Which statement describes the role of a fire alarm control panel?

• A. Controls external lighting only.
• B. Provides power and monitor circuit integrity.
• C. Stores user credentials.
• D. Functions as a siren control only.

Answer: (B)

Fire alarm control panels act as the central hub and power source for the system. They house the main power supply and a backup battery to feed all initiating devices and notification appliances, and they continuously supervise each signaling circuit for faults such as open or shorted wires. When a device is triggered, the panel processes that input and activates the audible/visual alarms and other system actions. This combination—providing power and monitoring circuit integrity—captures the essential role of the panel. The other statements miss key aspects: the panel’s job isn’t limited to external lighting, it doesn’t store user credentials, and it isn’t only a siren controller.
