6.6.2 Alarm Sense
Use AdminManager to enable the Unison Accel system for “alarm sense” when con-
necting to the contact closure of LGCell Main Hubs or other external alarms (see Set
Contact Sense Properties in the AdminManager User Manual).
Using Unison Accel to Monitor LGCells
When you connect LGCell to Unison Accel, the Unison Accel Hub is the input of the
alarms (alarm sense) and the LGCell is the output (alarm source), as shown in the fol-
lowing figure.
Figure 6-10 Connecting LGCell to Unison Accel
LGCell supports only faults (major errors). You must use the Alarm Sense Adapter
Cable (see page 6-35) to interface the daisy-chain cable to Unison Accel. The adapter
cable is required because it translates the LGCell fault pinout to the sense input pins
on the Unison Accel Hub.
