PE-11(2) Alternate Power Supply — Self-contained
Control enhancement of PE-11 Emergency Power
Control
Provide an alternate power supply for the system that is activated [Assignment: Selection: manually | automatically] and that is:
Self-contained;
Not reliant on external power generation; and
Capable of maintaining [Assignment: Selection: minimally required operational capability | full operational capability] in the event of an extended loss of the primary power source.
Discussion
The provision of a long-term, self-contained power supply can be satisfied by using one or more generators with sufficient capacity to meet the needs of the organization.
