What is one of the functions of a sprinkler head?

One of the primary functions of a sprinkler head is to automatically activate and deliver water to suppress or control a fire when it reaches a certain temperature, providing immediate assistance in fire control. While sprinkler heads can work in conjunction with fire alarm systems, it is important to note that sprinkler heads themselves do not report troubles or detect smoke. Their main role is to disperse water directly onto the fire, helping to cool it and reduce its spread.

In the context of the choices provided, the ability to activate the fire alarm system aligns with the integration of safety systems found in modern fire safety designs, where the activation of sprinklers may trigger alarms, alerting occupants and emergency services to the presence of a fire. Thus, in this context, activating the fire alarm system is crucial as it ensures a timely response from firefighting teams and encourages evacuation measures.
