AMG-1/AMG-EAudio Message Generator
AMG-1/AMG-E
Overview An AMG-1/AMG-E produces tones and messages. You can set up an AMG to
automatically activate programmed tones or messages through an EIA-485
communications circuit loop or manually select tones and messages. Operating the
AMG involves viewing the LEDs for status information and operating the microphone
and switches.
Each AMG-1 contains one output channel. To set up a secondary channel for dual
channel operation, install an additional AMG-1 or AMG-E. Each AMG can directly
drive up to fifty audio amplifiers.
An AMG can store and use up to four digitally-recorded voice messages. Each voice
message can be up to 24 seconds long. Table 19 contains details of the two types of
digital messages available:
