Sentence 3.2.7.5.(1)

Intent 1:

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

• 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, and
• smoke management systems to control smoke conditions as originally intended, which could lead to the migration of smoke from one floor area or fire compartment to other parts of the building.

This is to limit the probability of damage to the building.
