What is fire panel?

A fire panel, also known as a fire alarm control panel (FACP), is the central control unit of a fire alarm system. It receives signals from fire detection devices (like smoke detectors, heat detectors, and manual pull stations), processes these signals to determine if a fire exists, and then initiates appropriate actions such as activating alarms (horns, strobes), notifying the fire department, and controlling building systems (e.g., shutting down HVAC, releasing fire suppression systems). Fire panels are crucial for early fire detection and response in buildings.
