3.2.7.6.(1)

Intent 1:

To limit the probability that emergency power supply systems will not operate as originally intended when there is a loss of normal power, which could lead to the inability of the emergency power supply systems to supply emergency lighting systems to illuminate floor areas and egress routes, which could lead to safety hazards [bumping, tripping, falling, etc.], which could lead to harm to persons.

Intent 2:

To limit the probability that emergency electrical power supply systems will not meet proper standards, which could lead to emergency electrical power supply systems not performing in the way intended when there is a loss of normal power in an emergency situation, which could lead to the inability of the emergency electrical power supply systems to supply emergency systems, which could lead to the inability of:

• fire alarm or voice communication systems to promptly notify persons in the building,
• emergency lighting systems to illuminate egress routes, and
• elevator systems to be used in emergency response operations, which could lead to delays in emergency response operations.

This is to limit the probability of delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
