• Requirement

    Provide an alternate power supply for the system that is activated [Selection: manually; automatically] and that is:

    1. Self-contained;
    2. Not reliant on external power generation; and
    3. Capable of maintaining [Selection: minimally required operational capability; full operational capability] in the event of an extended loss of the primary power source.

    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.
