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: input power brownout, loss of low-level supervision tone at the input,
battery failure, audio output wiring failure (if set for four-wire looped 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.
