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.

2 1 : L OC K D OWN
The message number displayed on the second line corresponds to the alarm name indicated. When
programming the ACC2500 using GAI-Tronics’ CARD Suite, this is the number that is used to configure a
preset alarm.
Pressing the ALARM UP or DOWN buttons scrolls through the list of available alarms. Pressing
TRANSMIT exits this diagnostic.
Time Setting
This feature allows the user to set the time in the AMI. The time is available in 24 hour format. To access
the time setting feature, cycle the power to the ACC2500. When the display shows the unit’s firmware
version and the four programmable buttons are lit, press the
TIME button. Upon access, the current hours,
minutes and seconds will be displayed. The “ * ” button moves the cursor to the left and the “ # '”button
moves the cursor to the right. When all digits have been entered, press the TRANSMIT button to then enter
the month, day and year. Again, when all digits have been entered, press the TRANSMIT button. Upon
doing so, the unit will exit diagnostics.
