A system in which all or some of the circuits are actuated by automatic devices, such as fire detectors, is called what?

• A. Automatic fire alarm system
• B. Manual fire alarm system
• C. Central monitoring system
• D. Standby system

Answer: (A)

Automatic activation of alarms by detectors is the defining idea. When detectors such as smoke or heat sensors trigger the system, the control panel starts the alarm automatically, without requiring a person to intervene. This makes it an automatic fire alarm system. Manual fire alarm systems, by contrast, rely on someone pulling a manual call point to raise the alarm. A central monitoring system describes how signals are supervised or transmitted to a remote center, not how the alarm is triggered, and a standby system refers to backup power or standby components, not automatic activation.
