2.3.2 Using Alarm Contacts
You can connect the DB-9 female connector on the rear panel of the Fusion Main
Hub to a local base station or to a daisy-chained series of Fusion and/or MetroReach
Focus systems.
When you connect MetroReach Focus or a BTS to the Fusion, the Fusion Main Hub
outputs the alarms (alarm source) and MetroReach Focus or the BTS receives the
alarms (alarm sense). This is described in Section 7.7.1 on page 7-50.
Each RAU passes its status to
the Hub.
If a fault is detected, the
ALARM LED is red. If no fault
is detected, the LED is green.
The Expansion Hub queries
the status of each RAU and
compares it to the previously
stored status.
If a fault is detected, LEDs on
the front panel turn red.
