It is responsible for receiving signals from fire detection devices like smoke detectors or heat detectors, as well as supplying power to notification devices such as horns, strobes, or bells. Essentially, this side of the circuit is where the actual fire detection and alarm components interact, ensuring that when a sensor detects a fire or emergency condition, the associated alarms are activated to alert occupants of the building.
