7.7.2 Alarm Sense
Use AdminBrowser to enable the Fusion Wideband 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 Wideband to Monitor Unison
When you connect Unison to Fusion Wideband, the Fusion Wideband Main Hub is
the input of the alarms (alarm sense) and the Unison is the output (alarm source), as
shown in Figure 7-36. The input alarm sense needs to be set to normally closed (NC).
Figure 7-36 Using Fusion Wideband to Monitor Unison
Unison supports only faults. You must use the Alarm Sense Adapter Cable to inter-
face the daisy-chain cable to Fusion Wideband. The adapter cable is required because
it translates the Unison fault pinout to the sense input pins on the Fusion Wideband
Main Hub.
