Sentence 6.5.1.1.(2)

Intent 1:

To limit the probability that deficiencies in emergency electrical power supply systems will go unnoticed, which could lead to corrective action on such deficiencies not being taken, which could lead to emergency electrical power supply systems not operating as originally intended when there is a loss of normal power in a fire situation, which could lead to the inability of the emergency electrical power supply systems to supply fire protection systems, which could lead to:

• sprinkler, standpipe and hose systems, and other fire suppression systems [that rely on booster or fire pumps, or electrical power] not being able to control or suppress a fire, which could lead to the spread of fire, and
• smoke management systems not being able 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.
