Connecting Contact Alarms to a Fusion System
7.7.2 Alarm Sense
Use AdminBrowser to enable the Fusion system for “alarm sense” when connecting
to the contact closure of Unison Main Hubs or other external alarms (refer to Set
Contact Sense Properties in the AdminBrowser User Manual).
Using Fusion to Monitor Unison
When you connect Unison to Fusion, the Fusion Main Hub is the input of the alarms
(alarm sense) and the Unison is the output (alarm source), as shown in Figure 7-35.
The input alarm sense needs to be set to normally closed (NC).
Figure 7-35 Using Fusion to Monitor Unison
Unison supports only faults. You must use the Alarm Sense Adapter Cable to inter-
face the daisy-chain cable to Fusion. The adapter cable is required because it trans-
lates the Unison fault pinout to the sense input pins on the Fusion Main Hub.
