AA-100/AA-120 Audio Amplifier
Audio amplifiers provide the following features:
 Built-in Supervision  Each audio amplifier contains a set of normally-
open trouble contacts that close to light an LED showing the type of
trouble. Types of trouble include: brownout, battery failure, audio
output wiring failure (if set for four-wire output), and amplifier failure.
During total loss of primary AC power, all LEDs extinguish to conserve
battery power.
 Backup  You can set up an audio amplifier as a backup amplifier for
multiple amplifiers. If an amplifier fails, the control panel automatically
switches to the backup amplifier.
 Speaker zone selection  Set by control-by-event or set manually using
control switches on the VCM-4, DCM-4, or ACM-16AT modules.
