmap. Double clicking now will invoke the
off-normal device.
If the device is directly linked to the top level group, then double-clicking on the device will invoke
the floor plan that contains that group.
