• A. Fire Alarm Control Unit - FACU
• B. Fire Alarm Control Panel - FACP
• C. Fire Alarm Relay Node
• D. Alarm Initiation Module

Answer: (A)

The central brain of the fire alarm system is the component that continuously monitors circuits and equipment, collects input from initiating devices (like smoke detectors and pull stations), controls the notification appliances (horns, strobes), and transmits alarm signals off site. This role is fulfilled by the Fire Alarm Control Unit, which is the modern term for what used to be called the fire alarm control panel (FACP). The other options refer to smaller pieces or interfacing devices: a relay node handles signaling interfaces rather than overall control, and an initiation module processes initiating signals without managing the entire system or off-site transmission.
