Battery Standby
Sleep Mode
When Audio Booster is in the standby mode and is on battery backup, the
amplifier section shuts down to conserve battery power.
The Two Wire Mode also shuts off non-alarm functions on the SP40/2. When a
n
alarm signal
sends a message to the Audio Booster the amplifier section is reenergized and
broadcasts the message.
The Four Wire Mode allows non-alarm functions on the SP40/2. An Auxiliary
NAC/CC input wakes the Audio Booster for broadcast.
