Connecting Contact Alarms to a Fusion Wideband System
Using a Base Station to Monitor Fusion Wideband
NOTE: The BTS must be configured, by the carrier, for contact closure monitoring
prior to connecting a Fusion Wideband Main Hub to it.
When you connect a BTS to Fusion Wideband, the Fusion Wideband Main Hub is the
output of the alarms (alarm source) and the BTS is the input (alarm sense), as shown
in Figure 7-31. An interface cable is required between the daisy-chain cable and the
BTS. Because BTS alarm interface pinouts and Fusion Wideband-to-BTS distances
vary, this cable is often custom and wired on-site. Refer to Section 3.2.1 for Alarm
Contact details (Normally Closed).
Figure 7-31 Using a BTS to Monitor Fusion Wideband
NOTE: For normally open contacts, the fault and warning contacts need to
be wired in parallel with other Main Hubs.
NOTE: LGC Wireless does not recommend using normally open contacts.
