Connecting Contact Alarms to a Fusion System
Using a Base Station to Monitor Fusion
NOTE: The BTS must be configured, by the carrier, for contact closure monitoring
prior to connecting a Fusion Main Hub to it.
When you connect a BTS to Fusion, the Fusion Main Hub is the output of the alarms
(alarm source) and the BTS is the input (alarm sense), as shown in Figure 7-23. An
interface cable is required between the daisy-chain cable and the BTS. Because BTS
alarm interface pinouts and Fusion-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 7-23 Using a BTS to Monitor Fusion
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.
