FACU is a ___.

• A. fire alarm circuit ungrounded
• B. fire alarm connection underground
• C. fire alarm city utility
• D. fire alarm control unit

Answer: (D)

FACU stands for Fire Alarm Control Unit, which is the central brain of a fire alarm system. It processes signals from initiating devices like detectors and manual pull stations, and it controls the outputs such as horns, strobes, and other system actions. It also monitors circuit integrity and manages power and supervision for the entire system. This is why the option describing the central control unit is the correct one—the other choices refer to wiring conditions or external power sources, not the device that coordinates and controls the fire alarm system.
