General Information
The Model 10962-001 and 10962-002 AMI Redundant Controllers (ARC) are designed for GAI-Tronics

or public address systems requiring redundant alarm tone/speech generators. They work in
conjunction with the GAI-Tronics Model 10959-105, -106, -207, and -208 Audio Messenger Interface
(AMI) units. The AMI acts as the alarm tone/speech generator to produce emergency tones and/or pre-
recorded speech messages. Refer to Pub. 42004-399 for more information on the Model 10959-105 and -
106 AMIs and Pub. 42004-404 for Models 10959-207 and -208 AMIs.
The ARC and AMI devices can be connected in two different configurations depending on the system
requirements. If both AMIs are to be installed at the same location, one Model 10962-002 ARC Module
can be used to control both AMIs. Refer to Figure 3. If the AMIs are to be installed at separate locations,
one Model 10960-001 ARC Module is required at each location. Each ARC will control its respective
AMI. Refer to Figure 4.
In either configuration, one AMI acts as the “active” alarm generator and the other AMI acts as the “back-
up.” The ARC module(s) control which AMI is active and which is back-up.
During normal alarm operation, input contacts are applied simultaneously to both the active and back-up
AMIs. The ARC module(s) allow only the active generator to play the tone/speech message over the
system speakers. The back-up AMI is held in standby mode to prevent audio mixing of the two AMI
tone/speech messages.
In the event of a failure of the active AMI, the back-up AMI becomes active and plays its tone/speech
message over the system speakers.
