Which component of the fire alarm system serves as the "brain"?

The fire alarm control panel functions as the "brain" of the fire alarm system because it is the central hub that processes information from all connected devices, such as smoke detectors, heat detectors, and manual pull stations. When these devices detect smoke, heat, or manual activation, they send signals to the control panel. The panel interprets these signals and initiates the appropriate response, which may include sounding alarms, notifying the fire department, or triggering other safety protocols.

Moreover, the fire alarm control panel is responsible for monitoring the system's integrity, ensuring that all components are functioning correctly, and providing diagnostic information in the event of a fault. This central role is critical for the system's overall effectiveness in alerting occupants and enabling a timely response to fire incidents.
