Question 3

Which component of a fire suppression system activates the alarm when water begins to flow through the sprinkler piping?

Accepted Answer

Flow switch (water flow detector)

Answer

A flow switch detects water movement through the pipes and sends a signal to the fire alarm system to indicate sprinkler activation.

Question 4

Carbon dioxide (CO2) fire suppression systems pose what primary life safety hazard to occupants?

Accepted Answer

Oxygen displacement causing suffocation in enclosed spaces

Answer

CO2 extinguishes fires by displacing oxygen, which means it can create life-threatening oxygen-deficient atmospheres in enclosed occupied spaces.

Question 5

What is the purpose of an inspector's test valve on a wet pipe sprinkler system?
