Which item is NOT part of the fire protection triangle?

• A. Alarm system
• B. Fire detection system
• C. Fire suppression system
• D. Firestop system

Answer: (A)

The fire protection triangle focuses on the active steps taken once a fire occurs: detect, alert, and suppress. A fire detection system is used to spot a fire early, triggering an alarm system to warn occupants and often spawning suppression actions. A fire suppression system is what actually controls or extinguishes the fire. Firestop systems, however, are passive protections that maintain compartment integrity by sealing openings to slow fire spread; they don’t participate in the active sequence of detecting, alarming, and suppressing. So the item that does not belong in the triangle is the firestop system.
