UPS
Configuration
Note: ON = 0; OFF = 1.
DIP Switch SW1. Controls various UPS functions.
SW1-1. Set to 0. Used when the UPS must be retrofitted to for Intelligent Power Supply
capabilities.
• Position 0: UPS acts like an Intelligent Power Supply in terms of messages sent to and
received from the master controller.
• Position 1: UPS does not use Intelligent Power Supply functionality at all.
SW1-2. Set to 1 unless UPS B-tap is providing power to a 25-Watt Amplifier. Controls
how the amplifier uses the backup battery.
• Position 0: Amplifier switches to battery backup when told to do so by the master
controller.
• Position 1: Amplifier switches to battery backup upon loss of AC power.
SW1-3 through SW1-6. These switches work together to configure the UPS for different
types of batteries (or no batteries at all). Refer to Table B-4 to determine what settings
should be used.
