Connecting Contact Alarms to a Fusion Wideband System

7-56 InterReach Fusion Wideband Installation, Operation, and Reference Manual

CONFIDENTIAL D-620616-0-20 Rev F

7.7 Connecting Contact Alarms to a Fusion Wideband

System

The Fusion Wideband 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 7-57)

The Fusion Wideband Main Hub has two alarm contacts, fault (major) and warn-

ing (minor). These contacts are normally-closed (NC) and will open when an inter-

nal 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 Wideband 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 7-60)

The Fusion Wideband Main Hub can monitor 3 external alarm contacts. Each port

can be configured 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 Wideband Main Hub

is connected, cable(s) used, and the faults and warnings that are detected.

Table 7-8 Alarm Types

Note that FlexWave Focus supports only faults (major errors).

In addition, a custom daisy-chain cable-to-BTS interface

cable is required. Make this interface cable to the desired

length and with the appropriate pin placement.
