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 the following fig-
ure. 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.
