PB3 –AMI Message Diagnostics
The AMI is programmed using the GAI-Tronics ACT tool and the messages and tones are stored in no
particular order on the device. In order for the ACC2500 to allow user selection of the preprogrammed
alarms, it must read the table of contents from the AMI when necessary. To select a particular alarm, the
ACC2500 operator simply scrolls to the desired alarm. However, to support the programming of preset
zones with preset alarms, the message number of the desired alarm must be known. This diagnostic allows
the installer/programmer to retrieve the message number as stored in the AMI of each message/alarm.
Upon entry into this diagnostic, the message number and alarm name of the first message in the list will be
displayed as seen below.

programming the ACC2500 using GAI-Tronics’ CARD Suite, this is the number that is used to configure a
preset alarm.

buttons scrolls through the list of available alarms. Pressing

Time Setting
This feature allows the user to set the time in the AMI. The time is available in 24 hour format. To access
