ARM HiGain System
ARMED Armed to respond to Intelligent Repeater Loop Codes.
ACO Alarm CutOff A minor alarm has occurred and retired to an ACO
condition, by pressing the SEL button on the HLU front
panel.
SELF
TEST Self Test mode HLU is in self test mode. This occurs every power On/Off
cycle.
ALRM Alarm Condition
Exists A minor alarm MNRALM condition is in effect.
