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 in a
fire situation, which could lead to the inability of the emergency
power systems to supply fire protection 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,
- sprinkler, standpipe and hose systems, and other fire
suppression systems [that rely on booster or fire pumps, or electrical
power] to control or suppress a fire, which could lead to the spread
of fire,
- 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 2:
To supersede the requirements of Sentence 6.5.1.1.(1).
