I /O Applications 2
Creating a Group for Cascade Triggers
You can group I/O devices by function or geography. Further, the group allows cascade triggers,
meaning that the trigger actions of one trigger can activate another trigger.
For example, you might have a group called “Entrance” that contains all I/O devices installed at
entrances. The “Entrance” group might contain other sub groups, each of which contains just the
related I/O devices in various geographic locations:
Group containing all I/O devices installed at entrances
Input 2 installed at the front entrance
Output 1 sub group at the kitchen
Output 3 sub group at the garage
Figure 2-14
When Input 2 is triggered, it will trigger the sub groups of Output 1 and Output 3, and Output 1 will
trigger Output 2 in a cascade series.
Creating a Group:
1. Right-click on Advanced I/O List, and then select Add A Group. This dialog box appears.
Figure 2-15
„ Group Name: Names the group.
„ Invoke Alarm: Invokes the computer alarm on I/O trigger. Select a sound from the drop-down
list.
„ Enable advanced logical input in Multicam: See Setting Advanced Logical Input Status
later in this chapter.
2. Click Save to apply the settings, and return to the panel.
3. To create a cascading hierarchy, drag the desired inputs/outputs from the left Standard I/O List to
the group.
Note: In the cascading hierarchy, each input can only be used once while the same output can be
used repeatedly.
