Which of the following is NOT typically considered a main component of a fire alarm system design for a small to mid-size building?

• A. Decorative lighting
• B. Initiating devices
• C. Notification devices
• D. Power supply and battery

Answer: (A)

The main idea is understanding what makes up a fire alarm system: detection, signaling, control, and reliable power. Initiating devices are the ways the system detects or is triggered (smoke/heat detectors, manual pull stations). Notification devices are what occupants hear and see during an alarm (horns, bells, strobes). The power supply and battery ensure the system keeps functioning during power outages and maintains backup operation. Decorative lighting doesn’t contribute to detecting a fire or delivering an alarm, and it isn’t integrated into the fire alarm’s control, signaling, or power framework. It’s part of the building’s general electrical/lighting design, not a core component of the fire alarm system.
