DK424i Configuration
Reserve Power
Two or four customer-supplied 12VDC reserve batteries can be connected to the system to
maintain normal operation during a power failure (see
). The batteries are
kept in a highly-charged state by the standard power supply and must be connected when the
system is operating normally. Fully charged batteries must be connected when normal AC power is
available, batteries cannot be connected after/during an actual power failure.
