Final answer:
The fire protection system is divided into two separate subsystems: active and passive.
Step-by-step explanation:
The fire protection system is divided into two separate subsystems: active and passive.
The active subsystem includes components that are activated when a fire occurs, such as fire alarms, fire sprinkler systems, and fire suppression systems. These systems detect the presence of fire and initiate a response to extinguish or control it.
The passive subsystem, on the other hand, consists of measures that are in place to prevent the spread of fire and protect occupants, such as fire-resistant building materials, fire doors, and smoke barriers.
