Connecting Contact Alarms to a Unison System
7-44 InterReach Unison Installation, Operation, and Reference Manual

Using a Base Station to Monitor Unison
When you connect a BTS to Unison, the Unison Main Hub is the output of the alarms
(alarm source) and the BTS is the input (alarm sense), as shown in Figure 7-13. An
interface cable is required between the daisy-chain cable and the BTS. Because BTS
alarm interface pinouts and Unison-to-BTS distances vary, this cable often is custom
and wired on-site. Refer to “Main Hub Rear Panel Connectors” on page 3-8 for
Alarm Contact details (Normally Closed).
Figure 7-13 Using a BTS to Monitor Unison
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.
