In a fire alarm system, what is the alarm's primary function?

• A. Detects
• B. Notifies
• C. Responds
• D. Records

Answer: (B)

The alarm’s primary function is to notify occupants. When detectors sense smoke or heat, the fire alarm control panel triggers audible and visual notification devices—horns, bells, and strobes—to warn people and prompt evacuation. This distinguishes the alarm from sensors, which perform detection, and from logging or recording functions, which track events for records. The alarm may also trigger other actions or alert monitoring services, but its essential role is fast, clear warning to occupants so they can get to safety.
