– Virtual wire entities—You can provision an alarm that is input to a virtual wire to trigger an
external control output.
16.6.3 Virtual Wires
Provisioning the AIC and AIC-I card provides a “virtual wires” option used to route external alarms and
controls from different nodes to one or more alarm collection centers. In Figure 16-4, smoke detectors
at Nodes 1, 2, 3, and 4 are assigned to Virtual Wire #1, and Virtual Wire #1 is provisioned as the trigger
for an external bell at Node 1.
Figure 16-4 External Alarms and Controls Using a Virtual Wire
When using AIC virtual wires, you can:
• Assign different external devices to the same virtual wire.
• Assign virtual wires as the trigger type for different external controls.
