Connecting Contact Alarms to a Unison System
NOTE: LGCell and FlexWave Focus support only faults (major alarms).
Do not mix LGCell and Unison Main Hubs in the same daisy-chain. You can
daisy-chain multiple LGCell Main Hubs together and use the Alarm Sense Adapter
Cable to connect the chain to a Unison Main Hub, which will act as an alarm sensor.
7.7.1 Alarm Source
Unison always acts an alarm source, no matter what type of equipment you are con-
necting to. Refer to Section 7.7.2 on page 7-46 if you want Unison to sense LGCell
contact closures or other external alarms.
Using FlexWave Focus to Monitor Unison
When you connect FlexWave Focus to Unison, the Unison Main Hub is the output of
the alarms (alarm source) and Focus is the input (alarm sense), as shown in the fol-
lowing figure. Focus supports only faults (major alarms).
