can be attached to the system to provide greater functionality.
Backup Battery
5.02. The system power supply (PSU) supports a backup battery package rated at 24 (12

applies system cut over to battery when main power is removed, and provides
system shutdown when battery power falls below a specified level.
5.03. The battery leads connect at terminals located on the power supply unit card inside
the cabinet. Length of time system operation is maintained under battery power
depends on battery capacity. Normal life expectancy for a 24 volt battery is 1 hour.
