The critical component for alerting occupants during a fire event is alarm devices. These devices are designed specifically to detect fire or smoke and emit warnings, often through loud sounds or visual signals, to ensure that all building occupants become aware of the situation and can react accordingly to evacuate or follow safety protocols.

In a fire emergency, timely notification is essential for minimizing harm, which alarm devices accomplish through automatic detection and alert systems. These can include smoke detectors, fire alarms, and notification systems, all of which play a crucial role in fire safety management.

While sprinklers, valves, and pipes are essential components of a fire protection system, their primary functions relate to controlling or suppressing fires rather than directly alerting occupants. Sprinklers act to extinguish or control fire spread, valves regulate water flow within the system, and pipes are the conduits that move water to where it is needed to fight a fire. In contrast, alarm devices are explicitly designed to notify people, making them a vital part of any fire safety system.
