Operation
The ACC2500 provides system control of a GAI-Tronics wide-area broadcast system consisting of an
Audio Messenger Interface (AMI), amplified addressable speakers and/or stanchion broadcast products. It
allows selection of individual units or zones and selection of preprogrammed speech/tone alarms.
Audio that is output from the AMI is directly routed to the integral speaker or handset to allow direct
monitoring of the AMI audio by the ACC2500 operator.

×16-character super-twist LCD display to provide valuable operator

CHECKING PARAMS , and line 2 shows: PLEASE WAIT.
