Which circuit is dedicated to powering and signaling notification devices in a fire alarm system?

• A. NAC
• B. FACU
• C. EOL
• D. Zone

Answer: (A)

The main idea here is identifying which circuit specifically feeds and controls the devices that warn people: the Notification Appliance Circuit. This circuit is the path that both powers and sends the signaling to audible and visual notification devices like horns, bells, and strobes when the fire alarm system is activated. The other terms refer to different parts of the system: the Fire Alarm Control Unit is the panel itself, End-of-Line is used to supervise a circuit for faults, and Zone is a grouping of devices for area-based monitoring. So the circuit dedicated to powering and signaling notification devices is the Notification Appliance Circuit.
