The central unit that controls the sensors and detectors it is connected to. In essence, it is the brain of the entire security system. Each sensor reports to the control panel so it can translate them and determine if they need to be forwarded to the central monitoring station.
The fire alarm control panel is the central computer or “brains” of a fire alarm system. Every device on the security system reports back to the control panel with supervisory signals and alarm signals. An FACP can be connected with a central monitoring station through several unique signal communication paths, reducing the chances of the signal being lost on the way to the central monitoring station.
