2.4.3 Using Alarm Contact Closures
The DB-9 female connector on the rear panel of the Main Hub can be connected to a
local base station or to a daisy-chained series of Unison, LGCell, and/or MetroReach
Focus systems.
• When you connect MetroReach Focus or a BTS to Unison, the Unison Main Hub
is the output of the alarms (alarm source) and Focus is the input (alarm sense).
• When you connect LGCell to Unison, the Unison Main Hub is the input of the
alarms (alarm sense) and the LGCell is the output (alarm source).
Refer to Section 6.7 on page 6-34 for information on how to connect other equipment
to a Unison system for monitoring.
