What is the role of the load side in a fire alarm circuit?

The load side of a fire alarm circuit plays a crucial role in connecting sensors and alarms within the system. 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.

This choice highlights the practical application of the load side in a fire alarm system, focusing on its function in transmitting the necessary signals that relay information about potential hazards.
