Class ChillerAlertListener

java.lang.Object

org.lsst.ccs.subsystem.refrig.ChillerAlertListener

All Implemented Interfaces:

EventListener, org.lsst.ccs.framework.HasLifecycle, org.lsst.ccs.services.alert.AlertListener

public class ChillerAlertListener
extends Object
implements org.lsst.ccs.services.alert.AlertListener, org.lsst.ccs.framework.HasLifecycle

Listen for alerts from specified other subsystems; for a safety-related alert which at alarm level is meant to shut off chiller flow, raise a corresponding chiller-subsystem aler.
