Connecting Contact Alarms to a Fusion System
7.7 Connecting Contact Alarms to a Fusion System
The Fusion Main Hub can generate (source) two contact alarms as well as sense three
external contact alarm.
• Alarm Source (refer to Section 7.7.1 on page 7-56)
The Fusion Main Hub has two alarm contacts, fault (major) and warning (minor).
These contacts are normally-closed (NC) and will open when an internal alarm is
detected.
NOTE: The contact can be changed to normally-open (NO) with Admin-
Browser. This is not recommended since no alarm would be sent if power to
the Fusion Main Hub fails.
• Fault is activated when any faults or disconnects are detected.
• Warning is activated when any warning conditions are detected except lockout
or when the end-to-end system test is not valid.
• Alarm Sense (refer to Section 7.7.2 on page 7-59)
The Fusion Main Hub can monitor 3 external alarm contacts. Each port can be con-
figured for normally-open (NO) or normally-closed (NC) contacts. The interface
expects a set of floating contacts, and an external voltage source is not required for
this interface. Use AdminBrowser to monitor the port status.
Table 7-8 lists the alarm types, equipment to which the Fusion Main Hub is con-
nected, cable(s) used, and the faults and warnings that are detected.
