Sentence 6.5.1.3.(1)

Intent 1:

To limit the probability that emergency responders will not be able to [manually] start, or will be delayed in [manually] starting, an emergency power system and to switch on essential loads when there is a failure of the system to start automatically, which could lead to the inability of the emergency power systems to supply emergency lighting systems to illuminate floor areas and egress routes, which could lead to safety hazards [such as bumping, tripping, falling, etc.], which could lead to harm to persons.

Intent 2:

To limit the probability that emergency responders will not be able to [manually] start, or will be delayed in [manually] starting, an emergency power system and to switch on essential loads when there is a failure of the system to start automatically, which could lead to the inability of the emergency power 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, which could lead to delays in the evacuation or movement of persons to a safe place,
• emergency lighting systems to illuminate egress routes, which could lead to delays in the evacuation or movement of persons to a safe place,
• smoke management systems to control smoke conditions as originally intended, which could lead to delays in emergency response operations, which could lead to delays in the evacuation or movement of persons to a safe place, and
• elevator systems to be used in emergency response operations, which could lead to delays in emergency response operations, which could lead to delays in the evacuation or movement of persons to a safe place.

This is to limit the probability of harm to persons.

Intent 3:

To supersede the requirements of Sentence 6.5.1.1.(1).
