1.0 INTRODUCTION
The Liebert iCOM Discrete Output interface card provides dis-
crete outputs for Liebert Precision Cooling units equipped
with a Liebert iCOM control. Operating status is monitored
and critical alarms are communicated via contact closure. Any
alarm monitor, I/O panel, autodialer or monitoring system can
be used to monitor your Liebert unit.
The Liebert iCOM-DO card is available as a factory-installed
option or in a kit for field-retrofit to Liebert Precision Cooling
units equipped with the Liebert iCOM control.
